Choosing and adapting the best-fit PMLC model is a subjective decision based on several variables. Figure 2-9 is a display of the decision process.
Part II discusses the details further. It is sufficient at this point to be aware of the fact that having chosen a specific project approach you are not yet prepared to begin the project. Specific internal and external factors will have to be taken into account and final adjustments to that approach made. These are discussed throughout Part II.
Although you may have easily arrived at a best-fit approach and best-fit PMLC model based on the confidence you have with the RBS and the degree of completeness of the WBS, there is more work to be done before you can proceed with the project. First you have to assess the impact, if any, of a number of other factors. These are discussed below. Second, you have to make the necessary adjustments to the chosen PMLC model to account for that impact. These are discussed in Chapters 10, 11, and 12. The factors that I'm talking about here are those that might affect, and even change, your choice of the best-fit PMLC model. For example, if the PMLC model requires meaningful client involvement, and you have never been able to get that, what would you do? You'll examine the options in the chapters of Part II. For now I want to take a look at those other factors and how they might impact the PMLC model.
