WarehousingThe storing (holding) of goods.

WasteIn Lean and Just-in-Time, any activity that does not add value to the good or service in the eyes of the consumer. Also, a by-product of shipping containers, environmental service activities, or food service process requiring management control. Waste production can be a significant challenge in the hospital setting and requires a coordinated effort of multiple departments.
Waste1) Any activity or process that does not add value to the goods or services required by the customer. Examples of waste include move time, counting inventory, inspection, the production of defective material, rework, etc. Waste is considered to cause increased cost, lead time and quality problems while not adding value, and may be created by vendors, personnel, equipment, incorrect process parameters and many other factors.

The WATCHMAN Device is intended for percutaneous, transcatheter closure of the left atrial appendage (LAA). Patients with non-valvular atrial fibrillation who are at increased risk for stroke and systemic embolism, are suitable for warfarin and seek a non-pharmacologic alternative to warfarin may be eligible for a WATCHMAN Device. By closing off the LAA, the risk of stroke may be reduced and, over time, patients may be able to stop taking warfarin.
Waterway use taxA per-gallon tax assessed barge carriers for use of the waterways.
Wave PickingA variation on zone picking where rather than orders moving from one zone to the next for picking, all zones are picked at the same time and the items are later sorted and consolidated into individual orders/shipments. Wave picking is the quickest method for picking multi item orders however the sorting and consolidation process can be tricky. Picking waves are often designed to isolate shipments to specific carriers, routes, etc. See also batch picking, zone picking A more general definition of wave picking would simply be a method where a group of orders is released to the warehouse for picking and the next group (wave) is not released until the first wave has processed through the pick area.
