In this part . . .
Here we look to see how well the work gets done. Are you meeting your customers’ requirements in the most effective and efficient way? Managing by fact is a key principle in Lean Six Sigma, so having good data is vital. Data collection is a process in itself, and we present a five-step approach to ensuring you have an appropriate plan in place. We also provide an introduction to sampling, where good analysis can be achieved using comparatively small amounts of representative data.
After you have your data, you need to decide how best to present and interpret it. We cover the importance of control charts to help you identify process variation so that you know when to take action and when not to.
We also look at developing an appropriately balanced set of measures to help you understand what influences and affects your results, and in doing so we reference a number of traditionally lean measures, including Takt Time.
