- Problem Definition
After MARR identified in previous blog, now Economist need to analyze the Project whether it will be investable or not based on calculated 15.13% MARR as a discount rate. Currently there are another 2 proposals of with similar scope prepared by another Project Team for other Client. However due to resources availability they need to select only 1 Project to be proceed.
- Identify the Feasible Alternative
With MARR had been identified, to investigate which Project will be proceed, Economist Team could analyze utilizing Equivalent Worth method such as Present worth (PW), Annual worth (AW) and Future worth (FW) of below alternative.
Figure 1: Alternatives cash flow figure
- Development of the outcome for Alternative
a. Present Worth
In general words, it is a future amount of money at specific point in time. Calculating the present value assumes that we knows both the future amount and the applicable discount rate. Utilizing these information we could identified the present value.
b. Future Worth
The future value is used to calculate what the value at a future date would be for a series of periodic payments
c. Annual Worth
Annual worth (AW) Analysis is equivalent uniform annual worth of all estimated receipts (income) and disbursements (costs) during the life cycle of a project
Below is the calculation table
Table 1: Equivalent worth calculation
4. Selection of Criteria
a. Present of Worth
This method is based on the concept of equivalent worth of all cash flows relative to some base or beginning point in time called the present. All cash inflows and outflows are discounted to the present point in time at an interest rate that is generally the MARR.
A positive PW for an investment project is a dollar amount of profit over the minimum amount required by investors. It is assumed that cash generated by the alternative is available for other uses that earn interest at a rate equal to MARR.
b. Future Worth
The FW is based on the equivalent worth of all cash inflows and outflows at the end of the planning horizon at an interest rate that is generally the MARR.
c. Annual Worth
AW of a project is an equal annual series of dollar amounts, for a stated study period, that is equivalent to the cash inflows and outflows at an interest rate that is generally the MARR
5. Analysis and Comparison of the Alternatives
From the result, then Project A is fail since PW, FW and AW amount is less than 0. While Project B and C both meet the selection criteria.
6. Selection of the Preferred Alternative
Table 1 result can be summarize as follow:
- PW : Project C > Project B > Project A
- FW : Project C > Project B > Project A
- AW : Project C > Project B > Project A
From above result, Project C is selected since it slightly higher than Project B.
- Performance Monitoring and the Post Evaluation of Result
Since the result is so tight, then Project Team should ensure the Proposal could meet estimation basis. To optimize the profit, proper control and monitoring should also be done to mitigate the risk.
