The project manager should determine the communication needs, environment, and tools to get the message across to the remote development team. This is part of the Plan Communications Management process, which involves identifying and documenting the approach to communicate most effectively and efficiently with stakeholders1. Evaluating and reassigning the developing tasks to a local vendor who has worked on previous projects (A) is not a viable option since it would disrupt the project schedule, budget, and scope. Documenting the risk in the risk management plan and using contingency reserves to hire a local vendor (B) is also not appropriate since the communication issue is not a risk but a problem that needs to be resolved. Reviewing lessons learned from previous projects and organizational process assets (OPAs) is a good practice, but it is not sufficient to address the current situation. References:
