Become the Process Miner of the Year 2017!

Process Miner Of The Year 2017

Last year, we introduced the Process Miner of the Year awards to help you showcase your best work and share it with the process mining community.

This year, we will continue the tradition and the best submission will receive the Process Miner of the Year award at this year’s Process Mining Camp, on 29 June in Eindhoven.

Have you completed a successful process mining project in the past months that you are really proud of? A project that went so well, or produced such amazing results, that you cannot stop telling anyone around you about it? You know, the one that propelled process mining to a whole new level in your organization? We are pretty sure that a lot of you are thinking of your favorite project right now, and that you can’t wait to share it.

What we are looking for

We want to highlight process mining initiatives that are inspiring, captivating, and interesting. Projects that demonstrate the power of process mining, and the transformative impact it can have on the way organizations go about their work and get things done.

There are a lot of ways in which a process mining project can tell an inspiring story. To name just a few:

Of course, maybe your favorite project is inspiring and amazing in ways that can’t be captured by the above examples. That’s perfectly fine!

How to Identify Rework in Your Process

[This article previously appeared in the Process Mining News — Sign up now to receive regular articles about the practical application of process mining.]

If you are involved with process improvement, then reducing rework is most likely one of your concerns.

Two common causes for rework are:

  1. The task was not done right the first time, so someone has to go and do it again.
  2. Information that would have been necessary to work on a case was missing, so it had to be sent back.

Rework is bad because it adds to the workload (and costs) of the company, because it delays the process completion time for the customer, and because — due to the extra effort — it often impacts the completion times for the following cases as well.

Process mining can help you to identify and pinpoint rework patterns in your process. By letting the process mining tool map out your actual process based on the IT data, you will be able to see where rework occurs, how often, and which process categories are affected by it.

Of course, once you have found where and how often rework occurs, you will still have to go and talk to the people in your process to find out why this is happening. But you will be armed with objective information and visual evidence that will be enormously useful to engage the people who are responsible for the process, and to focus the discussion on facts rather than keep arguing about opinions and gut feeling.

How come that people don’t know about the rework already? It is normal that not everything goes according to plan all the time. But because each of the employees handles just a few “exceptional” cases, what seems to be a small extra step here and there amounts to a lot of waste if you look at the complete picture. Sometimes, this effect is called “hidden factory”. With process mining, you will be able to provide an objective overview about the complete process and make the hidden process patterns visible.

For example, the improvement of a form at the website of a consumer electronics manufacturer reduced the amount of missing information in a refund service process, both reducing the amount of work on the side of the service provider (who had to retrieve the missing information) and reducing the process completion times for this critical consumer-facing process.

The solution does not always need to be technical either. For example, in a call center the increase of repeat calls typically indicates a quality problem: The people who had called earlier needed to call again because their problem was not solved in the first call. If the agents had been instructed to keep the call times as short as possible, this might seem to save money at first. However, in the long run it does more harm than good, because the customers are less happy and keep calling back. Shifting the measurement focus to ‘first time right’ can greatly enhance both the customer experience and the efficiency at the call center.

With process mining, you will have the process with all its problems right there, magically and objectively, at your fingertips. This is exactly what makes it possible for your team to focus on the why (and not the what) in the process analysis, which is one of the big benefits of process mining.

In this article, you will learn six tips for how to analyze rework with process mining (download the free demo version of the process mining software Disco here to follow along with the instructions).

Let’s get started!

1) Filter direct loops with the ‘Filter this path…’ shortcut

Rework manifests itself in different kinds of loop patterns in your process. Often, you will directly see the loop in your process map.

For example, take a look at this call center example below (one of the demo data sets you can download from the Disco website). The process map shows cases that are started by inbound calls, and you can see from the self-loop at the ‘Inbound Call’ activity that there are repeat calls for some cases. You can click on the images to see a larger version.

To focus on these repeat calls, you can click on the loop arrow and press the ‘Filter this path…’ button in the overview badge (see picture below).

You will be taken to a pre-configured Follower filter for this path and can simply press the ‘Apply filter’ button in the lower right corner. (Press the ‘Copy and filter’ button instead if you want to save your repeat call analysis for later.)

As a result, you can see the new process map for the repeat calls and you can see that 16% of all cases show this repeat call pattern.

2) Catch global repetitions with the ‘Eventually follows’ option

Now, this gives us the direct repetitions for the ‘Inbound Call’ activity. But wat about repeat calls that come in after some other activity happened in the process?

For example, there may have been an initial call from the customer. Then the agent called back (‘Outbound call’ activity) and then, some time later, the customer calls again (another ‘Inbound Call’). In this scenario, there has been a repeat call, but the two calls did not happen directly after each other. So, they are not reflected by that self-loop in the process map that we focused on in scenario 1) above.

What can you do if you still want to count this case that includes the pattern ‘Inbound Call’ -> ‘Outbound Call’ -> ‘Inbound Call’ in your repeat call analysis result?

That’s easy: You can simply go back to your Follower filter (click on the filter symbol in the lower left corner) and change the mode from ‘directly followed’ to ‘eventually followed’ (see below).

Your filter result now includes all cases that at any point in the process had a repetition (or more) of the activity ‘Inbound Call’.

3) Filter loops of the same type

So far, we have seen how you can filter cases where the same activity occurs multiple times. However, sometimes the rework patterns you want to analyze are more general.

For example, you may have combined multiple fields to unfold your activity name in additional dimensions (see the article Change in Perspective with Process Mining for three alternative view points that you can try for your own process).

The screenshot below shows how the ‘Operation’ and the ‘Agent Position’ columns were both configured as part of the activity name during the import step.

As a result, you can see a more fine-grained view of the call center process: The hand-over points between the first-level support staff (FL) and the backoffice employees (BL) are now explicitly represented in the process map (see below).

This is great, but if you want to filter for repeat calls as before, you now have multiple instances of the type ‘Inbound Call’ in your activity list (‘Inbound Call – FL’ and ‘Inbound Call – BL’). You could select multiple activities in the list, but you can also simply use the more general type attribute that you care about for filtering (see below).

Now, you can define your rework pattern directly on the ‘Operation’ field type ‘Inbound Call’ (see below).

The possibility to choose another attribute for your rework pattern in the Follower filter is also handy if you don’t want to focus on activity repetitions in the first place. Instead, you might be interested in, for example, cases that are reworked by the same person, the same department, or any other attribute dimension that you have included in your data set.

4) Filter for repetitions without knowing where they are

But what do you do if you don’t really know which loops you should be focusing on? Say, you want to filter all cases that have some rework in it, regardless of which activity was involved in the rework.

You can use the Follower filter to do that, too. Take a look at the Sandbox example that comes with Disco to see how:

First, click on the filter symbol in the lower left corner to add a filter.

Then, directly add a Follower filter from the list of filters (see below).

In the Follower filter settings, first select all activities as reference and follower values. This by itself will not yet have any effect, because if you match every activity pattern in the data set then all cases will be retained.

But now comes the trick: Below the reference and follower event list you can also add an additional constraint based on another attribute, which can be asked to have the same or a different value. Often, this is used to find violations of segregation of duties or analyze other compliance rules, but here we are using the ‘the same value’ option to filter repetitions of any kind.

Enable the checkbox Require and configure the settings so that it says the same value of Activity as shown below. Then click ‘Apply filter’.

The result of this filter are all cases that have some repetition somewhere in the process, no matter which activity has been repeated. We can see that in total 41% of the cases have some form of rework in this process.

5) Visualize repetition hotspots with the ‘Max repetitions’ option

To see where the biggest rework occurs, you can switch the process map view to ‘Max repetitions’ as shown below. The numbers in your process map will change to show the maximum number of times an activity was performed for a single case.

In the purchasing example, the activity ‘Amend Request for Quotation Requester’ really stands out as it has been repeated up to 12 times in the same case.

6) View detailed repetition statistics by focusing on a single activity

We now know that activity ‘Amend Request for Quotation Requester’ has been performed up to 12 times for the same case, but how many cases exactly repeated this activity so often? Just one? How many repetitions are most typical?

If you want to focus in on one specific repeating activity in more detail, you can do the following:

First, click on the activity you want to focus on and press the ‘Filter this activity…’ button in the overview badge (see below).

Then, in the Attribute filter change the mode from ‘Mandatory’ to ‘Keep selected’ as shown below (we only want to keep this one activity right now). Use the ‘Copy and filter’ button to save this rework analysis in your project.

After applying the filter, change from the Map view to the Statistics view and …

… change to the ‘Events per case’ statistics to see how many times this particular activity was performed for how many cases.

For example, now we can see that there was indeed just one case that performed activity Amend Request for Quotation Requester 12 times, and that there were three cases, where this activity was performed 6 times (see screenshot below).

For each of the scenarios above, you can then further analyze the context of your rework pattern by looking at further statistics. For example, you might want to see which process categories (regions, product types, etc.) are most affected. And you can inspect individual cases in the Cases View to get more context information and talk to the people who were involved in these cases to learn what the reason was and how they would improve it.

Which rework patterns can you find in your own process? If you need help, just get in touch and we will help you to get started!

Skills and Roles Needed For Your Process Mining Project

Skills and Roles needed for Process Mining

One of the challenges of applying process mining is that different skills need to come together to make it a success. Sometimes, you will find multiple skills in one person, but often you need to put together a multi-disciplinary team of people complementing each other.

Here is an overview of the most important roles that your team should cover.

IT Administrator

While you will define what kind of data you need for your process mining project, you will typically not extract the data from the IT system yourself. Instead, you will work together with the IT department who will extract the data for you.

The IT administrator will also be able to help you clarify questions about the data itself and provide you with a data dictionary about the meaning of the different data fields.

It is a good idea to involve the IT team early in your project, so that they understand what you want to do and what kind of data you need.

Data Specialist

Some systems can provide a data extract that can immediately be used for your process mining analysis. However, more often than not you will need to combine different data sources or re-format your data in some way.

While most process analysts will be able to re-work their source data in Excel, for larger data sets you need skills to merge and process your data via SQL, ETL tools, or via scripting languages like Python or R. For such projects, you need to have someone on board who can do these data transformations for you.

Data / Process Analyst

The actual analysis of the data is the home turf of the process mining analyst. Keep in mind that the data analysis does not only cover the answering of your process questions but also includes tests for data quality and the fixing of data quality problems.

If you want to become a process mining expert, consider attending a process mining training to learn all the building blocks and the methodology that is involved.

Business Analyst

If your project is a process improvement project, it is a very good idea to make sure that you have a Lean Six Sigma practitioner or some other kind of process improvement expert on board. They are trained to suggest and evaluate process improvement alternatives from a business perspective.

If your analysis falls into another process mining use case — for example, you may be using process mining to support your internal audits — then you need someone in your team who is an expert in this profession.

Project and Change Management

Just like with any other project, you need project management skills to scope your project, define realistic milestones, and manage the progress of the project.

Furthermore, actually implementing the process changes is necessary to realize the benefits from your process mining analysis. You need a change manager to help the business unit through the process changes that come out of your process mining project.

Process Owner

In many situations, the process mining team will perform projects for different business units in the company. To ensure that your process mining analysis will have an impact, you need a strong sponsor who is actually interested in the results.

A sponsor who crosses their arms and says “Surprise me” is a read flag. Instead, look out for someone who is also enthusiastic about the possibilities of process mining and who is willing to provide you with the support and the resources that you need.

Domain Expert

One of the resources that you need for a successful process mining project is access to a domain expert. Typically, this is not the process manager themselves but another process expert in their team.

This subject matter expert will help you define the analysis questions for the project, perform the data validation session with you, and review intermediary findings in a series of workshop sessions throughout the project.

Privacy Officer

A last stakeholder who is not in the picture above but nevertheless very important is the privacy and ethics expert in your company. Read our guidelines on Privacy, Security, and Ethics in Process Mining here and take those lessons aboard in your process mining project.

