The project charter was approved and the sponsor authorized work to proceed. The program manager confirms a requested key resource is also needed on another project at the same time, which will affect delivery. What should the project manager do?

The project manager should meet with the project manager of the other project to find a resource optimization solution. This proactive approach demonstrates collaboration and problem-solving, aiming to find a mutually beneficial solution without immediately escalating or impacting the client. Resource optimization techniques, such as resource leveling or smoothing, can be explored to ensure both projects can progress effectively. Paying overtime is not a sustainable or guaranteed solution and may not be within the project manager's authority or budget. Requesting a deadline delay should be a last resort after exploring internal solutions. Asking the program manager to prioritize one project over another can create conflict and may not be feasible or fair to other projects.
