Software engineering and development
The software development project must be organized around the IPPD philoso-
phy and tenants. To accomplish this, the scope of the software development effort 
must recognize and address the dependency of the software product on the comput-
ing environment, and the lack of a “manufacturing” phase of the software life cycle. 
Software products involve a form of distribution where the electronic distributable 
files are either replicated, packaged, and shipped to distributors or retailers, or the 
files are provided via web services for download. Therefore, the software IPPD 
organizational framework for work to be performed must reflect the structure iden-
tified in 
Figure 5.4
. The boxes that are shaded represent separate project elements 
that should be managed utilizing an IPT. Each of these IPTs should be responsible 
for the definition, implementation, and qualification of the software product or pro-
cess they govern.
