Explanation
The event 'amend KPI' would affect the activity 'define performance targets', as the company would need to change its current performance target of gross profit margin to ROCE. The other activities would not be directly affected by this event, as they are either related to monitoring or defining other aspects of the business.
Therefore, option A is the correct answer.

A time based event is one that occurs at a regular or predetermined interval, such as monthly or quarterly. In this scenario, the printing of the monthly payslips is a time based event, as it happens every month. The notification from senior management is not an external or internal event, as it is not triggered by an external or internal stakeholder or situation. Therefore, option D is the correct answer.

A Business Activity Model (BAM) is a technique for modelling business activities within an organisation or project at a high level of abstraction. It helps to understand what an organisation does, how it does it, who does it, where it does it and why it does it. Therefore, options A and D are correct answers, as they apply to a BAM. Option A applies to a BAM, as multiple BAMs could be created to reflect different perspectives of different stakeholder groups within or outside the organisation or project. A BAM is not a single or definitive representation of the business activities, but a subjective and contextual view that depends on the purpose and scope of the analysis. Option D applies to a BAM, as the activities are most likely to be shown in boxes in a BAM. A BAM is typically represented as a diagram that consists of boxes and arrows. The boxes represent the high level activities that the organisation performs or delivers, and the arrows represent the flow or sequence of the activities. Option B does not apply to a BAM, as the owner should not always choose the final BAM. The owner is one of the stakeholder groups that may have a perspective on the business activities, but not the only or ultimate one. The final BAM should be agreed by all relevant stakeholder groups based on their needs and expectations. Option C does not apply to a BAM, as normally a consensus BAM will not be produced. A consensus BAM is a BAM that reflects a common or shared perspective of all stakeholder groups within or outside the organisation or project. A consensus BAM is not realistic or desirable, as different stakeholder groups may have different or conflicting views on the business activities. Option E does not apply to a BAM, as dependencies between the activities are shown in a BAM. Dependencies between the activities are the relationships or connections that indicate how one activity affects or influences another activity. Dependencies between the activities are shown by the arrows in a BAM diagram.

A high level Business Case is a document that provides a preliminary rationale and justification for a proposed business change or solution. It helps to establish the feasibility and desirability of the project and secure initial approval and funding for further investigation and development. Therefore, option A is the correct answer, as creating a high level Business Case would be the best activity to undertake at this point for introducing a new procurement system. A high level Business Case would help to define the problem or opportunity that motivates the project, identify and compare different procurement solutions based on their expected benefits, costs, risks and impacts, and recommend the preferred option for further analysis and evaluation. A high level Business Case would provide a solid foundation for proceeding with the project and preparing a detailed Business Case later on. Option B is not a correct answer, as creating a detailed Business Case would not be an appropriate activity to undertake at this point for introducing a new procurement system. A detailed Business Case is a document that provides a comprehensive rationale and justification for a proposed business change or solution. It helps to confirm the viability and worthiness of the project and secure final approval and funding for implementation and delivery. A detailed Business Case would require conducting extensive research and analysis on the preferred procurement solution and presenting its definitive benefits, costs, risks and impacts. A detailed Business Case would be premature and unnecessary at this point, as it would depend on the outcome of the high level Business Case first. Option C is not a correct answer, as it is too early to work on the Business Case would not be an appropriate activity to undertake at this point for introducing a new procurement system. Working on the Business Case is an essential activity for any project that involves significant business change or investment. It helps to provide evidence and support for the project and ensure its alignment with the organisation's strategy and objectives. Working on the Business Case would not be too early at this point, as it would help to establish the feasibility and desirability of the project and secure initial approval and funding for further investigation and development. Option D is not a correct answer, as confirming with the directors the costs and benefits would not be an appropriate activity to undertake at this point for introducing a new procurement system. Confirming with the directors the costs and benefits would require preparing a high level Business Case first to estimate and compare the financial implications of different options and recommend the best one for further development and implementation. Confirming with the directors the costs and benefits without preparing a high level Business Case first would risk providing inaccurate or incomplete information that may not reflect the value or feasibility of the project.
