Systems Engineering Process and WBS Flashcards
Why is Systems Engineering important?
Establishes 80% of lifecycle costs.
What does the SEP produce?
Creates a description of system parameters.
7 steps of SEP
Process inputs, requirements analysis, requirements verification, functional analysis, functional verification, synthesis, design verification
Name 6 process inputs.
customer needs, tech base, program decision requirements, performance based specifications, outputs from previous SEPs, constraints
Requirements Analysis purpose
develop functional and performance requirements
Requirements Validation purpose (4)
- requirements meets users expectations.
- Traces requirement to function.
- Ensures function addresses requirement.
- Resolves conflicts between requirement and functions.
Functional Analysis purpose (3)
- requirements into a functional architecture.
- Allocates functional requirements.
- Allocates performance requirements.
Functional Verification purpose (2)
- Verifies that the functional architecture
2. Traces physical/software elements to requirements.
Synthesis purpose (4)
- physical architecture.
- interfaces.
- system data.
- Physical descriptions
Design Verification purpose (5)
- Ensures requirements of the physical architecture are traceable to the verified functional architecture.
- Verifies that the design satisfies validated requirements baseline.
- Traces each function to corresponding physical software element.
- Ensures each physical or software element addresses at least one functional element.
- Resolves conflicts between functions and physical architecture.
Systems Analysis purpose
- Resolves conflicts.
- Decomposes and allocates requirements.
- conducts trade studies and assessments
- conducts effectiveness analysis
- manages risks
Control purpose
manage and document SEP
Name SEP outputs
- decision data
- system architecture
- performance specifications and baselines
WBS
work breakdown structure
tool to allow PMs and contractors to break large tasks into smaller, understandable sub-tasks.
WBS purposes (5)
- Road Map
- Design and track technical work
- Risk Assessment
- Manage engineering change proposals
- Structure budget and cost estimates.
