A consensus Business Activity Model (BAM) is a conceptual model that provides a high-level, strategic view of the business. It illustrates the essential activities required to achieve an agreed-upon business perspective, derived from merging the viewpoints of multiple key stakeholders. The model uses arrows to depict the logical dependencies and sequence between these activities, showing what must occur before another activity can begin. A primary purpose of creating this consolidated 'to-be' model is to use it as a baseline for gap analysis, comparing it against the current 'as-is' business processes to identify required changes and improvements.

B. A BAM intentionally omits who performs activities to focus purely on the necessary functions ('what'), not the actors ('who').

E. This describes an individual BAM created from a single viewpoint. A consensus BAM synthesizes multiple stakeholder perspectives into one agreed-upon model.

For A (Conceptual model): "A BAM is a conceptual model that shows the business activities that must be in place to support the business perspective." (p. 178, Section 7.4.2).

For C (Logical sequence): The arrows in a BAM diagram "show the logical dependencies between the activities." This establishes the logical sequence required for the business system to function. (p. 181, Figure 7.5).

For D (Basis for gap analysis): "The consensus model is then used to analyse the existing business situation... This is a form of gap analysis, where the required situation, as defined by the BAM, is compared with the existing situation..." (p. 183, Section 7.4.3).

For B (Incorrect): "The model does not show who carries out the activities or where they are conducted." (p. 178, Section 7.4.2).

For E (Incorrect): The text describes creating individual BAMs for each perspective and then creating "a consensus model that combines all of the individual models." This shows the consensus model is a merged view, not a single stakeholder's perspective. (p. 182, Section 7.4.3).
