The stakeholder management strategy depends on the power and interest of the stakeholder in the project. Harvey's role has changed from Director of Operations to Director of HR, which means his power and interest in the HR project have also changed. When he was Director of Operations, he had low power and low interest in the HR project, so he could be ignored as a stakeholder. Now that he is Director of HR and the sponsor of the project, he has high power and high interest in the project, so he needs constant active management as a stakeholder. Option B is the correct answer.