How to Perform a Bottleneck Analysis With Process Mining 3

When you perform a process mining analysis, then the discovered process map and the variants are only the starting point. You then want to dive deeper into the process based on the questions that you have about it.

One of the typical questions is about the performance of the process. For example, you may have a service level agreement (SLA) with respect to the overall throughput time of the process. Within Disco, you can analyze the case duration distribution and you can filter your data to focus on the slow cases to find out where in the process they lose so much time (see also the video at the top for a demonstration of how to do this).

Once you discover a bottleneck in your process, the animation is a very powerful tool to visualize the bottleneck to your co-workers. Rather than just giving them abstract statistics and charts, they can literally see where a lot of the cases are piling up and where the queuing occurs (see below). This will help you to explain your findings and engage them in discussions about how the process can be improved. As soon as a bottleneck has been resolved, you can focus on the next one to support a continuous improvement of your process.

Process Mining Animation in Disco

Once you dig into the performance analysis for your process, there are two things to know that can be helpful. So, in this article, we want to give you these two tips that will help you perform better bottleneck analyses on your own data.

Tip No. 1: Consider the median instead of the mean

All the performance metrics in Disco, for example, the case durations, the activity durations, but also the performance metrics in the process map, give you both the mean and the median duration.

Often, there is quite a difference between the two. For example, if you look at the case duration below (click on the image to see a larger picture) then you will notice that the mean case duration is 21.5 days while the median case duration is just 12 days — That means the median case duration is almost half of the mean case duration for this process!

The reason that this can happen is that the mean is much more susceptible to outliers. To understand why, let’s take a look at how both the mean and the median are calculated. In the figure below, you can see seven measurements lined up according to their size. For example, these could be seven cases of which we have measured the throughput time: Two cases were measured with 1 day throughput time, one case was measured with 2 days throughput time, three cases were measured with 3 days throughput time, and one case — our outlier — had a throughput time of 30 days.

Now, the median is defined as the value in the middle of the lower 50% and the higher 50% of measurements. So, 3 would be the median value in this example, because half of the cases took longer (or equally long) and half of the cases were faster. In contrast, the mean or average value is calculated as the sum of all values divided by the number of values. So, the mean yields 6.14 in this example. The mean is more than twice as high compared to the median, because the mean is much more influenced by the one extreme case with the 30 days throughput time.

Illustration of the median compared to the mean

In practice, many processes have a distribution similar to the picture above. For example, your customer service process may typically take up to two weeks, but you have these few, very complicated cases that took one or two years to resolve. Or when a typical incident can be closed with 8-10 steps, there is this one extreme case that was ping-ponged between different groups more than 200 times.

In such processes, the median (also known as the 50th percentile) gives you a much better idea of the typical performance characteristics of a process than the arithmetic mean. Therefore, the median can often better point you to the places in the process that typically are quite slow. For example, from the mean durations visualized in the illustration below on the left, you can get the impression that basically the whole area on the left of the process is problematic in terms of performance. The median performance view, shown on the right, makes it clear that the bulk of the problems actually lies with one activity on the lower left.

Mean vs Median Performance Perspective in Process Map

Of course there are still situations, where you might want to use the mean. One reason can be that it is easier understood by people who are not statistically minded. Or your KPIs might be defined based on the mean, so you should use the mean for your analysis, too. But keep in mind that if you have a skewed distribution with heavy outliers, the mean can be misleading and the median will be a better metric to get a sense of what a typical value looks like.

Tip No. 2: Combine total duration with the median

The second tip that we want to give you is to keep in mind that neither the mean nor the median take the frequency into account. This can be a problem, because you want to focus your improvement efforts on those places in the process, where they can have the most impact.

For example, let’s take a look at the process map below. We have used the median for the performance visualization and it looks like that path that typically takes 5.6 days is the biggest problem.

However, once we switch to the frequency view, we can see that the path right next to it is about 10 times as frequent. So, although the median delay on that path was just 3 days (instead of 5.6 days), the impact of improving this particular bottleneck will be greater.

