After sending the team the project management plan, two field engineers asked the next day about their roles and the schedule. What should you have done when communicating the plan?

The best practice for effective communication is not just sending information, but ensuring it's received, understood, and acted upon. By confirming understanding and soliciting feedback, the project manager could have proactively addressed questions about roles and schedules, preventing confusion. Sending the roles and responsibilities matrix is a good step, but doesn't guarantee understanding. Briefing each team member individually before sending the plan is often impractical for larger teams and doesn't replace the need for confirmation. Discussing roles with managers is helpful for their understanding, but doesn't ensure the team members themselves grasp their responsibilities and the schedule.
