Value Stream Mapping Definition
• Value Stream Mapping (VSM):
– Special type of flow chart that uses symbols
known as "the language of Lean" to depict
waste and improve the flow of inventory
and information.
• VSM follows a products production path
from beginning to end, and draw a visual
representation of every process in the
material information flows. Mapping the
value stream allows us to look at our
business from a different perspective, or
with ‘fresh’ eyes.
Value Stream Mapping Purpose
• Provide optimum value to the
customer
through a complete value
creation process
with minimum waste in:
– Design (concept to customer)
– Build (order to delivery)
– Sustain (in-use through life cycle
Value Stream Mapping Purpose• It helps us visualize more than just the process level-lets
us see from door to door (and beyond)
• It allows us to see the sources of waste.
• It shows linkage, or lack therefore, between the flow of
information and the flow of material- VSM is the only
tool to include critical information flow and much of lean
depends on how information flow is handled.
• It provides a common language and assists in clearly
communication future state ideas.
• It helps target improvement projects on the right
opportunities that will make a real difference to
performance and flow.
• VSM facilitates the selection of appropriate tools as
needed to archive future state vision.
• It provides a blueprint for implementation. Would you
build a new house without a blueprint.
• It ties together various lean concepts and techniques.
Why ?
• Many organizations pursuing “lean”
conversions
have realized that improvement events alone
are not enough
• Improvement events create localized
improvements, value stream mapping &
analysis
strengthens the gains by providing vision and
plans that connect all improvement activities
• Value stream mapping & analysis is a tool that
allows you to see waste, and plan to eliminate
it.
What Is Value?
• A capability provided to a customer
– of the highest quality,
– at the right time,
– at an appropriate price,
• as defined by the customer.
• "Value" is what the customer is buying.
• What do you currently do for the customer?
• What should you do for the customer?
• You must provide your customer with a good value
proposition.
• A value proposition offers:
• 1 Time
• 2 Quality
• 3 Cost
What Is ValueStream Analysis?
• Planning tool to optimize results of
eliminating waste
Current State VSM+Idea+Lean Basic+Future State
VSM
Where there is a value from your customers point of
view there is a value steam. The challenge lies in
identifying it.
1 On-time delivery improvement.
2 Productivity improvement.
3 Manufacturing lead time reduction.
4 Reduction in sales break – even point.
5 Finished goods inventory removed.
6 All obsolete machinery removed.
Value Steam Mapping Steps
• Select a product family: Identify the unit of
analysis.
• Current State Map: Gather data on your
material and information flow on the work
flow.
• Define Ideal State: Think of where you want
to go in an ideal situation. Making of a
perfect system.
• Future State Map: Draw a future State map
that uses the principal of flow and pull.
• Action Plan: Create an action plan to
implement the future state map you have
created.
What does the Value stream provides
• A visual tool to show how value flows to the
customer in your organization.
• A 2D representation of your value stream
map.
• A clear summary statement which helps
you to communicate a shared vision.
• Measurable goals.
• A continuous improvement plan.
• A system blueprint for how the value
proposition can be improved for the
customer.
• Understanding of how much production
time is value and non value.
What is Flow?
• "ITEMS" flow through a value stream
• – In manufacturing, materials are the items
• – In design & development, designs are the
items
• – In service, external customer needs are
the items
• In admin., internal customer needs are the
items
• Analysis begins with part of a total value
stream,
• That part of the value stream has
customers too
