Using Value Stream Mapping As a Strategic Planning & Implementation Tool
1. Using Value Stream Mapping as
a Strategic Planning and
Implementation Tool
Frank Garcia
Director, Engineering Services
ADVENT DESIGN CORPORATION
2. Why Use VSM?
Identify areas for lean improvements
Train team members in use of lean
concepts
Integrated lean implementation plan
Long term planning
3. What We’ll Cover
What is VSM?
Basic Lean Concepts
Developing Value Stream Maps: Current
& Future State
Implementing VSMs
Using VSMs
4. Lean Manufacturing
Fundamental Principle of Lean Manufacturing
Any activity or action which does
not add value to the product is a
form of waste and must be
eliminated or minimized.
5. Definition of Value -Added
Value is added any time the product is physically
changed towards what the customer is intending
to purchase.
Value is also added when a service is provided
for which the customer is willing to pay (i.e.
design, engineering, etc.).
If we are not adding value, we are adding cost or
waste.
90% of lead time is non-value added!
6. Waste or Opportunities for
Improvement
Adds no value
Adds only cost and
time
Symptom rather than
cause
Points to problems in
value stream and
process
Need to address
causes
7. The EIGHT Wastes
Inventory (more than one piece flow)
Overproduction (more or sooner than needed)
Correction (inspection and rework)
Material Movement
Waiting
Motion
Non-Value Added Processing
Underutilized People
8. FLOW & PULL
Make the value-creating steps flow
Produce only what is needed
If a process is not completed correctly the first
time, it does not move down the line for
additional work
Eliminate re-work
9. Value Stream
The value stream is the set of all the
specific actions required to bring a
specific product (good or service) through
the critical management tasks of any
business:
Information Management
Transformation
10. Value Stream Map
An Assessment Tool
The value stream map follows the order path from
beginning to end and shows a visual
representation of every process in the order and
information flows
Shows how the shop floor or office currently
operates
Develops the foundation for the future state

13. Who Develops the VSM?
Team Approach?
Better understanding of process
& opportunities
Provides training in Lean
Concepts
Feel ownership of VSMs
Exchange of ideas
More open discussion
Takes more time
14. Who Develops the VSM?
Engineer Collects Data and Drafts
VSM?
Takes less time
Can be done with Management
Team
Can train on lean concepts & get buy in
Less ownership by team and operators
Less exchange of ideas within the company
15. Who Develops the VSM?
Depends on the company culture and
preference
How much time can be devoted?
Team Approach is most effective!
16. What Tools to Use to Make the VSM?
Use Excel or Visio?
Hand draw?
Use AUTOCAD?
17. What Tools to Use to Make the VSM?
Use Excel or Visio
• Requires program
knowledge
• Easy to change
• Can use templates
• Easy to share &
Hand drawn e-mail
• Quick • Easy to present
• Easy for teams
• Difficult to change & copy
• Harder to present Use AUTOCAD?
FORGET IT!

22. Future State Questions
What is the takt time?
Will we build to shipping or to a supermarket?
Where can we use continuous flow? (Single Piece vs Batch)
Where do we have to use supermarket pull system?
At what single point in the production chain do we trigger
production?
How do we level the production mix at the pacemaker
process?
SUPPORTING IMPROVEMENTS
What process improvements will be necessary?
(e.g. uptime, changeover, training)
23. TAKT Time
Synchronizes pace of assembly
to match pace of sales.
Rate for assembling a product
based on sales rate.
TAKT = Effective Working Time per Shift
