Overviewed in Chapter 2
Much more detail in Chapter 3.
Software Economics Parameters
Size: Usually measured in SLOC or number of Function Points required to realize the desired capabilities.
Function Points a better metric earlier in project
LOC (SLOC, KLOC ) a better metric later in project
These are not new metrics for measuring size, effort, personnel needs,
Process used to guide all activities.
Workers (roles), artifacts, activities
Support heading toward target and eliminate non-essential / less important activities
Process critical in determining software economics
Component-based development; application domain iterative approach, use-case driven
Movement toward lean everything!
Software Economics Parameters
Personnel capabilities of the personnel in general and in the application domain in particular
Motherhood: get the right people; good people; Can t always do this.
Much specialization nowadays. Some are terribly expensive.
Emphasize team and team responsibilities Ability to work in a team;
