Value Stream Mapping
Follow a “products” production path from beginning
to end, and draw a visual representation of every
process in the material & information flow.
Then, draw (using icons) a “future state” map of
how value should flow.

Current State Mapping
1. Mapping the current state :
• Review the basic processing steps and calculate the takt time in
your team’s breakout room.
• Everyone draw while on the shop floor.
Be sure to draw both the material & information flows.
• Always introduce yourself to operators and tell them what you are
doing : “Drawing the total factory flow as part of a training
session.’ Show them your drawings.
• Select a scribe and combine your drawings into one current state
map (in team area).
• Calculate total lead time versus processing time.
• Make an overhead transparency of the map and select presenters.

2. Presenting your
• All team members go up front with presenter. State the product
family and takt.
• Present from your overhead transparency. (Less than 5 minutes.)
• Start with the customer and information flow into the facility.
• State the lead time vs. processing time.
• What are the problems you see? Where did you find push and
overproduction ?
• Share any future state thoughts you have so far.

Adding Value In Totality !!
In looking at the almost completed map you can now see the basic pattern of all value stream maps, specifically a flow of physical product from left to right across the lower portion of the map and a flow of information about this product from right to left across the upper portion. You can also see how a value stream map differs from the typical visual tool used in operations analysis – the facility layout. The value stream map makes the welter of events shown in the plant layout suddenly comprehensible from the perspective of a product’s value stream and its customer.
With the data from observation of current operations drawn or recorded on the map, we can summarize the current condition of this value stream. Draw a timeline under the process boxes and inventory triangles to compile the production lead time, which is the time it takes one part to make its way through the shop floor, beginning with arrival as raw material through to shipment to the customer.
Note
The shorter your production lead time, the shorter the time between paying for raw material and getting paid for product made from those materials. A shorter production lead time will lead to an increase in the number of inventory turns, a measure with which you may be more familiar.
Lead times (in days) for each inventory triangle are calculated as follows : Inventory quantity divided by the daily customer requirement. By adding the lead times through each process and through each inventory triangle in the material flow, we can arrive at a good estimate of total production lead time. At Acme Stamping this number is 23.6 days. (For maps with multiple upstream flows, use the longest time path to compute total lead time.)
Now add up only the value-adding times or the processing times, for each process in the value stream. Comparing value-added or processing times to total lead time should give you quite a shock. At Acme Stamping the total processing time involved in making one piece is only 188 seconds, whereas that piece takes 23.6 days to make its way through the plant.
Note
At Acme Stamping the lead time through a process and the cycle time are the same. In many cases however, the lead time for one part to move through a process is longer than the cycle time. You can draw both lead time through a process and the value-adding time as follows :
2 hrs. - (Lead time through the process)
40 Seconds - (Value-adding time)
