Explanation
CATWOE is a technique for exploring stakeholder business perspectives by identifying six elements:
Customer, Actor, Transformation, Worldview, Owner and Environment. It helps to understand how different stakeholders perceive a business situation or problem and what they expect from a solution. Therefore, option D is the correct answer, as Paul and his business partner are in disagreement on their worldview element of CATWOE. Worldview is the element that describes the beliefs, values, assumptions or principles that underpin a stakeholder's perspective. It helps to explain why a stakeholder thinks that a business situation or problem is worth addressing or solving. Paul and his business partner have different worldviews regarding the possibility of extracting natural gas from their land. Paul believes that it is a safe, profitable and reasonable option that will improve their financial situation. His business partner believes that it is a dangerous, unattractive and unacceptable option that will compromise their vision of living off the land. Option A is not a correct answer, as Paul and his business partner are not in disagreement on their customer element of CATWOE. Customer is the element that describes who benefits from or is affected by a business situation or problem or its solution. It helps to identify who are the main beneficiaries or victims of a business situation or problem or its solution. Paul and his business partner have the same customer, which is themselves as the owners of the farm. Option B is not a correct answer, as Paul and his business partner are not in disagreement on their actor element of CATWOE. Actor is the element that describes who carries out or performs a business situation or problem or its solution. It helps to identify who are responsible for implementing or delivering a business situation or problem or its solution. Paul and his business partner have the same actor, which is themselves as the owners of the farm. Option C is not a correct answer, as Paul and his business partner are not in disagreement on their transformation element of CATWOE. Transformation is the element that describes what changes or processes take place in a business situation or problem or its solution. It helps to identify what inputs are converted into outputs in a business situation or problem or its solution. Paul and his business partner have the same transformation, which is extracting natural gas from their land.

The business analysis guidance makes it clear that a business case is not a "one-and-done" document that stops being useful at implementation. Instead, it is revisited at multiple decision gates through the lifecycle, including points after development estimates are known, before deployment, and later during operation when benefits realisation is checked. This directly contradicts statement A, because the business case remains relevant beyond implementation to confirm assumptions and verify whether expected benefits were actually achieved.
Statement B is also incorrect. The guidance explicitly states that the "do nothing / maintain the status quo" option should always be considered and will usually appear in the business case. It may sometimes be rejected due to unacceptable consequences, but it should still be included so decision-makers understand the risks of inaction.
Statement C is correct because the business case should consider both tangible and intangible benefits. The documentation explains that many benefits (for example improved customer satisfaction or staff morale) can be intangible, meaning they cannot be credibly valued in advance. While organisations vary in how they treat intangibles, the framework recognises them as legitimate benefits (with the caution not to overstate them or assign "spurious" values).

A power/interest grid is a tool for analysing stakeholders based on their level of power or influence and their level of interest or involvement in the organisation or project. The grid has four quadrants: high power, high interest; high power, low interest; low power, high interest; and low power, low interest. The position of a stakeholder on the grid can help to determine the appropriate strategy for engaging and communicating with them. Therefore, option A is the correct answer, as the head of IT services currently occupies the high power, low interest quadrant. This means that he has the authority or ability to affect the outcome of the project, but he does not show much concern or involvement in it. Option B is not correct, as some power and influence and some interest would place the head of IT services in the middle of the grid, which is not a distinct quadrant. Option C is not correct, as high power or influence and high interest would place the head of IT services in the top right quadrant, which is not consistent with his lack of involvement. Option D is not correct, as low power and influence but high interest would place the head of IT services in the bottom right quadrant, which is not consistent with his authority.

A business case is a formal written proposal that details the costs and benefits of a proposed business change or solution. It helps to justify and secure the approval and funding for a proposed business change or solution. Costs and benefits can be classified into two types: tangible and intangible. Therefore, option D is the correct answer, as it identifies which categories of costs and benefits are described in this extract respectively. Intangible costs are costs that have no physical existence and cannot be measured or quantified easily by human senses. Examples of intangible costs are reputation, image, morale etc. An example of intangible costs in this extract is significant investment in terms of software licenses and annual maintenance fees, which will not be negotiable until year four of the proposal, as it has no physical existence and cannot be measured or quantified easily by human senses. Tangible benefits are benefits that have physical existence and can be measured or quantified easily by human senses. Examples of tangible benefits are revenue, profit, market share etc. An example of tangible benefits in this extract is improved management information, in addition to the boost it will give to our image with our established customers, as it has physical existence and can be measured or quantified easily by human senses. Option A is not a correct answer, as it does not identify which categories of costs and benefits are described in this extract respectively. Tangible costs are costs that have physical existence and can be measured or quantified easily by human senses. Examples of tangible costs are equipment, materials, labour etc. There is no example of tangible costs in this extract. Intangible benefits are benefits that have no physical existence and cannot be measured or quantified easily by human senses. Examples of intangible benefits are satisfaction, loyalty, quality etc. There is no example of intangible benefits in this extract (although image could be considered as an intangible benefit). Option B is not a correct answer, as it does not identify which categories of costs and benefits are described in this extract respectively. Tangible benefits are benefits that have physical existence and can be measured or quantified easily by human senses. Examples of tangible benefits are revenue, profit, market share etc. An example of tangible benefits in this extract is improved management information, in addition to the boost it will give to our image with our established customers, as it has physical existence and can be measured or quantified easily by human senses. Intangible costs are costs that have no physical existence and cannot be measured or quantified easily by human senses. Examples of intangible costs are reputation, image, morale etc. An example of intangible costs in this extract is significant investment in terms of software licenses and annual maintenance fees, which will not be negotiable until year four of the proposal, as it has no physical existence and cannot be measured or quantified easily by human senses. Option C is not a correct answer, as it does not identify any category of cost or benefit that has been described in this extract.
