Value Stream Mapping 
1
Value Stream Mapping 
• A tool originally used by the Toyota Production 
System experts to study processes 
• Developed and refined by John Shook and Mike 
Rother 
• Used in manufacturing, engineering and 
administrative offices by lean experts to improve 
business processes
Value Stream Mapping Definition 
– Special type of flow chart that uses 
symbols known as "the language of Lean" 
to depict and improve the flow of 
inventory and information.

What is a Value Stream? 
A value stream involves all the 
steps, both value added and 
non value added, required to 
complete a product or service 
from beginning to end

PURPOSE : 
 Understand the role value stream mapping plays 
in continuous improvement 
 Draw a current-state map 
 Draw a future-state map 
 Develop an implementation plan 
Getting Started
Using the Value Stream Mapping Tool 
Understanding how things 
currently operate. This is 
the foundation for the 
future state. 
Scoping the 
Value Stream 
Designing a lean flow through 
the enterprise. 
Current state

Future state 
drawing 
Determine the Value 
Stream to be improved 
Planning and The goal of mapping! 
Implementation
Advantage of Value Stream Mapping & 
Analysis 
• 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 an implementation plan for improvements 
“If you can’t describe what you are doing as a process, 
you don’t know what you’re doing.” W. Edwards Deming

A SIMPLE EXAMPLE………….. 
Info: Location of stapler Info: Where to place staple 
Pick Up Paper Walk to Stapler Staple Paper 
Time: 1 sec. 
Distance: 0 
Walk to Desk Put Down Paper 
Time: 5 sec. 
Distance: 20 ft. 
Time: 5 sec. 
Distance: 20 ft. 
Time: 2 sec. 
Distance: 0 
Time: 1 sec. 
Distance: 0 
Total Time: 14 sec. 
Total Dist: 40 ft. 
Value Added Time: 4 sec. 
Value Added Dist: 0 
Value Added Time: 28%

Plan and 
Implementation 
Determining how production 
currently operates. 
Material and Information flows 
Draw using VSM icons 
Start with the “door to door” flow 
Walk the production lines and get actuals 
No standard times 
Draw by hand, with pencil 
Foundation for the Future Site
15 
TAKT Time 
TAKT Time 
Match assembly pace to pace of orders. 
Rate for assembling based on orders rate. 
Work Time per Shift 
TAKT Time = 
Customer Requirement per Shift 
27,600 sec 
460 pieces 
= 60 seconds

Implementation 
Designing a LEAN Flow 
The power behind Value Stream Mapping is you 
always need a future state! 
Keep Updating. Use pencil! 
Material and Information flows 
Basis for your Work Plan – like a “blueprint” 
Begin by drawing on Current State 
1st iteration assumes existing steps & equipment 
Can move equipment, combine, take out 
conveyors, make minor purchases etc. 
But, there is a Problem!
