The most appropriate next step is to proactively engage the new, influential stakeholder. A one-on-one interview allows the project manager to understand the senior manager's perspective, expectations, and experience. It also provides an opportunity to brief them on the project's current objectives, scope, and plan. This alignment is crucial before the kick-off meeting to prevent disruptions, build a positive working relationship, and ensure the new member can contribute constructively from the start. This action exemplifies effective stakeholder engagement, a key responsibility of the project manager.