The best way to take the frequency into account in your bottleneck analysis is to use the total duration (see the screenshot below). The total duration gives you the sum of all the delays in the data set and, therefore, naturally takes both the actual delays but also the frequency into account. So, you can clearly see the big, fat, red arrow in the process map point to the biggest bottleneck that you should address first.

The only drawback of the total duration is that the numbers easily add up to months or years. As a result, it is hard to get a sense of what the typical delay of a path or activity is in the process. To address this, you can add the mean or median duration as a secondary metric (see screenshot below). The secondary metric will appear in smaller font below the primary metric in the process map. We can see the 5.6 days median measurement re-appear in the process map, but it is now clear that the path to the left is the bigger problem we should focus on.

Now, you have the best of both worlds: The total duration as the primary metric is driving your attention to the right places in the process map and helps you to focus on the high-impact areas for your improvement project. At the same time, you can easily see what the average or the typical delay is in this place through the secondary metric.

Success Criteria for Process Mining 2

This article has been previously published as a guest article on KDnuggets, on the Data-Science-Blog (German), in the AutomatiseringGids (Dutch), and in the Process Mining News.

By using Process mining, organizations can see how their processes really operate. The results are amazing new insights about these processes that cannot be obtained in any other way. However, there are a few things that can go wrong.

Process mining doesn’t usually begin as a top-down initiative. Typically, there are a few enthusiastic people who want to do something with it. When they start a process mining initiative within their organization, they need to bypass the following classic pitfalls.

First of all: Being too fascinated with the technology itself can lead to an inability to show the added value from a business perspective. Secondly: An unrealistic image of the data availability, coming from the promise of Big Data, can lead to overblown expectations. And the third pitfall: Due to a wrong understanding of what process mining can do, the first project is often too ambitious in scope. Too much is being promised and it takes too long before the first results can be shown. This undermines the belief within the business that process mining produces a good ROI. A failed project then not only leads to a decrease in the entrepreneurial and innovative spirit among the process mining enthusiasts, but there is also the risk that process mining will not be picked up again in a new project for years.

In this article, Frank van Geffen and Anne Rozinat give you tips about the pitfalls and advice that will help you to make your first process mining project as successful as it can be.

Success Factors

So, how can you make sure that your process mining initiative is successful? What makes the difference between success and failure? We provide you with a roadmap (see Figure 1) and discuss four success factors.

Figure 1: Roadmap to making your process mining project successful

Success factor No. 1: Focus on the business value

Success factor No. 2: Start small, think big

Figure 2: To fully communicate what process mining is, you need to understand what Process Mining is not

Success factor No. 3: Work hypothesis-driven and in short cycles

Success factor No. 4: Facts don’t lie

Because of all these challenges you can sometimes lose track of the great possibilities that process mining provides. But don’t despair and look forward to an exciting journey!

With process mining it is possible to look at your processes at a much more detailed level. You connect to the real processes and you analyze them based on facts. And after each process change, the analysis can be repeated quickly and easily.

Take these success factors into account and you will be amazed by what process mining can do! Download the process mining software Disco to get started and consider joining one of our process mining trainings to learn the full methodology for a successful process mining project.

Process Mining Use Cases: Possible Outcomes 2

Previously, we have looked at who uses process mining and why. Another way to understand the different process mining use cases is to look at the possible outcomes of a process mining analysis.

Process mining requires a skilled human analyst

Process mining allows you to analyze very complex processes. Furthermore, you don’t need to know what the process looks like (just identify the three parameters case ID, activity name, and timestamp) and you can even look at the same process from different perspectives. In turn, process mining is not an automated activity but needs a human analyst to understand the data and interpret the results, and some skills and experience to do it well.

But what exactly could be the outcome of such a process mining analysis?

Possible outcomes of a process mining analysis

On a high level, there are four main outcomes of a process mining analysis (see also picture above). For any process mining project, a combination of these outcomes can apply.

