odology for improving your organization's operations. lean six sigma's team-oriented approach has proven results in maximizing efficiency and dramatically improving profitability for businesses around the world. still wondering, “what is lean six sigma exactly?” read on for an in-depth dive into what it is, why it matters, and how to do it right. five principles of lean manufacturing 1. value. value is determined by what the customer considers to be important within a product or service, rather than what the individuals developing or delivering the product or service consider important. 2. value stream. the set of business activities and steps involved in creating and delivering products and services to the customer; it is the connection of the steps together rather than considering each step in isolation. 3. flow. the degree to which there is smooth uninterrupted flow of activities that add value to the customer, rather than waste and inefficiency …

operation, not just manufacturing. it is now used in literally all functions and all industries. six sigma was first developed at motorola during the late 1980s. the methodology was pioneered by bill smith, a quality engineer, whose goal was to improve the way the quality and measurement systems worked so as to eliminate errors. the motorola systems tolerated error rates that created too much scrap, rework, redundant testing and often customer dissatisfaction. the six sigma approach focused on identifying and eliminating anything that caused variation in the process. when the variation is gone, the process results can be precisely predicted – every time. by designing the system so that these precisely predictable results fall within the zone of acceptable performance from a customer perspective, process errors are eliminated. but the engineers at motorola went one step further. they knew from experience that many process changes were not effective because they …

sure the true root cause(s) is identified and not just a symptom. 4. improve. in this phase the possible changes to the process, product or service are assessed and a solution set of changes is designed and tested. this is to ensure the solution creates the desired effect and that the variation is reduced or eliminated. 5. control. in this phase the changes are implemented, the supporting systems are also updated and the process, product, or service is put under control – normally statistical process control – to ensure the solution is fully implemented in a sustainable manner and to identify if performance starts to degrade. the methodology of six sigma will work with any process, product or service that has a definable performance goal and measurable characteristics, because the methodology heavily relies on data. 2. similarities and differences. lean and six sigma have been combined because, although they are …

at typically will be implemented by a small cross-functional team. the duration of the project and the size of the team will depend upon the scope and scale of the process, product or service being analyzed for improvement. · both have migrated beyond the manufacturing operation and are now used for all functions and for all internally facing and externally facing processes. they are also used in all industries including industrial, consumer, government, education, and non-profits. · improvements based upon using either approach will normally both reduce waste and reduce variation. removing wasted steps and activities (muda) eliminates sources of variation, and removing variation eliminates wasted process capacity and steps associated with accommodating the variation (mura and muri). however, there are some differences in the two approaches. these differences do not create a conflict, rather they provide multiple paths that can be used to reach a similar destination. a lean …
