EARS would be an effective methodology here. It stands for Easy Approach to Requirements Syntax. In this method, we write clear, concise, and understandable language. This improves the whole requirements engineering workflow and simplifies the work by making things pretty easy to understand.
To achieve this, here are some principles that must be kept in mind while writing the requirements. They involve:
Each requirement must be in the form of a complete sentence. No bullets, acronyms, abbreviations, or buzzwords should be used. Try to make short, direct, and complete sentences.
Make sure that each requirement has a proper subject, predicate, and verb. The subject would be the user type or the system that we are talking about. The predicate would be the conditions or actions or desired results we expect. We must use words like ‘shall’, ‘will’, and ‘must’ to express some kind of necessity, and words like ‘may’ to express optionality in the requirement.
Each requirement must efficiently explain the end result we desire from the system.
Also, the requirement must describe the quality we expect from the system. It helps when we measure the end result and see if the requirement is properly implemented or not.
