We invite contributions. A nice thing about bucket brigades is that you can try it out on a slow day. You need no special equipment. We have found workers pick up the idea quickly. In general, if you are currently using zone-picking to progressively assemble orders, you should consider changing to bucket brigades.
Bucket brigades work best when pick-density is high and the items to be picked are small.
Finally, to make bucket brigades most productive you should commit to building and sustaining a team-oriented work environment. Because it fails to balance the work as well as bucket brigades and therefore is less productive. Furthermore, because it is based on only a static idea of balance, it requires constant management attention to re-balance work during the day. It is always wrong because workers are not standard and the model cannot foresee the inevitable disruptions of the day. In contrast, bucket brigades spontaneously and dynamically reallocate work based on how long it actually took specific workers to pick specific orders.
