Non-Functional Requirement Categorization
TEMPLATE
Non-functional requirements often determine a user’s satisfaction with the solution. They detail constraints that are not addressed by other requirements (thus the term “non-functional”). The BABOK® details 15 common categories of non-functional requirements.
Fully specifying non-functional requirements can be challenging. They’re often difficult to measure or test, particularly prior to implementation. They can conflict with each other. They’re frequently captured in text, which can be ambiguous.
Looking for some help? Our guide to non-functional requirements explains each of the common categories and provides examples. We also encourage you to consider attending our Use Case Modeling and Solution Requirements class, which covers this topic in depth.
