Determines what Is
Determines what Can Be
Determines what Should Be
What is wrong with the current situation?
Is the need clearly articulated?
Who are the intended users?
How will they use our products?
How is this different from the present?
What specific capability will we provide?
To what level of detail?
Are element interfaces well defined?
What is the overall plan of attack?
What elements make up the overall approach?
Are these complete, logical, and consistent?
Which elements address which requirements?
Is the allocation appropriate?
Are there any unnecessary requirements?
Are the details correct?
Do they meet the requirements?
Are the interfaces satisfied?
Will the solution be satisfactory in terms of cost and schedule?
Can we reuse existing pieces?
What is our evidence of success?
Will the customer be happy?
Will the users’ needs be met?

Business Viability and Success
Subsystems often suboptimal to achieve best balance at system level
Ultimate system purpose must prevail against conflicting considerations
Long-term considerations (e.g., disposal) may drive technical decisions
Often must act as “honest broker”
Carries burden of educating customer on hard choices
Must think ahead to the next customer and next application
Must “challenge” all requirementsEthical Considerations

Briefing to the DisciplineTexas Board of Professional Engineers
September 10, 1999
SE is a way of thinking Discipline
Practiced by senior engineers with OJT
Is unique to the product/industry of the engineering firm
Should be taught within other engineering disciplines
Scientific foundations and body of knowledge have commonality across product/industry but are not unique to SE
SE team has engineers of all disciplines
SE is a discipline of engineering
Has scientific foundations that cross many other engineering disciplines
Has body of knowledge separate from other disciplines
Can be taught separately from other disciplines in an engineering school
Separate roles exist on the SE team for a specific productTwo Perspectives on SE
Scientific Foundations Discipline
Feedback and control
Prototypes for requirements
Prototypes for interface resolution
Body of Knowledge
Concept of operations
System life cycle phases
