Preliminary architecture definition

Prepare for the PDR.
 The SWE-IPT should prepare for the PDR. The pur-
pose of the PDR is to present the consistent software requirements, functional 
architecture, and conceptual structural configuration to program management, 
customers, or other stakeholders. The architectural decisions that guided the 
formulation of the functional architecture should be identified. Architectural 
decisions must be traced to their impact on the WBS and program and tech-
nical plans. The software quality assurance inspection and audits conducted 
during the preliminary architecture definition should be reported. The risks 
identified during this stage of development and their risk abatement plans 
should be discussed.
