What are function points?
Project management involves the process of planning, organizing motivating as well as controlling available resources to meet expected goals. A function unit, on the other hand, is a single unit of measurement that is used to express business amounts such as information systems to the user. The function point measures the actual size of the software as well as estimating the cost in dollars of a single unit based on past experiences. It is processed where systems are broken into smaller points and analyzed to estimate their performance. The process of project management involves execution of skills, techniques as well as expertise knowledge towards meeting a common goal by business firms.
However, the process of dividing units into discrete parts that can be easily analyzed, estimated and evaluated refers to functional points. Project managers assign resources to various business units and evaluate their performance during its progress. To measure a single unit of business sector, the functional point is an important tool of measurement. Functional points are managed through information systems such as database, external inputs, external outputs, external inquiries, logical files as well as interface files to establish an exact estimate of the single business unit.
Project management’s functional units have several elements including external inputs. It is a process that allows data and information to cross from external to internal parts of the system. External outputs are a common process that will allow the flow of data and information from inside to external parts. Since functional unit relies on experience to predict its future outcome, external inquiry element allows the system to retrieve information from logical files. It enhances retrieving of past information to help predict the future outcomes of the firm. The major work of project managers is to set standards that not only enhance profitability from the project but also minimizes the cost to be incurred.
The external interface is an important element of functional point containing related data that are used by project managers for reference purposes. It provides useful information that regards the operation of the project. It marks an important point where important reference are done. Internal logical files is another great element that contains an identifiable group of related data residing upon the applications and regulated through external units. Functional points allow project managers to use software methodology to estimate current performance with future performance as well as making informed decisions regarding utilization of resources effectively.
