Value stream mapping (VSM), Purpose of value stream mapping, Current state mapping, Future state mapping, Implementation of VSM

Value stream mapping (VSM)

A series of steps that must be performed in the proper sequence to create value for a customer & required to bring a product from order to delivery

• The entire set of activities running from raw material to finished product for a specific product or product family
• The complete value stream includes information, & product or material flow
• Includes all steps; value-added & non value-added (avoidable & unavoidable)

Whenever there is a product for a customer, there is a value stream. The Challenge lies in seeing it

• Helps to visualize more than just the process level
• Allows to see the sources of waste
• Define key leverage points for improvements
• Displays linkage between information & material flow

Purpose of value stream mapping

• Develop a common understanding of the current process

• The relationship of process steps

• A true picture of the process

• Create a baseline to measure improvements against
• Define a vision of the future process
• Establish common leadership objectives
• Identify opportunities for improvement
• Design implementation plan for improvements

Mapping process

Product family

• Gather preparatory information

• Document case for change, define the scope (start & end of process), identify the requirements, and Review/establish measurements

• Set logistics for event

• Participants, Location, Materials, Meals/Refreshments Etc.

Current state mapping

• Observe & gather data

• Walk the value stream (see the actual work place), Follow & make notes about “item” & information flow, Gather data for each step in the flow

• Map the flow of items & information
• Add data & issues
• Use the Handout Data Sheet (pencil & small Post-it notes on 11” x 17” paper)
• Remember “Always start with the Customer”

Future state mapping

Discuss the ideal state & develop the future state map

Work plan & implementation

• Develop action plans & cadence tracking

• Build draft time line for implementation

• Communication & training as required
• Implement improvements

• Conduct Workshops, events, projects, bursts per implementation plan

• Achieve value stream objectives
• Create an environment of continuous improvement
