The type of requirements that do not trace to a business need are out-of-scope requirements. Out-of-scope requirements are the requirements that are not related to the project scope, objectives, or deliverables, and that do not contribute to the solution of the business problem or opportunity. Out-of-scope requirements are usually identified and excluded during the requirements analysis and traceability processes, to avoid wasting time, resources, and effort on unnecessary or irrelevant features or functions. Out-of-scope requirements can be caused by various factors, such as unclear or changing business needs, conflicting or unrealistic stakeholder expectations, poor communication or elicitation techniques, or lack of validation or verification methods.
