Composing a compelling business case requires the proposer to write in the language of the approvers.
Generally, approvers are business executives or important shareholders whose major interest is the profitability of the firm. Business case proposer may embed the following contents:
- Return on investment: according to Investopedia, Return on Investment (ROI) is a performance measure used to evaluate the efficiency of an investment or compare the efficiency of a number of different investments. ROI tries to directly measure the amount of return on a particular investment, relative to the investment's cost. A business case would seem more attractive if the proposal is expected to have high ROI.
- Time to market: Time-to-market (TTM) refers to the time from which a company initially con-ceives a product or service idea to the point when the actual product or service is accessible to buyers in the market (Afonso et al., 2008). The speed at which companies can introduce products into the market is critical for sustaining competitive advantage, and the reduction of product development cycle time has become a strategic objective for many technology-driven firms.
- Customer satisfaction: Keeping existing customer to stay in the business can affect greatly on the profit margin of a firm. A new proposal that finds the way to innovate while keeping the current customers satisfied may gain the interest of senior management.
- Improving productivity: Productivity is the measure of how efficient and effective a firm is. Im-proving the productivity means that with the same or lesser input, better output is generated. In-creasing productivity also improves the profitability of a company.
- Risk management: Any business activity contains inherent risks. For example, for a mining company to be truly responsible, it must keep all of its workers safe, healthy and motivated, meet the expectations of the local community and government for the region in which it is operating, ensure it impacts on the environment positively if at all, as well as achieve the financial objectives set by its investors for both the short and long term. Managing risks well improves the production throughput and maintains customer satisfaction.
In the scenario, Robert is trying to convince the senior management to adopt e-procurement system by insisting on potential productivity improvement. This is the right approach. A business plan should engage and please senior management and directors. An appealing business case tells them how important things to the business (such as productivity, return on investment, customer satisfaction or costs) are affected by the plan.

Detailed Explanation:Acceptance testing verifies that the supplied product meets the buyer's specification before it is formally accepted. This type of testing typically occurs during delivery or installation phases.
Reference: CIPS Level 4, Quality Assurance in Procurement.

Specifications for through-life contracts must be clear. They should use precise technical language and avoid any ambiguity as much as possible. In most cases, 'good quality' is ambiguous. The con-tractor doesn't know exactly which product the buying organisation needs and how to supply that product.
Other notices for description of requirement are:
- Short and simply description
- Clear definitions at the beginning of the documents
- Clarify abbreviations (if any), but abbreviations should be avoided as much as possible
- Avoid any 'slang'
- Use imperative forms of language whenever possible.

In this scenario, the final product has vast range of parts. The second problem is lacking any part can cause disruption to the production process. So GE has 2 things to do: to reduce the part varie-ties, and secure the supply. Part standardisation is the best option here. It can simplify the range of parts or materials used, and simultaneously, it expands the supply base of GE. If a supplier fails to deliver the part, the company always has other options to replace.
Costs are also a concern, but bottleneck in production imposes a serious risk to the organisation. Driving down costs using market competition cannot be a foremost priority.
Increasing production may help to reduce bottleneck. However, it will also increase the inventory of finished products and unnecessary upkeep costs.
