Table 19.2 is an example of a PPB containing the historical productivity results
from executing the process used for new development within an organization. There
are PPB elements for each of the five phases that this organization has in its life
cycle: Requirements Definition, Design, Implementation, Integration, and Systems
Test. Implementation for the example organization includes both the classic code
and unit test of a software system, plus implementation of individual nonsoftware
components. The first line under Requirements Definition is the number of hours to
define a complex requirement. There are elements for complex requirements, nominal
requirements, and simple requirements with values for the upper limit, mean,
and lower limit for each. The Design PPB elements are based on requirements and
follow the same structure.
