According to Mendelow's stakeholder mapping model, which category requires close management?

In Mendelow's stakeholder mapping model, stakeholders are categorized based on their level of interest in a project and their power to influence it. The categories range from low power/low interest to high power/high interest.

The category classified as high power and high interest (HH) represents stakeholders who have significant influence over the project and are highly invested in its outcomes. These stakeholders are crucial to the success of the project because their needs and expectations can greatly impact how the project is perceived and whether it succeeds or fails. As such, they require close management and effective communication to ensure their needs are met and to mitigate any potential risks associated with their influence.

Effective management of these stakeholders includes engaging them regularly, keeping them informed about project developments, addressing their concerns promptly, and involving them in decision-making processes whenever possible. This proactive approach helps to build strong relationships and ensures that their support for the project is maintained throughout its lifecycle.
