Preparing the software technical data package
The software TDP must be prepared to document each structural unit, component, 
and engineering assemblage that must be developed during software implementa-
tion. The software TDP consists of the technical documentation (diagrams, draw-
ings, specifications, data definitions, and software integration strategy) associated 
with structural units and components. The software TDP provides the formal rep-
resentation of the software physical architecture necessary for the software imple-
mentation stage of development. Software implementation involves the design, 
coding, and testing of structural units, and the assembly, integration, and testing 
of structural components. The effort associated with software implementation and 
testing will be made significantly more efficient and effective with a coherent, thor-
oughly specified and documented software physical architecture.
The software TDP is the technical description of the software product necessary 
for software implementation, acceptance testing, and post-development software sus-
tainment. Therefore, the TDP must be consistent with the evolving software product 
architecture, as well as compatible with all authorized change requests and propos-
als. The software TDP, together with software development folders, acceptance test 
results, and authorized change proposal, deviations, and waivers provide the basis for 
the software functional configuration and physical configuration audits (FCA/PCA).
