5项法则被定义成为规定的格式来指导改善的目标.该法则集聚了六西格玛和精益的精华.5 Laws of Lean Six Sigma have been formulated to provide direction to improvement efforts. The laws are a conglomeration of Key Ideas of Six Sigma and Lean.
法则1:市场法则.客户对品质的要求决定了品质的最高标准和必须改善的第一目标.ROIC(投资回报比)和净利润可用来衡量努力的结果.这条法则是所有其他法 则建立的基础.Law 0: The Law of the Market - Customer Critical to Quality defines quality and is the highest priority for improvement, followed by ROIC (Return On Invested Capital) and Net Present value. It is called the Zeroth law as it is the base on which others are built.
法 则2: 灵活法则.所有流程的效率改进最终是最大限度地增加了该流程的灵活和应变能力.Law 1: The Law of Flexibility - The velocity of any process is proportional to the flexibility of the process.
法则3:28法则.80%的流程的低效率是由流程中20%的无效动作引起的.此项符合柏拉图法则.Law 2: The Law of Focus - 20% of the activities in a process cause 80% of the delay. (Related to Pareto Principle)
法则4:效率法则.任何流程的效率通常都和该流程中的浪费成反比.此项又称为缩小法则.WIP的Law 3:The Law of Velocity - The velocity of any process is inversely proportional to the amount of WIP. This is also called Little's Law.
法则5:任何产品或服务的复杂化只能导致无价值的,高成本的,流程浪费.表现为低西格玛值,品质低劣,或流程效率低下.Law 4: The complexity of the service or product offering adds more non-value, costs and WIP than either poor quality (low Sigma) or slow speed (un-Lean) process problems. |
