Contemporary Approaches to MSS Effort Measurement

    Due to dominance of text-based (single media) systems in large environments and the relatively recent expansion of multimedia into mainstream systems development

  • Effort measurement based on System Size
    Boehm’s Constructive Cost Model (COCOMO) - lines of code
    Variation for Computer Aided Learning (CAL) -course delivery time and cost drivers
    Although some aspects are useful wider applicability to other types of multimedia development is unclear
  • Effort based on Functionality
    Function Point Analysis (FPA) - quantifies weighted contribution
    Gao and Lo suggest ineffective for multimedia - Why?
    -Large database maintained in transaction oriented system
    -component reuse infrequent in transaction systems development
    -extual output of business systems
