Even though a significant number of estimation models have been proposed for development projects, few have been proposed for software maintenance. This paper reports on two field studies carried out on the use of functional size measures in building estimation models for sets of maintenance projects implementing small functional enhancements in existing software. The first field-study reports on models built with 15 projects making functional enhancements to an internet-based software program for linguistic applications. The second field study analyses 19 maintenance projects on a single real-time embedded software program in the defense industry. Both field studies collected functional size measures using version 2.0 of the COSMIC-FFP functional size measurement method. Also both field studies classified projects into two classes of project difficulty in order to aid identifying subsets of projects with greater homogeneity in the relationship of project effort to functional size. This paper is the first published paper reporting on the use this second generation of functional size-measurement methods in a maintenance-estimation context.
