"In my experience, project clarity runs the gamut. If you're lucky, every milestone and every role is accurately defined during the scoping phase. At the other end of that spectrum, you may only have an objective, a budget, with very few details. In this situation, I would reach out to the new stakeholder right away. My focus would be to discuss the project at a high level without overwhelming them. I will show them how they are a vital part of the project and clearly explain their role. My second meeting with them would be focused on identifying the different milestones that they will own. Throughout the process, I'll assure them that I will be their main point of contact, should they need information or help in completing their tasks. I will also make sure that communication lines are open between the stakeholders and everyone has eyes on our collective progress."
