To make estimates and measurements of function points of the project at every stage of its life cycle is possible to determine whether the functional requirements increased or decreased, and whether this variation corresponds to new requirements or requirements that already exist and were just more detailed. A gap analysis template visualizes the difference between reality and target for your organization, making it easy to show employees where there is still room to grow. Function point metrics, measure functionality from the users point of view, that is, on the basis of what the user requests and receives in return, This gives a dimensionless number defined in function points which we have found to be an effective relative measure of function value delivered to our customer. Elementary process: The smallest unit of activity that is meaningful to the end user in the business, External Output (EO): An EO is an elementary process that generates data or control information sent outside the applications boundary, External Inquiry (EQ): An EQ is an elementary process made up of an input-output combination that results in data retrieval. Fortunately, in this situation, the problem was identified early in the process and the proposed COTS solution was rejected. The input datas are processed by the application to stored in a file with logical structure. The application requirements define addition of the following functions: The technology being employed by developers in order to meet the requirements makes no difference to the FPA sizing.
