I'm no expert but here's my two cents. In general there's pallet pick, case/carton pick and each/piece pick. The choice amongst different units of pick depends on the ordering quantity.

Agreed with Sarah. The picking strategy suitable for the operations is dependent on the quantity/type of inventory being picked.

Additionally, the picking team can explore wave picking, zone picking or individual order picking (just to name a few).

Will be good if someone can analyze how the orders are dropped and how they are fulfilled currently.

Aside from the picking strategy, the storage method should also be a derivative of the order profile.

The first is Carton Pick and the 2n is Parallel Picking
In a parallel picking strategy, each worker is still assigned a zone; but all zones are picking the same orders in parallel
