Establish the trade-study environment
3. 
How should the proposed solution affect the performance characteristics of the 
integrated software solution?
4. 
What is an acceptable level of difficulty associated with implementing and test-
ing the solution?
5. 
How should the solution impact software operational and sustainment processes?
These questions and others should be used to establish the trade-study entrance 
criteria for candidate solutions. Entrance criteria provide the prerequisite conditions 
that must be satisfied for a candidate solution to be included in the list of viable can-
didates. Viable candidates may be prioritized to establish an authoritative ranking 
among the alternatives prior to the conduct of the trade-off analysis. The list of prior-
itized alternatives should be presented to stakeholder representatives at the trade-study 
kick-off meeting. Stakeholders should be canvassed to identify any further factors that 
may contribute to a candidate solution from being considered or ranked differently.
