Level of Detail
Systems Engineering Handbook ???
focus on engineering practices
???
based on unique customer requirements and best practices
from the organization
Very little tailoring allowed ??” requires contract change Based on waterfall life-cycle phases plus unique phases for internal research and development
Formal reviews (
with customer) ??”
systems requirements review,preliminary design review, criticaldesign review
Data management for all formalwork products ??”
plans, drawings,specifications, and prototypes
Verification and validation by 3rd party or with external witnesses
High-level process descriptions
Tailoring expressly forbidden
Based on roles in acquisition process
Process execution review by managers, technical details reviewed by engineering, all activities audited by customer
Contracts library with limited access containing specifications, requests for proposals, proposal responses, contract and contract status, vendor performance and preferred vendor lists
All activities audited by customer or 3rd party representative
Very detailed guidelines with checklists
Buyer Guidelines ???
focus on open market acquisitions
??? based on government regulations, unique customer requirements, and corporate guidelines
Some tailoring done on most projects Based on CMM for Software Key Process Areas
Level of detail varies by processarea??? detailed management processes??? high-level engineering processes
Internal peer reviews (
some involve systems engineering and acquisition participants)
Configuration management procedures around change control boards and software library
Both product and process review, emphasis on process assurance
Standard Software Process ???
focus on project management practices ???
based on best practices and Project Management Institute
