Define
Objectives and Requirements
Analysis,
objectives and requirements must be expressed in precise, explicit
terms to serve as the basis for sound decisions. They should
define the need, the user, and the availability of resources
bounding the scope
Alternatives
for consideration will be either predetermined or developed
specifically for the analysis. Candidate alternatives may be the
product of systems engineering synthesis activities and represent
existing (standard), modified, or original designs. Candidate
alternatives should reflect the widest possible range of
distinctly different solutions if the overall goal of optimized
system design is to be achieved.
Next, candidate alternatives identified through unconstrained
synthesis or brainstorming may be screened based on their ability
to solve the problem. This ensures that the analysis effort does
not waste time on nonproductive solutions.
A second screening may be performed on the basis of
attainability/affordability: Are the candidate alternative
solutions achievable within time and budgetary constraints?
Remaining candidate alternatives become the decision alternatives.
These alternatives are described fully and carefully. Sufficient
detail must be available to judge the relative worth of each
workable, attainable alternative. If an insufficient number of
candidate alternatives survives the screening process, the study
constraints should be reexamined and all candidate alternatives
re-screened, or the synthesis and possibly functional analysis
activity must be reinitiated.
