What aspect is emphasized by defining utility requirements?

Defining utility requirements focuses on the functionality and capabilities that a product must deliver to meet the needs of stakeholders. In ITIL, utility refers to how well a product or service fulfills a specific need or requirement, effectively addressing the question of whether it is "fit for purpose." By emphasizing the fit for purpose, you're ensuring that the product's features align directly with what stakeholders expect and require from it, ultimately determining its effectiveness and value.

While other aspects like aesthetic appeal, financial considerations, and ease of use are important in their own contexts, they do not directly address the core functionality that makes the product suitable for its intended use. Therefore, focusing on utility requirements helps ensure that the primary concerns regarding what the product should achieve are clearly defined and understood, which is critical in delivering value to stakeholders.
