Software project duration

In many cases this can he done by applying more resources to the task - working overtime or procuring additional staff, for example. The critical path indicates where we must look to save time -if we are trying to bring forward the end date of the project, there is clearly no point in attempting to shorten non- critical activities. Referring to Figure 6. Calculate the end date for the project. Also those who measure obtain more knowledge about what enables them to be more productive and improve over time.

Are my comparisons accurate? These are some of the filters that you can use when checking an estimate. Keep in mind that if you filter too much you may end up with a sample size that is too small and not statistically valid. How accurate is my size measure? This report provides insight that can help make decisions on phased development if possible and how to minimize inaccuracies. See Report Subscriptions for more details. Do I have missing functionality in my size measure.

It is possible to uncover missing functionality midway through the project. This would then require change requests to include the functionality and an obvious discussion as to whether that functionality was inferred in the beginning. One way to check is to cross-check the categories of functionality against the industry standards.

This may show for example very low outputs against industry. This may be correct for that type of application but at least the difference is highlighted. The question is then asked — have all outputs have been identified? Practical Software Project Estimation, Chapter 6. My initial estimate is too high. Should I buy a package instead? This is often the first decision to make after the initial shock of the cost estimate.
