Comprehensive and Detailed 200 to 250 words of Explanation From Exact Extract of project-programme-and-portfolio-management of 5th Edition MSP:

In MSP 5th Edition, the Programme Strategy is a high-level document that outlines how the programme will be directed and managed. One of its vital components is the Design Approach. This section defines how the programme will design its future state, which includes the development of the Vision Statement and the Target Operating Model (TOM). The design approach specifies the methods, tools, and consultative processes (such as workshops) that will be used to ensure the design is robust and meets the strategic objectives.

The statement regarding the facilitated workshop for developing and testing the vision statement is a procedural detail of the "design" phase of the programme. Option C is correct because the vision statement is the cornerstone of the programme's design; it describes the "post-transformation" world. Therefore, the methodology for creating it—including who is involved (senior officers) and who approves it (CEO)—belongs in the Design Approach. While this involves stakeholders (Option B) and decisions (Option D), those are broader themes. The specific activity of forming the vision is a design activity. The Design Approach ensures that there is a structured way to move from the initial mandate to a clear, agreed-upon vision that guides all subsequent tranches and projects.
