Answer:
The answer is: A feasibility report
Explanation:
A feasibility report's main purpose is to evaluate a proposed solution to determine how possible, reasonable and economically feasible is the application of the proposed solution.
When you evaluate the proposed solution several things must be considered including estimated costs of implementing the solution, under what constraints should the solution be considered and different alternative solutions.
After the pros and cons are evaluated, the feasibility report should either recommend to carry on or discharge the proposed solution based on legal, technical and economic conditions.
