Application Guidelines of ANSI/EIA-632
(What not How Oriented)
• Decide Which of the 33 Processes Apply
• Decide Which Requirements Apply for the
Processes Selected
• Establish Appropriate Policies & Procedures
• Define Appropriate Tasks for Each of the
Selected Requirements

Application Guidelines of ANSI/EIA-632
(What not How Oriented) Continued
• Establish Methods and Tools to Support Task
Implementation
– Representative Tasks Along With Their Expected
Outcomes Are Provided in Annex C
• Appropriate Processes Are Applied Recursively
and Iteratively
• Many Associate Tasks Are Concurrent And
Highly Iterative And Have Interactive
Dependencies That Lead To Alteration Of
Previously Established Technical Requirements

EA/SD System Engineering Impact on
Information Systems
• Need to Capture System Information Once in Common
Interoperable Format
• Apply Distributed Tools for Collaborative Assessment
& Optimization Including Pervasive Modeling &
Simulation Throughout the System Engineering
Product Life Cycle
• Utilize ANSI/EIA-632 Technical Management and
Technical Evaluation Processes Throughout the DoD
Acquisition Process
• A Broad, Extensible Representation Approach Is Key
– Use EIA-927 Common Data Schema For Complex Systems
