Software Engineering

2.2.2 
Preliminary architecture definition stage
During this development stage the SWE-IPT establishes the functional architec-
ture for the software product by conducting functional analysis and allocation. 
Alternative functional designs should be evaluated and compared utilizing the soft-
ware analysis approach for performing risk assessments and trade-off analysis. The 
models, design documentation, and initial data dictionary should be prepared. The 
PDSS processes should be defined and their requirements documented in one or 
more process specifications.
