Adapting function point analysis to Jackson system development

Overviews of the estimation model function point analysis (FPA) and the operational software development method Jackson system development (JSD) are given. The adaptation to JSD projects of two main versions of the FPA method is described. A number of issues are raised concerning both the applicability of FPA-based techniques to JSD projects and general ways in which FPA estimation might be improved. A summary is presented of the results obtained by applying the two adaptations to an actual commercial JSD project, and various objectives are highlighted for future research
