• Assessing prediction systems 

    Kitchenham, Barbara; MacDonell, Stephen; Pickard, Lesley; Shepperd, Martin
    For some years software engineers have been attempting to develop useful prediction systems to estimate such attributes as the effort to develop a piece of software and the likely number of defects. Typically, prediction ...
  • Factors systematically associated with errors in subjective estimates of software development effort: The stability of expert judgment 

    Gray, Andrew; MacDonell, Stephen; Shepperd, Martin
    Software metric-based estimation of project development effort is most often performed by expert judgment rather than by using an empirically derived model (although such may be used by the expert to assist their decision). ...
  • Measurement of database systems: an empirical study 

    MacDonell, Stephen; Shepperd, Martin; Sallis, Philip
    There is comparatively little work, other than function points, that tackles the problem of building prediction systems for software that is dominated by data considerations, in particular systems developed using 4GLs. We ...
