A Power / Interest Grid is a technique for analysing and managing stakeholders based on their level of power and interest in an organisation or project. It helps to identify who are the key stakeholders and how they should be engaged and communicated with. Therefore, option B is the correct answer, as a Power / Interest Grid would help the business analyst to gain an understanding of who the stakeholders are, how much authority they have, and how much involvement they want in the project so that a stakeholder management plan can be created. A Power / Interest Grid would help to classify stakeholders into four categories based on their level of power and interest: high power, high interest; high power, low interest; low power, high interest; low power, low interest. A Power / Interest Grid would help to determine different stakeholder management strategies for each category: active and constant management; keep satisfied; keep informed; watch. Option A is not a correct answer, as CATWOE is not a technique for analysing and managing stakeholders based on their level of power and interest. CATWOE is a technique for exploring stakeholder business perspectives by identifying six elements: Customer, Actor, Transformation, Worldview, Owner and Environment. It helps to understand how different stakeholders perceive a business situation or problem and what they expect from a solution. Option C is not a correct answer, as RACI chart is not a technique for analysing and managing stakeholders based on their level of power and interest. RACI chart is a technique for defining roles and responsibilities of stakeholders in relation to tasks or activities within an organisation or project. It helps to identify who are Responsible, Accountable, Consulted or Informed for each task or activity. Option D is not a correct answer, as resource audit is not a technique for analysing and managing stakeholders based on their level of power and interest. Resource audit is a technique for identifying and evaluating the resources that an organisation has or needs to achieve its objectives. It helps to assess the availability and quality of an organisation’s resources, such as human, physical, financial and intangible resources.
