Implementing a Mixed Model Kanban System: The Lean Replenishment Technique for Pull Production

The Requirements Study Worksheet is where the team characterizes the level of demand for each golf club head model. Relative to one another, golf club heads are either "A" items, "B" items, or "C" items. "A" items are frequently ordered, high-volume items. "B" items are ordered somewhat frequently and are medium volume. "C" items are infrequently ordered or low-volume items.
| Note | In the case of special order items, (at Emca Golf, the head machining resource produces none) you would classify them as "D" items and assign single use kanban cards for their production. |
The Emca kanban implementation team agreed upon the following parameters in establishing their A-B-C-D boundaries for the heads:
| Classification | Daily Demand |
|---|---|
| A | ?76 |
| B | ?75 and ?51 |
| C | ?50 |
Applying the above parameters, the team designated the various club heads as follows.
