Yes, but not all of the software maintenances are likely to be measured with Function Point Analysis (FPA). Only the maintenances that CHANGE the software functional requirements can be measured by the Function Point Analysis (FPA), in this case IFPUG uses the term “improvement” instead of “maintenance”, exactly to MAKE the point that the improvement is not any kind of maintenance. In IFPUG’s CONCEPT, the improvement measures all the FUNCTIONS that will be added, changed or excluded from the application, as well as eventual functions of data conversion.

Maintenance for correction of defects or to keep only nonfunctional requirements are not measured by Function Point Analysis (FPA).
