§Alternative Solution
Space is a factorial combination of potential forms for each function
§Constraints include non-functional requirements of the proposed system, operational and organizational constraints of the client, and operational constraints
of the delivery team
–In some cases, common
sense will be applied to further
reduce the alternative space (i.e., unrealistic options - substantial data entry)
§An Effectiveness Rating, or relative evaluation is required to differentiate alternatives in terms of performance against functional requirements
§The Preferred Alternative will be identified through application of an additive value function of the normalized effectiveness ratings and HOQ weights
§Throughout the
evaluation process, the resulting alternative
instantiations will be evaluated against needs and wants to mitigate risks
Identify Preferred Alternative
Assign Effectiveness Rating
Alternative Solution Space (Assign. 5)
Value Mapping and Risk Mgmt
•Remove from consideration forms
that violate client or
group constraints
•Evaluate alternative system
instantiations against functional requirements
•Normalize effectiveness ratings
and apply HOQ weights
•Identify instantiation with highest satisfaction
value that does not violate constraints
•Continue to track risks and changes
to client needs as wants
•Combinatorial collection of forms satisfying functional
requirements
Apply Constraints to Solution Space
Alternative Evaluation Steps
The following process will be used to evaluate alternative options
leading to a preferred solution
