A. Explain the net present value and return on investment for a cost–benefit analysis. Why would these calculations be used?
B. What is an evolutionary WBS? How does it address the problems associated with a conventional WBS?
A. Net present value : It is the cumulative present worth of positive and negative investment cash flow using a specified rate to handle the time value of money.
Net present value for cost-benefit analysis uses a discount rate, determined from the company's cost of capital to establish the present value of a project . Discount rate is used to determined the present value of both cash outlays and receipts.
Return on investment - It is th ratio of net cash receipts of the project to the cash outlays of the project. Trade-off analysis can be made among projects competing for investment by comparing their representative return on investement ratios.
These calculations would be used for investment purposes.
B. Evolutionary Work Breakdown Structures (WBS) should organize the planning elements around the process framework rather than the product framework. It allows the analyst to address all the problems by allowing the development of an iterative work plan. Evolutionary WBSs are organised in a standard manner across all projects y workflow, phases and the specific tasks that are accomplished during an individual iteration. This decouples the structure of an evolutionary WBS from the structure of the design of the product and prevents committing to a specific architecture of a new system.
