The Benefits of Process Mining, and When You Actually Get Them

The benefits of process mining come from one thing: an accurate picture of how a process really runs, built from the data your systems already record. With that picture, organisations find bottlenecks with evidence instead of opinion, check compliance on every transaction instead of a sample, choose what to automate on facts, and measure whether a change worked. Whether those benefits appear depends less on the software than on the data underneath it and on who acts on what it shows.

In Deloitte's Global Process Mining Survey 2025, based on more than 120 respondents, 80 percent agreed or strongly agreed that process mining delivers added value. The same survey also shows where the value stalls, starting with management attention.

The benefits of process mining, in short

Process mining reads the event logs in systems such as SAP, Oracle or Salesforce and reconstructs every path a process actually takes. The benefits follow from that reconstruction:

• Visibility: the real process, with all its variants, instead of the documented one
• Speed: bottlenecks and waiting time located to the step and the team
• Control: conformance checked on every case
• Better automation choices: automate what is frequent and stable, fix what is broken first
• Lower cost: less rework, fewer manual touches, fewer late payments
• Customer impact: shorter cycle times and more reliable delivery
• Continuous monitoring: the picture stays current, so improvements can be measured

Seven benefits, and what each one depends on

1. Visibility: you see the process as it runs, not as it was drawn

Every process has a documented version and a real one. Process mining shows the real one, including the variants nobody planned: the order that is changed three times, the invoice that is approved twice, the case that bounces between teams. This is the benefit everything else rests on.

Depends on: a case identifier that holds across systems. If the quote, the sales order and the invoice cannot be linked to the same piece of work, the picture breaks into fragments.

2. Speed: bottlenecks are found with evidence

Instead of a workshop where each team points at the next, process mining shows where time is actually lost, how often, and in which variant. A delay that everyone blamed on approvals may turn out to sit in a handover nobody mentioned.

Depends on: timestamps that mean what you think they mean. A step logged at the end of the day, rather than when it happened, hides the real waiting time.

3. Control: compliance is checked on every transaction

Conformance checking compares how each case ran against how it was supposed to run. Instead of testing a sample, auditors and controllers can see every case that skipped an approval, broke a payment rule or bypassed three-way matching.

Depends on: a current, agreed process model to check against. Conformance against an outdated model measures the wrong thing.

4. Better automation choices: automation goes where it pays

Process mining shows which steps are frequent, repetitive and stable, which makes them good automation candidates, and which are messy and need fixing first. Automating a broken variant only makes it fail faster.

Depends on: knowing why a step is manual. The event log shows that a person touched the case, not what they had to read or decide.

5. Lower cost: rework and manual touches become countable

Rework, duplicate payments, missed early-payment discounts and manual touches all have a price. Process mining makes them countable, which is what turns an improvement idea into a business case.

Depends on: someone with the authority to change the process. A precisely measured cost that nobody owns stays a cost.

6. Customer impact: shorter cycle times and fewer late deliveries

Shorter order cycle times, fewer late deliveries and faster answers are the customer-facing result of the benefits above. In the Deloitte survey, 28 percent of respondents expect process mining to improve customer satisfaction.

Depends on: seeing the customer-facing steps. Many start with an email, which leaves no event in the log.

7. Continuous monitoring: improvement becomes measurable

Because the picture is rebuilt from live data, you can see whether a change worked, and catch the moment a process starts to drift again. In Deloitte's survey, 41 percent of respondents expect process mining to support process monitoring.

Depends on: an owner and a review rhythm. Run as a one-off project, the picture goes stale.

What organisations expect, and what they report

Deloitte's 2025 survey shows how expectations have shifted since its 2021 edition:

• Process improvement: 61 percent of respondents, down from 77 percent in 2021
• Cost savings: 59 percent, up from 46 percent
• Process transparency: 51 percent
• Process monitoring: 41 percent
• Identifying automation opportunities: 38 percent
• Worker productivity: 36 percent
• Customer satisfaction: 28 percent

Cost savings now almost match process improvement as an expectation: 59 percent against 61 percent. Process mining is increasingly expected to pay for itself in money, not only in insight. Deloitte separates the two: analytical value, such as transparency and monitoring, and monetary value, such as cost savings and higher stakeholder satisfaction.

Satisfaction is rising too. Almost half of respondents, 49 percent, said their satisfaction with process mining had improved over the previous twelve months.

Where the benefits stall

The survey and practitioners point to four obstacles.

Leadership attention. Lack of management attention was cited by 41 percent of respondents, up from 26 percent in 2021. Where process mining is in use, 55 percent report that the C-suite actively supports it. Findings without a sponsor rarely become changes.

Data that does not connect. BPM consultant Hanneke Loefs-Mos, quoted by Process Excellence Network, names disconnected identifiers as the classic problem: quote numbers that do not link to sales orders, sales orders that do not link to invoices. Each system is accurate on its own; together they do not describe one case. How to choose process mining software covers how to test this before buying anything.

Turning insight into action. Process Excellence Network's summary of the survey lists translating insights into measurable outcomes among the main obstacles. A dashboard that shows the problem is the start of the work, not the end of it.

The part of the process no system records. Many expensive processes start with a message: an order by email, a change request, a complaint, a supplier's revised schedule. The ERP records the outcome once someone has typed it in. The reading, deciding and chasing before that leave no event, so process mining sees a gap between two timestamps and cannot say what happened inside it. That is why process intelligence needs to start in the inbox for any process that runs through shared mailboxes.

How to measure the benefits of process mining

Measure before you change anything. Pick three or four of these numbers that the process owner already cares about, and record their current value:

• Cycle time, from the first event to the last, and for the slowest 10 percent of cases
• Touches per case, the number of manual steps a case needs
• Rework rate, the share of cases that loop back
• Conformance rate, the share of cases that follow the approved path
• A money figure, such as late-payment cost, missed discounts or cost per case

Then change one thing at a time and compare the same numbers on the same data. The same discipline applies after automation. After automating email intake, Tekst customer Dossche Mills measured more than 95 percent classification accuracy on order and complaint emails and €100,000 in net annual savings.

Process mining delivers most where the data connects, someone owns the outcome, and the analysis covers the whole process, including the part that starts in the inbox. For concrete examples by function, see process mining use cases and examples.
