When stakeholders raise concerns despite receiving updates, it suggests there may be a gap in understanding or relevance of the information shared. The project manager should meet directly with those stakeholders to assess the root cause of their concerns and determine whether the plan-or the way it is communicated- needs to be adjusted.
According to the PMBOK Guide - Seventh Edition, effective stakeholder engagement involves not only communication but also actively understanding and addressing their expectations and concerns.
Option B is reactive and narrow in scope.
Option C is Agile-specific and doesn't fully apply if this is a traditional setting.
Option D assumes the communication method is the only issue rather than validating stakeholder input.
