Effectively identifying and understanding Non-Functional Requirements (NFRs) is the current frontier in software projects. The models and standards that define them evolve, closely tied to technological advancements. This is a challenge in the field of software measurement. Today, IFPUG SNAP is the first ISO/IEEE standard for sizing these dimensions of software. Now is the time to start collecting historical data for these new sizing units — and a new ISBSG Data Collection Questionnaire (DCQ) is ready to support this effort.

Determining software size is a critical step. This presentation presents an overview of early software sizing techniques available.

Counting examples will be presented in cloud architectures, highlighting critical aspects of functional measurement . This will show their relevance on the accuracy of the results.
