The COSMIC Group has released the Non-Functional Requirements and COSMIC Sizing Practitioner’s Guide (click to download). The purpose of this guide is to:

  • Illustrate that system non-functional requirements (system-NFRs) may be allocated in projects as software functional user requirements (software-FUR);
  • Demonstrate how to specify and measure, using COSMIC Function Points, the functional size of software-FURs that were system-NFRs; and
  • Provide an illustrative example.
