How is project cost calculated?

To use parametric estimating, first divide a project into units of work. Then, you must determine the cost per unit, and then multiply the number of units by the cost per unit to estimate the total cost. … As an aspect of quality management, the cost of quality is usually an indirect project cost.

What is the importance of cost estimation?

Cost estimation process helps in identifying project risks and provides an option to discuss alternatives if new requirements are needed to be added. The accurate project costing plan enables one to weigh anticipated benefits against anticipated costs to assess if the project makes sense.