1. Answer

Sometimes, the outcome is just an answer. For example, imagine you are the manager of a process and have received complaints that this process is taking too long. There is an internal Service Level Agreement (SLA) and you want to know whether the complaints are justified (and if so, how often it happens that the SLA is not met). Getting an answer to this question is the primary goal of the process mining analysis.

Another example would be a data science team that supports a customer journey project, where the customer experience is completely re-designed. To make sure that the new system supports the customers in the best way, the data scientists have been asked to analyze what the most common interaction scenarios are.

Finally, think of an auditor who assesses the compliance of a process. The audit report with the summary of their findings will be the main outcome of the process mining analysis.

2. Process change

In many situations, the outcome will be a process change. For example, a particular process step may be automated. There might be organizational changes to address the high workload and shortage of resources in a certain group. An update to the FAQ or website of the company could be made to prevent unnecessary customer calls. Based on the assessment of the audit team, a new control could be implemented in the IT system to reduce the risk of fraud. Or based on the analysis of an outsourced service process at an electronics manufacturer, the contracts with the outsourcing partners will be renegotiated in the next year.

Typically, the analysis will be repeated after some time to see whether the change was as effective as one had hoped. It is easy to repeat a process mining analysis with fresh data to investigate these effects. The outcome of the follow-up analysis can then again be just an answer or result into more process changes.

3. Monitoring

Sometimes, you can also discover a new KPI that was not known before. For example, imagine you are analyzing a payment process where the company can get 2% discount from their suppliers if they pay within 10 days. You realize that there are two main phases in this process: (1) the posting of the invoice to the system and (2) several approval steps, before the payment can be run on two fixed days in the week. You implement an additional reminder to the approvers in the financial system (a process change), which reminds the managers who need to approve the invoice to do so more quickly. But now the late posting of the invoices is the main problem. You realize that if they are not posted within 3 days, there is almost no chance to get the payment through on time. And you want to monitor this new KPI in an automated way.

Like the process change, this will be outside of the process mining tool. But after understanding the process and the data (to know where the measure points for the KPI need to be placed) it is typically easy to add such a new KPI to your existing dashboard or BI system.

4. Optimization and further analysis

Finally, sometimes further analysis is needed after the process mining analysis has been completed. For example, let’s say you analyze the fall-out from a sales process, which means that you are looking at those customers who were interested in your products but for whichever reason never completed the ordering process (their revenue has been lost). You want to follow up with them and be pro-active offering help before it is too late. However, you only want to follow-up with the customers who are most likely to buy.

This would be a scenario, where a data science team sets up and trains a prediction algorithm in one the available data mining or machine learning frameworks. It will be a custom application that is targeted at one very specific problem (predicting which customers you should call). The prediction algorithm gets better over time, learning from the historical data, but to set it up in the first place it helps to understand the process and possible process patterns that might have an influence and, therefore, could be a good parameter in the model.

In addition, there are many scenarios where process miners will perform further analyses in other, complementary tools. For example, a Lean Six Sigma practitioner will want to perform additional statistical analyses in Minitab, data scientists might use data mining tools to discover correlations between the process variants and other attributes in the data, process improvement experts might want to run alternative what-if scenarios in a simulation software, and auditors might take some of the findings from their explorative analysis in Disco to their regular audit tools to include them in the standard check procedures.

All of these tools are specializing in different areas and can be used together. Process mining provides important input for these follow-up analyses by providing a process perspective on the data.


So, what outcomes can you expect from process mining for your own work?

To find out, first start learning more about process mining to fully understand how it works and what it can do. Download the process mining software Disco and contact us for an extended evaluation license to explore some of your own data sets.

Consider joining one of our process mining trainings. Perform a small pilot project and learn about the success criteria for process mining. To create your business case, keep thinking about how process mining fits into your daily work and how exactly it will help your organization.

Process Mining Use Cases: Who Uses Process Mining? 7

Process Mining Use Cases

One of the questions when starting out with process mining is “What is the added value for me and my organization?”. To answer this question, you first have to understand your use case. One ingredient of understanding your use case is to understand who will be using process mining and why.

In the above picture you see some of the most typical places in an organization, where process mining is used. Depending on the role the concrete value will be different. Given your role, you have to think about “How is my job getting easier or better with process mining — compared to not using process mining?”.

