Functional Size vs. SE Effort ü 20 data points displayed (out of a dataset of 22) ü Included here is “raw” unadjusted data ü Most points are intra-company homogeneous ü Project size and hours are log transformed ü Common differences in counting requirements and operational scenarios Breaking point may tell us something about the diseconomies of scale in Systems Engineering

Size Driver Influence on Effort # of Interfaces and # of Algorithms drivers proved to be insignificant

Life Cycle Scope of the Model From ISO/IEC 15288 Most of the project data reported for COSYSMO covers the first 4 phases of the ISO lifecycle
