Description

Introduction into Process Mapping and Value Stream Mapping: Discuss differences and applications of the two methods.Describe a successful approach of a process mapping project.

Learning Objectives

Learn how to map a business process Identify weaknesses and problem

areas of the process Learn about possible problem

resolutions

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.

(HR Lean Project)

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

Example

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
