Problem statement: The International Organization for Standardization (ISO) published a set of international standards related to the software engineering, such as ISO 12207 and ISO 9126. However, there is a set of cross-references between the two standards. Approach: The ISO 9126 on software product quality and ISO 12207 on software life cycle processes had been analyzed to invistigate the rel...

ISO/IEC 9126 (1991) established a practical way of decomposing software quality into a set of characteristics and subcharacteristics. Reconciling this approach to quality with a new standard for usability (ISO 9241-11) has led to a comprehensive framework for software product quality which is being incorporated in a revision to ISO/IEC 9126. The new framework defines three perspectives: interna...

Software maintainability has been considered as a main characteristic in many software product quality models. However, these models have different definitions for maintainability and sub characteristics. ISO 9126 is one of the main and most frequently used models in software product quality. This model has been revised and replaced by ISO 25010 as a new model of software product quality. In ad...

Specifying software quality for a product that has still to be developed is difficult for the purchaser or supplier. The purchaser needs to understand clearly and be able to communicate his/her requirements for the product to be developed. The supplier needs to be certain he/she understands the requirement, and is able to assess with confidence whether it is possible to provide the product with...
