Overview
  • VSM Key Tool in Continuous Improvement
  • Understanding What the Customer Values
  • Muda
  • Current State
  • Future State

3
VSM
  • VSM Key Tool in Continuous Improvement
  • Graphical Representation of Value Stream
  • Flow of Materials and Information Through
    Transformation to Deliver Product/Service to
    Customer
  • VSM has an Enterprise Focus rather than a
    Functional Focus

4
Five Principles of Lean
  • 1.) Value
  • 2.) The Value Stream
  • 3.) Flow
  • 4.) Pull
  • 5.) Perfection

5
Muda
  • Waste
  • Type-1 muda
  • non-value added but deemed necessary
  • Type-2 muda
  • non-value added and unnecessary

6
VSM Current State
  • Identify VSM Team
  • Leader
  • Assembled Team
  • Data Collection
  • Identify Major Process Steps
  • Quantify the Process

7
VSM Current State (cont.)
  • Decide Value added and Non-Value Added Activities
  • Estimate Times
  • Sum the Individual Times
  • Review Process
  • Quantify Overall Lead Times

8
VSM Current State (cont.)
  • Determine the Information Flow
  • Validate the VSM

9
VSM Information Typically Collected for Current
State
  • The end customers requirements
  • Customers schedules
  • Cycle time or processing time
  • Changeover time
  • Reliability of equipment
  • Quality yield information

10
VSM Information Typically Collected for Current
State (cont.)
  • Quantities (batch sizes)
  • Number of operators shifts
  • Hard copies of information
  • Inventory levels
  • Queue or waiting time
  • Information flow

VSM Future State
  • Analyze Your Current State VSM
  • Start With Your Customers View
  • Identify Issues in the Value Stream that Affect
    the Customer
  • Quantify Customer Demand Rate (takt Time)
  • Identify Where Flow is Less than Ideal

16
VSM Future State (cont.)
  • Blockages Can be Traced to Muda
  • Remove Blockages
  • Look for Muda, Mura, and Muri
  • Consider two future views
  • Future State
  • Incremental Improvement State

17
VSM Future State (cont.)
  • Update the Current State VSM to Reflect the New
    Current State
  • Compare the New Current State to the Future State
  • Start Mapping Again
