Process for establishing Function Points

The deployment of the "Function Point" metric is associated with strategic objectives specific to each organization/company.

The suitability of the metric for these objectives should be assessed through a scoping and testing process prior to the deployment of the Function Point measurement process.

Example of an approach to implementing Function Point metrics and productivity.

Conclusion

IFPUG provides management with a unit of work that measures what is delivered by the IT department to the business units, allowing costs and deadlines to be reconciled.

Measures in Function Points or SNAP IFPUG Points are standardized, and therefore reproducible and enforceable, facilitating benchmarking, governance, and contractualization.

Numerous feedback reports demonstrate the gains achieved by the Point de Fonction measurement.

The approach is implemented on the basis of objectives defined by the IT department, applying a roadmap tailored to its objectives and the context of the Executive Management.
