According to the PMBOK Guide, 6th edition, section 13.2.2.4, stakeholder engagement assessment matrix is a tool that can be used to identify the current and desired levels of engagement for each stakeholder or stakeholder group. The project manager should use this matrix to plan and implement appropriate strategies to increase the support and minimize the resistance of the stakeholders. One of the strategies is to meet with the stakeholder and discuss the impact of the project deliverable on their interests, needs, and expectations. The project manager should also explain the benefits of the deliverable for the organization and the stakeholder, and address any concerns or issues that the stakeholder may have. By doing so, the project manager can increase the stakeholder's awareness, understanding, and involvement in the project, and foster a positive relationship with them.
