Creating a Value Stream Plan
Lean Enterprise Academy www.leanuk.org
Objectives of Mapping Extended
Value Streams
Seeing the Whole Extended Value Stream
Raise consciousness in every firm & function touching the
value stream of the enormous waste of time, effort &
movement
Typical current state 9 out of 10 steps & 99% of elapsed time are
wasted
Raise consciousness in every firm & function of the effect of its
actions on every other firm & function touching the value
stream
Learn how a value stream team with representatives from
every firm can envision a series of Future States & an Ideal
State for their shared value stream
Learn how the team can progressively implement:
A Future State 1 in which smooth, levelled pull & flow are
introduced within every facility touching the value stream
A Future State 2 in which smooth, levelled pull & frequent
replenishment loops are introduced between every facility touching
the value stream (eliminating warehousing & cross docking in the
process)
An Ideal State (providing a North Star for collectively steering
towards the perfect value stream with zero waste) by compressing
the value stream & introducing right-sized technologies
Learn how value stream teams can share costs & gains to
create win-win-win outcomes for every value stream
participant
Lean Enterprise Academy www.leanuk.org
Your Check List
Is top management willing to lead lean?
Is there a common language across the
whole organisation for seeing processes
and for root cause problem solving?
Is there a common way to manage lean
projects – and to sustain the results?
Is someone responsible for
reconfiguring each product value stream
through the facility and beyond?
Is there an active policy deployment
process based on value stream plans to
prioritise and resource them?

What is a Plan?
“The documented results of the planning

Consists of: who, why, what, where,

What is a Lean Project
Plan?
All the above
A Gantt chart with bookends (goals,

Follows the PDCA process
Is a contract - a commitment to actually
accomplish something by a specific
time
Ref: John Shook: Leadership for Value Stream Management
Lean Enterprise Academy www.leanuk.org
A Format for Planning &
proposing - A3
A3 because it’s done on A3 paper
Originally used in Quality circles
Power lies in the process & thinking
behind it
An A3 lays out an entire plan (large or
small) on one piece of paper
It should be visual & concise
It should tell a story - upper left to
lower right that everyone can
understand
Acme Stamping Steering Bracket Value Stream Improvement
Background
Acme supplies stamped steel steering brackets (LH & RH) to State
Street Assembly. The product goes through 5 manufacturing processes &
shipping.
The customer uses 18,400 pcs/month & requires daily shipments in
pallets of 10 trays of 20 brackets. A pallet is either all RH or LH.
Current Situation
Lead time for steering bracket from coil steel to shipment = 23.6
days.
Of 23.6 days, only 188 seconds are spent making a bracket.
Large inventories of material between each process.
Long changeover times, downtime in welding.

Recommendations
Create continuous flow through weld & assembly
Establish TAKT time . Base the pace of work through weld & assembly
on customer demand.
Set new weld - assembly cell as pacemaker for entire value stream.
Establish EPE_ build schedule for stamping based on actual use of
pacemaker cell & pull steel coils from supplier based on actual usage by
stamping.
Improve uptime in weld.
Establish material handling routes for frequent withdrawal & delivery.
Establish new production instruction system with Levelling Box.
Analysis
Each process operates as isolated islands, disconnected from the
customer.
Push system, material builds up between each process.
Each process builds according to its own operating constraints
(changeover, downtime etc.)
Plans based on 90 & 30 day forecasts from customer. Weekly
schedule for each department. System is frequently overridden to make
delivery.
Goals
Improve profitability of steering bracket value stream.
Reduce lead time - 23.6 days to 4.5 days.
Reduce inventories:
Stamping 7.6 days to 1 day.
Welding 6.5 days to 0 days.
Shipping 4.5 days to 2 days.

Weekly schedule for each department. System is frequently overridden to make delivery. Goals Improve profitability of steering bracket value stream. Reduce lead time - 23.6 days to 4.5 days. Reduce inventories: Stamping 7.6 days to 1 day. Welding 6.5 days to 0 days. Shipping 4.5 days to 2 days. Recommendations Create continuous flow through weld & assembly Establish TAKT time . Base the pace of work through weld & assembly on customer demand. Set new weld - assembly cell as pacemaker for entire value stream. Establish EPE_ build schedule for stamping based on actual use of pacemaker cell & pull steel coils from supplier based on actual usage by stamping. Improve uptime in weld. Establish material handling routes for frequent withdrawal & delivery. Establish new production instruction system with Levelling Box. Follow Up Reviews & involvement of related departments TBD. Other functions: Production Control Material Handling, Purchasing, Maintenance, Human Resources, Finance.

    Lean Enterprise Academywww.leanuk.org Your Check List Is top management willing to lead lean? Is there a common language across the whole organisation for seeing processes and for root cause problem solving? Is there a common way to manage lean projects – and to sustain the results? Is someone responsible for reconfiguring each product value stream through the facility and beyond? Is there an active policy deployment process based on value stream plans to prioritise and resource them?
