Function Points are a unit of measure like hour is to measuring time or inch is to measuring distance. A unit plays an important role in understanding and communicating metrics like average cost. In software application, we generally consider a screen or a report as a function point, But these are not. Instead Function Point is an elementary business process. From a project manager point of view measurement is necessary to manage a project. It also helps project managers to make project decisions.
What is Function Points Analysis or FPA?
Except the software industry all other industries are managed by unit cost. If you like to define Function Point Analysis, than You can say It is a
- Structured technique of classifying components of a system.
- Method to break systems into smaller components, so they can be better understood and analyzed.
- Measures software by quantifying its functionality provided to the user based primarily on the logical design.
- Logical functionality from a sophisticated user view rather than a physical view.
- Standard method for measuring software development from the customers point of view.
Advantages of Function Point Analysis
- Improves requirements documentation.
- Improves the estimating process.
- Improves the communication of workload.
- Improves the understanding of business functions.
- Improves traceability of requirements through implementation.
- Improves the allocation of resources.
