What practice involves ensuring that designs are understandable for each group of stakeholders?

The practice that involves ensuring that designs are understandable for each group of stakeholders is primarily captured by requirements specification. This process focuses on clearly documenting the requirements in a manner that is accessible and comprehensible to all stakeholders involved in the project.

Effective requirements specification ensures that different stakeholder groups—such as business analysts, developers, end-users, and project managers—are able to interpret and understand the design and requirements as needed. Each group has different perspectives and needs, and specifications must be tailored to convey the necessary detail and clarity to facilitate this understanding.

While aspects of stakeholder engagement are crucial to gathering and refining requirements, the act of explicitly documenting these requirements in a clear and organized manner is central to the requirements specification practice. This practice includes creating visual models, written documents, and other artifacts that convey the necessary information effectively to all relevant parties.
