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.

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.
