CBA has two purposes:
1. To determine if it is a sound investment/decision (justification/feasibility),
2. To provide a basis for comparing projects. It involves comparing the total expected cost of each option against the total expected benefits, to see whether the benefits outweigh the costs, and by how much.
CBA heavily depends on individual estimates and benefits estimates, we at olive tree ensure accuracy of these two elements while assisting in other related work.
