The purpose of this Guideline is to show how the COSMIC Functional Size Measurement method (ISO 19761) can be used to specify software requirements in what is called ‘COSMIC Format’. In consequence, the COSMIC measurement is a byproduct of this and hence a separate measurement is unneeded. Moreover, the software requirements texts have a universal pattern and are clear, well-structured and easy accessible.
This Guideline is aligned with the ISO 29148 on Requirements Engineering document.
