According to the PMBOK Guide1, a hybrid approach is a combination of predictive and adaptive (agile) methodologies that suits the needs and context of a project. A hybrid approach can provide flexibility, customer satisfaction, and risk management benefits. However, it also requires a high level of collaboration, communication, and alignment among the project stakeholders, especially the sponsor and the team.
Therefore, the project manager should train the marketing team on the hybrid approach and keep their director informed of the progress, benefits, and challenges of using it. This way, the project manager can ensure that the team is competent and confident in applying the hybrid approach, and that the director is aware and supportive of the new direction. The project manager can also use this opportunity to address any concerns or resistance from the director and demonstrate the value of the hybrid approach for the project and the organization.
The other options are not as effective as option C. Option A is not realistic, as the marketing director may not have the time or interest to receive formal training on the hybrid approach. Option B is not respectful, as the marketing team members are not in a position to coach their director. Option D is not appropriate, as the project manager is not the director's mentor and cannot assume that role without the director's consent and agreement.