Let’s take a quick look at the six use cases above1.

1. Process Improvement Teams

There are many different terms used for process improvement teams in organizations: Process Excellence, Operational Excellence, Process Performance Management, etc. These teams often use Lean Six Sigma methods in their improvement initiatives and, as a central team, help different business units in the organization. Process mining fits very well into their toolbox and allows them to analyze the true processes based on data, rather than through manual inspections and interviews.

Process mining itself is agnostic to the improvement method that you use. This means that it does not matter whether your organization uses BPM, Theory of Constraints, Lean, Six Sigma, or Lean Six Sigma. Process mining does not replace these methods. Instead, the business analysts will use their improvement framework to interpret the process mining results, drive the change, and verify whether the outcome was effective.

The benefit of using process mining in process improvement projects is that the actual processes can be analyzed much faster, and much deeper, than they could be in any manual way. This does not mean that the workshops with process managers and other stakeholders in the business unit go away: Instead, you will start the conversation with them on another level. You can show them the process and say “This is what we are seeing. Do you know why this is happening?” (instead of wasting hours of their time by letting them explain to you how the process works).

2. Data Science Teams

Many organizations have started to build data science teams, because they have recognized the value of increasing amounts of data and they want to be able to make use of it. Data scientists are typically well-versed in all kinds of technologies. They know how to work with SQL, NoSQL, ETL tools, statistics, scripting languages such as Python, data mining tools, and R. And they know that 80% of the work consists of the processing and cleaning of data.

Data scientists are starting to adopt process mining, because it fills a gap that is not covered by existing data-mining, statistics and visualization tools: It can discover the actual end-to-end processes. Process mining also allows data scientists to work much faster. Even if you could write an SQL query that answers your particular process question, the process mining tool shows you the full process right after importing and allows you to directly filter the data without any programming.

Furthermore, data science teams do not analyze data for themselves, but to solve problems and issues for the business. Process mining helps them to communicate their analysis results back to the business in a meaningful way. Charts and statistics are often too abstract when summarizing a process. So, being able to provide a visual representation of the process to the process manager makes your explanation much more accessible to them.

3. Process Managers

Process managers are responsible for one particular process in the organization. The methods they use are often similar to the central process improvement teams (see above), but instead of working with different departments at different times they focus on their own processes and repeatedly analyze them for continuous improvement.

When a process manager adopts process mining, they have the advantage that they have all the domain knowledge available to interpret the data and the process correctly. This is a great advantage, because process mining does not only require expertise in how to do the actual process mining analysis, but the domain knowledge to interpret what you are seeing is absolutely crucial. At the same time, they typically need some training in a process improvement method (like Lean).

Process managers focus on operational questions and process mining brings them an eye-opening transparency about what is actually going on in their process. Once they have completed a process mining analysis, they can easily repeat it to see whether the improvements were as effective as they have hoped.

4. Auditors

The role of internal audit departments is to help organizations ensure effectiveness and efficiency of operations, reliability of financial reporting, and compliance with laws and regulations in an independent and objective manner. External auditors provide assurance from outside the organization.

Both groups can benefit from process mining in many ways. Clearly, processes are not all an auditor looks at. For example, an IT auditor also looks at which system controls are in place to prevent fraud. However, when they do look at processes they typically do it in a very manual way (by looking at the process documentation, interviewing people, and inspecting samples). This is time-consuming and does not guarantee that the actual process problems will be detected.

When auditors use process mining they focus on compliance questions (like segregation of duties and process deviations). The advantage of using process mining is that they can be much faster. Furthermore, they can analyze the full process (not just samples) and, therefore, achieve a higher assurance. They can focus on the deviations (by quickly seeing what goes right) and better identify the true risks for the organization. Finally, the visual representation helps them as well, because in the end they will need to communicate their findings in an audit report.

