The primary risk addressed by thestakeholder vision milestoneisthat your primary stakeholders agree to your strategy. This milestone ensures alignment and consensus among key stakeholders regarding the project's overall vision, goals, and strategic approach. Achieving this agreement is critical to securing buy-in, support, and commitment from stakeholders, which helps to mitigate the risk of misalignment and conflicting expectations as the project progresses. Other risks, like architectural strategy viability, business case viability, or a realistic release plan, are addressed by other specific milestones or checkpoints in the Disciplined Agile framework.
