Definitions
Process Mapping is a hierarchical method for displaying
processes that illustrates how a product or transaction is processed.
is a visual representation of the work-flow either within a process - or an image of the whole operation.
should allow people unfamiliar with the process to understand the interaction of causes during the work-flow.

Definitions (cont’d)
Value stream mapping is a tool that helps you to see and
understand the flow of material and information as a product or service makes its way through the value stream.
is typically used in Lean.http://www.isixsigma.com/dictionary/Value_Stream_Mapping-413.htm 4/20/2009

Process Mapping vs. Value Stream Mapping
Value Stream Mapping
1. gathers and displays a far broader range of information than a typical process map.
2. tends to be at a higher level (5-10 boxes) than many process maps.
3. tends to be used at a broader level, i.e. from receiving of raw material to delivery of finished goods.
4. tends to be used to identify where to focus future projects, subprojects, and/or kaizen events

Processing Time vs. Lead Time
Lead time:Period of time between the initiation and the completion of any process
Processing time:Actual amount of time spent working on a product or service.
Note: Lead time can easily be reduced by eliminating interfaces, whereas reducing processing time requires usually investments in better equipment and training.

Process Mapping Project
Conduct Workshops Cross-functional team Max. 1.5 hours
Start with “GRCA” forms (see example) Create cross-functional Process Flow Chart(s)
Identify number of interfaces Collect processing time and lead time Identify Number of Products/Services (m/d/hr)
Helpful but not always required

Success Factors
1. Management support
2. Willingness for change
3. Problem Solving Eliminate the cause of problems so they do not recur Yield for 80% and make changes as needed
4. Documentation Plain language, easy to read Easy accessible
5. Follow up Auditing Continuous improvement