5. IT Departments

If you look at process mining from the perspective of an IT department, you are mostly concerned about how well the IT systems (or apps, or websites) are working.2 There can be many different reasons to try to understand how IT systems are actually used. For example, you might want to replace a legacy system. Or you might want to scale back unnecessary customizing to make upgrades easier and save maintenance costs.

More recently, organizations have started to analyze the so-called customer journeys by combining click-stream data from their apps and websites with data from other customer interaction channels. The goal to improve the customer experience is typically at the center of these customer journey process mining analyses.

Customer journey processes are often more complex than, for example, administrative processes. Therefore, it is really important to formulate concrete questions and filter down the data to the subset that relates to your question (see this article for 9 simplification strategies). However, if done right, customer journey analyses can contribute greatly to not just improving the usability of websites and apps, but also to shift the perspective from ‘How are we doing things’ to ‘How does the customer experience our service’ in any process improvement project.

6. Consultants

Process mining fits into many types of consultancy projects. Whether you are helping your client to introduce a new IT system (transformation projects), build an operational dashboard, or help them to work more efficiency, in all of these projects you need to understand what the ‘As is’ process looks like.

The most common use case of process mining for consultants is in process improvement projects. As such, the use case is very similar to the one of Process Improvement Teams (see above). But instead of an internal team working with a business unit in the organization, you are coming in as an expert from the outside, bringing with you a fresh perspective and your experience of working with different clients.

Consultants can specialize in many different areas by, for example, focusing on particular industries or IT systems. Furthermore, if you build up your process mining skills, you can help clients to try out or adopt process mining, when they do not have these skills themselves yet.

So, which benefits can process mining bring to you?

To find out, first start learning more about process mining to fully understand how it works and what it can do. Download the process mining software Disco and contact us for an extended evaluation license to explore some of your own data sets.

Consider joining one of our process mining trainings. Perform a small pilot project and learn about the success criteria for process mining. To create your business case, keep thinking about how process mining fits into your daily work and how exactly it will help your organization.

  1. This is not a complete list. There are many more use cases, for example, for Quality Improvement, Software Development, Platform Vendors, Monitoring Outsourcing Providers, Risk Management, etc. We have just listed the areas, where we see process mining being used most frequently right now.  
  2. Note that we are not talking about IT processes like IT Service Management, which in this list would fall under the Process Manager category (see above).

Data Quality Problems in Process Mining and What To Do About Them — Part 11: Data Validation Session with Domain Expert 2

Expert interview

This is the eleventh article in our series on data quality problems for process mining. You can find an overview of all articles in the series here.

A common and unfortunate process mining scenario goes like this: You present a process problem that you have found in your process mining analysis to a group of process managers. They look at your process map and point out that this can’t be true. You dig into the data and find out that, actually, a data quality problem was the cause for the process pattern that you discovered.

The problem with this scenario is that, even if you then go and fix the data quality problem, the trust that you have lost on the business side can often not be won back. They won’t trust your future results either, because “the data is all wrong”. That’s a pity, because there could have been great opportunities in analyzing and improving this process!

To avoid this, we recommend to plan a dedicated data validation session with a process or domain expert before you start the actual analysis phase in your project. To manage expectations, communicate that the purpose of the session is explicitly not yet to analyze the process, but to ensure that the data quality is good before you proceed with the analysis itself.

You can ask both a domain expert and a data expert to participate in the session, but especially the input of the domain expert is needed here, because you want to spot problems in the data from the perspective of the process owner for whom you are performing the analysis (you can book a separate meeting with a data expert to walk through your data questions later). Ideally, your domain expert has access to the operational system during the session, so that you can look up individual cases together if needed.

To organize the data validation session with the domain expert, you can do the following:

You may find that the domain expert brings up questions about the process that are relevant for the analysis itself. This is great and you should write them down, but do not get side-tracked by the analysis and steer the session back to your data quality questions to make sure you achieve the goal of this meeting: To validate the data quality and uncover any issues with the data that might need to be cleaned up.

After the validation session, follow-up on all of the discovered data problems and investigate them. Also, keep track which of your original process questions may be affected by the data quality issues that you found. Document the actions that you have taken, or intend to take, to fix them.
