Evidence note

ISO/IEC 25040:2024

Technical Standard2024ISO / IEC

What does it cover?

A current ISO SQuaRE standard covering the framework, concepts, requirements and process for evaluating ICT product, data and service quality.

Key points

  1. 1Software quality evaluation is a process rather than merely a list of product characteristics.
  2. 2Evaluation requires explicit requirements, evidence and assessment activity.
  3. 3The standard complements quality-model standards such as ISO/IEC 25010.

Why it matters. Lornets interpretation.

Lornets separates the Framework, what should be examined, from the Methodology, how evidence is collected and technical conclusions are reached.

This is the Lornets reading of the source, not a finding of the source itself.

What it does not establish

  1. 1The standard does not define the complete Lornets methodology.
  2. 2Lornets should not claim formal ISO conformity without implementing relevant standard requirements.
  3. 3ISO content must not be reproduced beyond permitted reference and summary.
