"My favorite line as a project manager is, 'Do you have everything you need to complete your tasks?' In this situation, I would meet with team member B to understand the roadblocks they are facing. Sometimes, tech-minded people have trouble communicating their needs. They either feel that it makes them look incompetent when they ask for help, or they get territorial about their work. Whatever the reason, I need to be able to sell the benefits of completing the task to team member B. At a personal level, I want to assure them that asking for help or bringing up a problem to be fixed will not be taken against them. In fact, it will become more of an issue if they didn't bring it to my attention immediately. As a project manager, I prefer to be the facilitator, rather than the taskmaster."
