A consensus Business Activity Model (BAM) is a diagram that shows the high level activities that an organisation performs or delivers and the flow or sequence of the activities. It helps to understand what an organisation does, how it does it, who does it, where it does it and why it does it from a common or shared perspective of all relevant stakeholder groups. Therefore, options A, C and D are true statements about a consensus BAM. Option A is a true statement, as a consensus BAM is a conceptual model that represents a business situation or problem at a high level of abstraction. It helps to simplify and clarify the complexity and ambiguity of the business situation or problem. Option C is a true statement, as a consensus BAM shows the logical sequence of process steps that the organisation follows or performs to achieve its objectives and outcomes. It helps to identify the order and dependencies of the activities and how they are connected or related. Option D is a true statement, as a consensus BAM forms the basis of subsequent gap analysis that compares the current and desired situations or problems and identifies the differences or gaps between them. It helps to determine what changes or improvements are needed to bridge the gaps and achieve the desired situation or problem. Option B is not a true statement, as a consensus BAM does not show who undertakes the business activities, but what the business activities are. The actors or performers of the business activities are shown in another technique, such as RACI chart. Option E is not a true statement, as a consensus BAM does not describe a stakeholder’s perspective on what the business does, but a common or shared perspective of all stakeholder groups on what the business does. A stakeholder’s perspective on what the business does is described in another technique, such as CATWOE.
