ANSWER

Process Mining is a data-driven discipline that extracts digital footprints from the event logs of enterprise systems (ERP, CRM, BPM, ticketing, IoT, etc.) and automatically reconstructs how work actually flows through an organization. Unlike workshop-based mapping that relies on interviews and sticky notes, it reveals the real sequences, variants, wait times, and exceptions recorded by time-stamped transactions.

Process Mining turns system exhaust into x-ray vision for business processes, empowering analysts to diagnose, quantify, and continuously manage improvement opportunities with scientific precision.

 

Three Core Capabilities

  1. Discovery – builds a visual as-is model from raw logs, highlighting the most common path and every deviation.
  2. Conformance – compares that empirical model to a reference design or policy to spot violations, rework loops, and compliance risk.
  3. Enhancement – enriches the model with performance data (cycle time, cost, carbon, customer sentiment) so improvement scenarios can be simulated.
 

How It Works: Ingest logsidentify case ID, activity, timestampalgorithmically create process graphoverlay metricsdrill down by variant, root cause, or personaexport insights to BI or automation tools.

Common Metrics Reported: Lead and touch time, waiting time, throughput, first-pass yield, variation count, compliance score, automation potential.

Tools: Commercial platforms (Celonis, UiPath Process Mining, Apromore, Minit) and open-source libraries (ProM, PM4Py) ingest logs from SAP, ServiceNow, Salesforce, or custom databases via connectors or SQL.

 

Why Business / Systems Analysts Use It

  • Cuts through hearsay: replaces “I think we do X” with provable facts.
  • Quantifies waste: idle time, rework, ping-pong hand-offs, and variant sprawl are measured in minutes and dollars.
  • Builds bulletproof business cases: simulation shows how removing one approval or adding a bot affects lead time and capacity.
  • Feeds requirements: the mined “happy path” and exceptions translate directly into user stories, SLAs, and test scenarios.
  • Supports continual monitoring: dashboards alert stakeholders when the live process drifts from the improved design.
 

Example

A telecom analyzed 12 million trouble-ticket events. Mining revealed that 27 % of tickets detoured back to Level-1 support after Level-2 touched them, adding 2.1 days per case. Automating ticket triage and adding a knowledge-base prompt cut rework to 4 % and saved £3 M annually—numbers the analyst could present with confidence because they came straight from the logs.

Do your homework prior to the business analysis interview!

Having an idea of the type of questions you might be asked during a business analyst interview will not only give you confidence but it will also help you to formulate your thoughts and to be better prepared to answer the interview questions you might get during the interview for a business analyst position.  Of course, just memorizing a list of business analyst interview questions will not make you a great business analyst but it might just help you get that next job.
