Sean is using FUNCTION POINT (d) method for forecasting the time and cost of developing a customized software program by looking at the number of inputs, outputs, inquiries, files, and interfaces.
Explanation:
The function point is a "unit of measurement" to express the amount of business functionality an information system (as a product) provides to a user.
The outcome of a function point count provides the metric 'unit of software delivered' and can be used to assist in the management and control of software development, customisation or major enhancements from early project planning phases, through to the ongoing support of the application.
