L6 - Lecture 19: Value Stream Mapping

Front 1

What are the 5 steps of Lean Implementation?

Back 1

1) Specify value
2) Map the Value Stream
3) Create flow
4) Pull
5) Pursue perfection

Front 2

Give detail on "Mapping the Value Stream"

Back 2

1) Helps identify all the specific activities in a value stream for a product family
2) Gives ability to "see the flow" & design future-state value streams

Front 3

How does the mapping process work?

Back 3

.

Front 4

What can be included in the mapping icon, Data Box?

Back 4

1) Cycle time
2) Changeover time
3) Process uptime (reliability)
4) # of operators / machines
5) Number of shifts
6) Working time (minus breaks)
7) Batch sizes

Front 5

Define Cycle Time

Back 5

How often a part or product is completed by a process, or the time it takes an operator to go through all of his/her work elements before repeating them

Front 6

Define Value Added Time

Back 6

Time for those activities that actually transform the product in a way the customer is willing to pay for

Front 7

Define Lead Time

Back 7

The time it takes one piece to move all the way through a process or value stream, from start to finish (envision timing a marked part as it moves from beginning to end)

Front 8

What is a Future State Map?

Back 8

1) Basis for your Implementation Plan
2) Begin by drawing on current state
3) First draft assumes existing steps & equipment
4) The power behind Value Stream Mapping
