Explanation

Payback period is the time in which the initial outlay of an investment is expected to be recovered through the cash inflows generated by the investment. It is one of the simplest investment apprais-al techniques.

Since cash flow estimates are quite accurate for periods in the near future and relatively inaccurate for periods in distant future due to economic and operational uncertainties, payback period is an indicator of risk inherent in a project because it takes initial inflows into account and ignores the cash flows after the point at which the initial investment is recovered.

The formula to calculate the payback period of an investment depends on whether the periodic cash inflows from the project are even or uneven.

If the cash inflows are even (such as for investments in annuities), the formula to calculate payback period is:

Payback Period = Initial Investment / Net Cash Flow per Period

When cash inflows are uneven, we need to calculate the cumulative net cash flow for each period and then use the following formula:

Payback Period =A + (B/C)

Where,

A is the last period number with a negative cumulative cash flow;

B is the absolute value (i.e. value without negative sign) of cumulative net cash flow at the end of the period A; and

C is the total cash inflow during the period following period A

Cumulative net cash flow is the sum of inflows to date, minus the initial outflow.

From the scenario, you can see that the project team is developing a new product. They start with analysing the functions, and the costs of delivering those functions. This is a typical process of value engineering. You may read more on value engineering from the reference paper.

Comprehensive and Detailed Explanation (paraphrased from CIPS L4M2 content)

Standardising from many similar products to one common product is a classic variety reduction / standardisation decision.

In CIPS L4M2, when standardisation is discussed, the benefits highlighted include:

Economies of scale – buying larger quantities of a single product allows for better prices and volume discounts.

Reduced administration and handling costs – only one product code to manage, fewer invoices and orders, simpler stock control.

Simplified quality control – one specification and one performance profile to monitor.

Because the product is available from many suppliers, competition remains strong. This supports lower prices, not higher.

Option A (Lower costs) – correct, due to economies of scale and reduced process/handling complexity.

Option B (Fewer staff) – staff numbers are driven by overall workload, not just the number of product variants; standardising doesn’t automatically cut headcount.

Option C (Increased stock levels) – if anything, standardisation often reduces safety stock (you can pool demand into one line).

Option D (Increased costs) – contradicts the expected benefits of standardisation and competition between many suppliers.
