Value Stream Map

Draw the flow of one product or service from the supplier to the customer: every step with its cycle time, changeover, uptime and yield, and the pieces waiting between the steps. The tool turns the piles into time, draws the map with its lead-time ladder, shows how little of the lead time is work, names the step above takt, and lets you draw the future state with a kaizen burst for each change.

1 · The value stream

Working minutes are the time the stream runs in a day, without breaks. Takt is that time divided by the demand, and a pile of one day's demand is one working day of waiting.

2 · Start from a template

Replaces the steps of the state you are drawing with the template's steps and typical times. Count the inventories yourself: they are the waits.

3 · Process steps

In the order of the flow. CT is the work time of one piece; with more operators the step releases a piece every CT ÷ operators. Between the steps, count the pieces waiting: the tool turns them into time through the demand.

No steps yet. Choose a template, add a step, or .
