Any model posted for predicting rework most likely would not apply to your specific situation. <br /><br />You need to keep in mind that High Maturity is all about uncertainties, probabilities, predictions, and confidence levels - which are evaluated in terms of value to your business. You have to determine the strategic business goals for your organization and then define the Quality and Process Performance Objectives that support and trace to these objectives. Once you do this exercise, it will help you define your critical processes and measures. Then you will be able to understand if rework prediction is important to your or business objectives. You will also have to define what rework is. What kind of rework is critical to your organization? Is it repeated requirements reviews? Repeated design reviews? Multiple revisions to a document? Retests? etc. <br /><br />You have to be specific about what your PPMs will model. Do a root cause analysis to determine the factors that you have control over that contribute to rework. Probably skill level, requirements volatility, complexity, etc. Once you have done this analysis you evaluate your historical data to determine what data measures you have collected over the year(s) that provide insight into these factors, and then you perform the necessary regression analysis to derive your PPMs.<br /><br />Hope this explanation helps.Henry Schneiderhttps://www.blogger.com/profile/12588884323537313318noreply@blogger.comtag:blogger.com,1999:blog-5843108629504158226.post-65863533760437166372011-07-27T02:57:27.482-07:002011-07-27T02:57:27.482-07:00very clearly elaborated.
