Explanation
The project manager should empower and coach the team members to focus on project delivery results, as this is one of the core values and principles of agile project management. According to the Agile Practice Guide, the project manager should create an environment of trust, collaboration, and experimentation, where team members are empowered to make decisions, take ownership of their work, and deliver value to the customer.
The project manager should also coach the team members to adopt an agile mindset, embrace change, and continuously improve their processes and practices. Following company procedures and retraining team members on the agile approach (A) is not the best option, as it may not address the root cause of the problem, which is the lack of empowerment and coaching. Identifying key team members who can influence others to contribute efficiently (B) is not enough, as the project manager should also provide guidance and support to the whole team, not just a few individuals. Asking company management to delay the project and grant it additional time (D) is not a proactive or effective way to improve the situation, as it may increase the cost and risk of the project, and reduce the customer satisfaction and trust.
