    Complex Nature of NFRs

    The user-focused nonfunctional classification presented in this course helps an organization combat the subjective, relative, and integrated nature of these vital, yet frequently overlooked requirements.

  • Connector.

    Anatomy of a Nonfunctional Category

    This course describes common nonfunctional categories that apply to software systems. Your organization might determine that additional categories are necessary based on the particular products and services offered. The components of the Anatomy of a Nonfunctional Category provides a simple pattern for developing and defining additional categories beyond those presented.

  • Connector.

    How to Reduce the Risk of Missing NFRs

    Industry challenges contribute to the difficulty of understanding nonfunctional requirements including: no agreed upon complete list of nonfunctional characteristics, no industry-accepted definition of the term nonfunctional, and no single, uniform classification of nonfunctional attributes. This course shares six activities that your organization can apply to save time and money by avoiding the consequences of missed nonfunctional requirements.

  • Connector.

    User-Focused Classification

    Nonfunctional requirements can be classified based on the user’s need for software quality. Addressing a user concern will necessitate the formulation of a number of functional requirements, but the user concerns will also act to constrain other requirements that are characteristic of nonfunctional requirements. User concerns for software quality are grouped under three important aspects: its operational characteristics, its ability to undergo change, and its adaptability to new environments.
