Lean Manufacturing

Lean manufacturing is a manufacturing strategy that aggressively attempts to minimize waste in a system, where waste is defined as anything which does not create value to the end customer.

Legacy Systems (or Applications)

Legacy systems refer in general, to computer programs written specifically for a single organizational function, before the days of integrated software or ERP systems. Legacy systems tend to be highly customized, somewhat difficult to maintain, and are strongest where administrative labor was replaced: payroll, accounts payable, accounts receivable, order entry, etc. Legacy systems almost always have to talk to each other by means of limited data interfaces.

LIFO is an acronym for "Last In First Out", normally associated with an inventory strategy. LIFO means that you always consume your most recently purchased raw materials first (which requires that the raw materials can be stored indefinitely without deteriorating). The normal advantages of LIFO are (a) the inventory is often easier to get to (tends to be toward the front of an aisle or storage bay and (b) it tends to reduce the financial value of inventory (inflationary pressures drive prices up, so directionally, older raw materials are cheaper than current raw materials).


The degree to which assets can be turned rapidly into cash. Financial instruments, like stock, can be turned into cash in a few minutes, and are more liquid than inventory, which can be turned into cash in a few days, which is more liquid than raw materials, which can be turned into cash in a few weeks, and so on.
