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.

RAQSCI stands for Regulatory, Availability, Quality, Service, Cost, Innovation.

LO 1, AC 1.1

Explanation

In this question, you have to calculate price variance and quantity variance.

Last month, 1 tonne of steel costed $216. This month, the price decreases to $181.1. Price variance = (P1 - P2)*Q2 = ($216-$181.1)*11 = $383.9

Quantity variance = (Q1-Q2)*P1 = -$216

Price variance is greater than quantity variance, therefore, price variance is the main cost driver.

Explanation

The buying organisation is keen to encourage innovation so they should use the outcome or output based specification. In an outcome-based specification, umbrella statements like 'good quality', 'ambient temperature', 'convenient way' are often used. This may confuse the suppliers, and it's hard to check the solution that supplier offers. On the other hand, ouput-based specifications often include measurable requirements. For example, a specification for air conditioning system states that the system should maintain the room temperature at 19-24 degrees Celsius. Therefore, output specification is more appropriate in this case.
