A Feature is a service that fulfills a stakeholder need and delivers business value. One key component of a Feature is the benefit hypothesis, which is a statement that describes the expected outcome and value of the Feature for the end user or the business1. The benefit hypothesis helps to define the scope, priority, and acceptance criteria of the Feature, and to measure its impact and effectiveness after implementation2. The benefit hypothesis also supports the Lean UX process model, which includes a definition of the Minimum Marketable Feature (MMF), a benefit hypothesis, and acceptance criteria3. The other options are not key components of a Feature, although they may be related to it. A business plan is a document that outlines the goals, strategies, and financial projections of a business or a product, and it may include some features, but it is not a component of a Feature. Key stakeholders are the people or groups who have an interest or influence in the product or the Feature, and they may provide input or feedback, but they are not a component of a Feature. A release plan is a schedule that shows when the product or the Feature will be delivered to the customers or users, and it may depend on the Feature, but it is not a component of a Feature. References: Features and Capabilities - Scaled Agile Framework, What Are The Minimum Requirements For A Feature?
