Ch. 16 Lean Production is an integrated set of activities designed to achieve production using minimal inventories of raw materials‚ work-in-process‚ and finished goods. Based on the JIT logic: nothing is produced until it is needed (Item arrive at the next stage of production “just in time”) JIT means producing what is needed when needed and no more; Major goal: Elimination of all wastes. Waste is defined as anything that does not add value from the customer’s perspective. E.g.‚ Waste from overproduction

Biology- Maintaining a Balance Summary 1. Most organisms are active in a limited temperature range 1. identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates Enzymes are proteins which act as catalysts in living things (they lower the amount of energy needed for a reaction‚ therefore increasing rate of reaction). Enzymes speed up reactions but are not used up by them. Enzymes catalyze only one
