Agile promotes continuous improvement and collaboration. However, if a new process affects key stakeholders outside the development team (in this case, the business), then alignment is required. The project manager should engage the business manager and discuss the proposed approach and its benefits to secure approval.
The Agile Practice Guide supports direct stakeholder engagement when process changes affect external contributors or consumers of deliverables. Agility includes openness to improvement, but also emphasizes communication and stakeholder buy-in.
Option B (PMO) may help, but the business manager is the decision-maker.
Option C delays potential value.
Option D ignores required alignment with business stakeholders.
