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
