The correct choice is rooted in the need to align the business case with the overall strategy and vision of the organization, particularly in relation to market share. Business architecture provides a comprehensive view, incorporating elements like business goals, objectives, processes, and organizational structure that are crucial for understanding how changes can influence market share. It facilitates alignment between business objectives and operational capabilities, illustrating how initiatives aimed at increasing market share integrate with existing business functions.

A feasibility study, while valuable in determining whether a project or initiative can successfully be executed, does not specifically define how to increase market share. Scheduling and cost control focus on the management of project timelines and budgets rather than strategically increasing market share. Scope decomposition, which breaks down project elements to clarify deliverables and objectives, may be beneficial in project management but does not directly provide the strategic framework necessary to illustrate approaches for enhancing market share.

Thus, business architecture stands out as the essential documentation and activity necessary for creating a business case that outlines the strategy for increasing market share.
