Product software implementation method result in ambiguity when questions arise in the execution of the implementation process. On the other hand methods can be used as a profession, meaning that the method should be taken strict and the usage of the method should be a profession, instead of a guiding principle. This view is very useful if the implementation process is very complex and is very dependent on exact and precise acting. Organizational and quality management will embrace this view, as a strict usage of any method results in more clarity on organizational level.

Analysis effort method Unit testing and Testing. The method does not include any times for training or project management. This method should be used as one of a number of estimation techniques to obtain a more accurate estimate. Analysis effort method The analysis effort method is a method for estimating the duration of software engineering projects. It is best suited to producing initial estimates for the length of a job based on a known time duration for preparing a specification. Inputs to the method are numeric factors which indicate Size (S), Familiarity (F) and Complexity (C). These, with a duration for preparing the
