Purpose – The purpose of this paper is to describe new methods to manage variation in complex manufacturing process chains and to show synergies between the variation risk management (VRM) and six-sigma approaches. Design/methodology/approach – The research methodology was experimental prototyping ...
Six Sigma is a widely used moniker to represent a set of design and manufacturing techniques, the aggregate of which should effectively improve quality and lower cost. Six Sigma implies that six standard deviations of performance should be maintained between the performance mean and the closest speci...
Planned variation, like that in an experiment, is a process improvement strategy. Unplanned variation, however, is nearly always bad. Two types of variation concern a Six Sigma team: Common cause variation – All processes have common cause variation. This variation, also known as noise, is a...
All well trained Six Sigma professionals know that variation is the root of all evil – at least with respect to the customer experience. I understand this all too well myself. I usually experience it when it is least appreciated – in the early morning. Many nights I find myself up late...
There is a widespread phenomenon in designing chips that new effects creep up on you. First they are so small you can ignore them. Then you can add a little pessimism to your timing budget or whatever gets affected. But eventually the effects go from sec
"I've got the assignment set up so that they're using the tools in the same order they would use them in a real business process in a real factory if they're actually doing a quality improvement project, if they're actually working, for example, on a Six Sigma process improvement ...
Standardization is key to ensuring that variation is kept to a minimum, and it should be no surprise that it plays such a major role in Six Sigma in general. You’ll find that every talk about Six Sigma puts a lot of emphasis on the topic of standardization, and this can apply to all...
For instance, Six-rowed 1 (VRS1) and Non-brittle rachis 1 (btr1) or Non-brittle rachis 2 (btr2) genes in barley have clear impact on spike architecture phenotype as a consequence of domestication [4,5]. During domestication, loss of function in VRS1 gene converted the two-rowed barley...
