Free Practice Questions for CIPS L4M2 Exam

Comprehensive and Detailed Explanation (from CIPS L4M2: Specification Design)

Performance specifications describe what the product or service must achieve, not how to achieve it.

CIPS recommends them when:

Innovation or supplier expertise is desired, and

Outcomes can be measured functionally.

For an intelligent IT system, suppliers can design innovative solutions if the focus is on performance outcomes rather than technical conformance.

Relevant CIPS L4M2 Sections:

Types of specifications (performance, conformance, output)

Encouraging innovation through supplier freedom

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

Public annual reports can be a source of information that helps the procurement professional to analyse an industry's cost and revenue using the line of best fit. Line of best fit is one of the most important outputs of regression analysis. Regression refers to a quantitative measure of the relationship between one or more independent variables and a resulting dependent variable. Regression is of use to professionals in a wide range of fields from science and public service to financial analysis.

In this case, by collecting and analysing 17 annual reports, the procurement manager can find the line of best fit which goes approximately through the middle of the data points with an equal num-ber of data points above and below it.

The slope of the line of best fit is the approximate variable costs the industry. The easiest way to calculate it is to take a point at the right-hand end of the line of best fit and note its cost and output levels. Divide the cost by the output and this gives and approximate figure for the cost per unit of output or variable cost. This gives an approximate value for the industry fixed and variable costs.

Explanation

The instrument plays a crucial role in steel manufacturing because it presents in the majority of products, in which case lacking this instrument would have significant impact on the organisation's output (production lines stop or damaging other machine). Otherwise, the risk of supply is high because there is limitation in supply. Therefore, it is considered as a strategic item in term of Kraljic's portfolio matrix. Procurement manager should form partnership with suppliers to maximise the value.

The following graph illustrates Kraljic's portfolio matrix:

Comprehensive and Detailed Explanation (from CIPS L4M2 – Market Analysis)

Supplier power is low when:

Buyers can easily substitute products (Option B).

Switching costs are low, so buyers can change suppliers without difficulty (Option D).

Low competition (A) or low innovation (E) strengthens supplier power, not weakens it. High quality (C) increases supplier leverage.

Explanation

Writing a specification and then procuring and using the product or service has a number of stages. The further on in the process you are, the less potential there is for cost reductions. Therefore, opportunities for cost reduction will be greatest in the two first stages: planning stage and pre-design stage.
