Using Process Mining Capabilitiesin Lean Six Sigma Projects
Process Performance Issues
•Processes don’t deliver on time
•Processes are expensive
•Processes are complex
Business Process Mining © 2009
Processes not well understood
•No adequate documentation
•No structure to process components
•Knowledge held by individuals

Lean Six Sigma Project?Before you start – look at Process Mining capabilities
•Need Process Discovery
•Need Statistical Data
•Need Semantic Data

The actual process
Process Discovery
Business Process Mining © 2009
The planned process
Statistical Data
Business Process Mining © 2009
The process is in control
Semantic Data
Business Process Mining © 2009
How the organisation views its human resources
Semantic Data
Business Process Mining © 2009
How users actually work together on activities
Semantic Data

Analyse performance by individual & team
Semantic Data
Business Process Mining © 2009
Knowledge held by IT but not ‘known’ by the process
Semantic Data

Abstractionsallow clarity& simplicity

Analyse performance by task abstraction
Look for Sources of “Waste”
•Waiting
•Overproduction
•Transportation
•Double Processing
Business Process Mining © 2009
Performance Analysis reveals bottlenecks and wait times (individual & global)
Compare actual completeversus planned process and look for duplicate paths
Look at process flow andlocation of work & resources
Look at process flow and social network analysis
Look for Sources of “Waste”

•Motion
•Rework
•Inventory
•Intellect
Review “Role Hierarchy” to determine if resources are conveniently located to each other
Use Linear Temporal Logic (LTL) to determine the amount of rework
Use arrival rates and cycle times to minimise work-in-progress
Use social network analysis to determine domain experts
