Value Stream Mapping
Map your value stream and identify improvement opportunities
What is VSM?
Value Stream Mapping is a lean method for visualising every step in a process — from start to finish. It reveals where value is created, and where waste is hiding.
Purpose
To create a shared picture of the current state, identify bottlenecks and waste, and design an improved future state.
The 8 types of waste (TIMWOODS)
Transport
Unnecessary movement
Inventory
Excess stock
Motion
Unnecessary motion
Waiting
Waiting time
Overproduction
Too much, too early
Overprocessing
Unnecessary steps
Defects
Errors and rework
Skills
Untapped talent
