Pattern-based refinement of unbounded requirements

摘要: There are several requirement types that have been recognized by requirements engineering. We propose a new type of unbounded requirements. Unbounded special functional requirements, which can only be partially satisfied. provided vast evidence their existence; illustrated the notion on examples retrieved from various applications such as Spotify, PopcornTime, Nimble, Salesforce, OneDrive for Business, Firefox, Skype and PicCollage. This has further evaluated interviewing field experts existence confirmed. While there is small amount awareness about in practice, these interviews uncovered hard to implement address they considered standard By addressing we uncover criteria satisfaction might otherwise neglected. satisfied fully.
