Final answer:
The user benefits from requirements reuse primarily through improved functional consistency across applications, fewer defects due to tested and refined requirements, and reduced rework which enhances the stability of the user experience.
Step-by-step explanation:
From the user's perspective, the benefit of requirements reuse is primarily related to improved functional consistency across related among a set of business applications. When requirements are reused, the features and functions of different applications become more uniform, helping users to learn the systems faster and navigate between them more efficiently. This uniformity can be especially beneficial in a corporate environment where multiple applications might share common functions or data.
Requirement reuse also tends to lead to fewer defects since the requirements have been previously tested and refined in other projects. This can result in a stable user experience with reduced likelihood of encountering problems while using the application. Additionally, with stable and consistent requirements, there's a lower need for rework, which not only saves time for the development team but also prevents interruptions in the user's workflow.
