Explanation

Using standards in specification is very convenient. They reduce the time and effort to produce. They tend to be very accurate with correct technical terminologies. They are well recognised and accepted by a wide range of suppliers and buyers. However, since a standard is very specific, complex and lengthy, it requires a lot of time to be drafted and approved. Therefore, standard tends to be static and don't encourage innovation. It may also not accommodate latest technology and trends.

Explanation

3D-printed parts can replace traditional metal parts. They are also more easily customised to fit customer's needs. This technology is an example of threat of substitute in Porter's Five Forces model.

Substitute goods or services that can be used in place of a company's products or services pose a threat. Companies that produce goods or services for which there are no close substitutes will have more power to increase prices and lock in favorable terms. When close substitutes are available, customers will have the option to forgo buying a company's product, and a company's power can be weakened.

Explanation

There are three basic groups of WLC (whole life-cycle costing) models:

- Decision support models

- Simulation models: Life cycle cost is an essential approach to decide on alternative rehabilitation strategies for infrastructure systems. Monte Carlo simulation approach is used to develop a stochastic life cycle cost (SLCC) model and methodology in order to compare different rehabilitation scenarios/alternatives for infrastructures, such as water mains. This method assumes that some inputs are randomly variable in a range of values.

- Optimisation models

Explanation

The scenario is very long with many distracting data. Students need to read carefully and use their experience to solve this problem.

The company is developing a new component which requires different type of material. But this component will not be available for mass production in 1.5 years. This means the company still needs to produce the current components with current materials until the development is finished. They must continue purchase the materials from current supplier through call-off orders. This situation is an example of straight re-buy.

Explanation

Over-specification can cause problems to buying organisation, include the following:

- Higher expense due to unnecessary features embedded into the product

- Stifle competition because higher requirements will lead to fewer suppliers in the market are able to supply

- Harder to evaluate the trade-offs between different features and attributes in the specification

Comprehensive and Detailed Explanation (paraphrased from CIPS L4M2 content)

CIPS L4M2 explains that direct costs are those that can be directly traced to a specific product, job, or project.

For a decorating contractor:

Paint (A) is clearly a direct cost – it is consumed on specific jobs, and the quantity and cost can be directly allocated to each project.

Items such as:

Ladder (B) – a piece of equipment used across many jobs. Its cost is typically spread over multiple projects; this makes it an indirect (overhead) cost.

Van (C) – used for transport across many contracts, again an indirect or overhead cost.

Electricity (D) – usually treated as an indirect or overhead cost, not allocated to a single job unless specially metered.

Understanding the difference between direct and indirect costs is important for whole-life costing and building a business case, because misclassifying them can distort unit costs and profitability.

Relevant CIPS L4M2 areas:

Cost classification: direct vs indirect, fixed vs variable

Costing and pricing in business cases

Whole-life cost and cost build-up analysis

Comprehensive and Detailed Explanation (from CIPS L4M2 – Sustainable Procurement Evaluation)

Environmental criteria: carbon emissions, waste, resource efficiency.

Social criteria: labour standards, equality, community impact.

Thus, 1 and 2 fit perfectly.

Items 3 and 4 are quality or service considerations, not sustainability metrics.
