Unit 2.2 Flashcards
requirements engineering
assures the customer that all requirements can be accounted for in the design at any stage and that no unnecessary requirements are included
traceability
is a feature of a top-down design, which guarantees that requirements can be satisfied at any stage
requirements traceability
what is the systems engineering framework
- systems engineering process
- systems engineering management
- systems engineering tools
- related disciplines
concentrate on the intent and main aim of each application of
this foundation process
systems engineering process
emphasize on the early acquisition phase activities (as this is where systems engineering has the most impact)
systems engineering process
Oversees the systems engineering process and plays a monitoring, directing, controlling, and reporting role
systems engineering management
is critical and is centrally placed in the framework
management [systems engineering management]
to help managers and process people undertake their tasks. these range from techniques and processes through information system to standards.
systems engineering tools
include requirement management systems, and assorted analysis, synthesis and evaluation tools.
Process tools
include popular engineering standards and capability maturity models.
Management tools
Technical and non-technical disciplines are related to systems engineering
related disciplines
Systems Engineering relies on the continual application of the simple
problem-solving process of ______
Synthesis
Evaluation
Analysis
Commences with the perceived need for the system and the development of formal requirements where a number of tools & techniques can be employed
analysis
Analysis Continues throughout what phase?
acquisition phase
Early on, focused at the system level (logical design) but later it is used to assist with the determination of requirement for subsystems, assemblies, and components (physical design).
analysis
is performed throughout its life-cycle to:
✔ Investigate trade-offs between requirements and design
✔ Consider the alternatives
✔ Evaluate the decision
evaluation
The “design” and “creation” function which proposes how we achieve what the analysis has told us
synthesis
Limited in early stages to decisions relating to overall technical approach and broad physical architectures. But later, synthesis becomes very detailed.
synthesis
what is the output of evaluation?
selection or confirmation of design
System engineering life cycle
pre-acquisition phase
acquisition phase
utilization phase
retirement phase
Evaluation may result in a set of ____ that need to be addressed.
discrepancies
