For a complex project with a high degree of change, increasing the active engagement and participation of key stakeholders is crucial. This strategy ensures that stakeholders are involved in the decision-making process, which can help in managing expectations, gaining valuable insights, and fostering a sense of ownership among all parties involved. It also aids in identifying potential risks and changes early on, allowing for a more adaptive and responsive approach to project management. : PMBOK Guide - Sixth Edition.
