Top Five List for Systems Engineering

1. Top Five ListforSystems Engineering Presented by:Francis Peter Management Sciences, Inc. Francis Peter

2. INTRO: • What are the Top 5 most important elements in Systems Engineering and Analysis? • Some Ideas: • Requirements • Interfaces • Functions • What are your top elements? • Architecture • Configuration Management Francis Peter

3. #5 Requirements • Sources: Customer, your domain knowledge, analyses, etc. • Decomposition: tiered specifications, allocation, traceability, etc. • Requirements Domain: • Known Knowns • Known Unknowns • Unknown Knowns • Unknown Unknowns Francis Peter

4. #4 Stakeholders • Who has a stake in how the system is designed and built? • Customer (contracting and/or technical agency) • End User Community • Your company, management, and design team • Test and Evaluation community • AFOTEC, OPTEVFOR, Army? Francis Peter

5. #3 Baselines • Provide a specific project view at various points in the development process • Functional • Allocated • Should be integrated with the Configuration Management process • Should be traceable between baselines • Product • Physical Francis Peter

6. #2 Know Thy Boundaries • Things break at interface points • Physically and functionally • Detailed control of functional boundaries guarantee nothing left out, nothing “doubled” • Detailed control of interfaces mean functions communication and work on both sides • Use FMEA to optimize boundary choices • Break each interface with no data/bad data • Determine effects on system and mitigation required Francis Peter

7. #1CONTEXT • Every system is part of a larger system • How does your system fit into this larger system? • What interfaces exist between your system and the larger system? How are they defined? • Is your system completely defined within this context? • What environmental constraints are imposed on your system? Francis Peter

8. 5 Pillars of System Engineering • Requirements • Functions • Components • Interfaces • Context Or the Five Legged Stool Francis Peter
