Measuring the Software Product Quality during the Software Development Life-Cycle: An International Organization for Standardization Standards Perspective

Abstract

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 these two standards. Approach: The ISO 9126 on software product quality and ISO 12207 on software life cycle processes had been analysed to investigate the relationships between them and to make a mapping from the ISO 9126 quality characteristics to the ISO 12207 activities and vers versa. Results: This study presented a set of comments and suggestions to improve the ISO 9126. Conclusion: The weaknesses of the crossreferences between the two ISO standards had been highlighted. In addition, this study provided a number of comments and suggestions to be taken into account on the next version of the ISO 9126 international standard.

WaLBerla: HPC software design for computational engineering simulations

“…Software quality is in general hard to quantify [28,29], but there exist standardized software quality factors [30,31]. In this section we investigate our framework with respect to usability, reliability, portability, maintainability, expandability, efficiency, and scalability.…”

Impact of knowledge management on offshore software development: An exploratory study

“…According to [1] as per ISO 9126 standard, quality is defined as ''the totality of features and characteristics of a product or service that bears on its ability to satisfy given needs. Al-Qutaish [3] observed that the ISO 9126 model for software quality and ISO 12207 on software life cycle processes may be analyzed to map the relationships between them for better measurement of software product quality [6] customized the ISO 9126 model to desirable software quality attributes for web applications which are reliability, usability, security, availability, scalability, maintainability, and time to market, Boegh [7] observed that software quality has also been defined in terms of two types of product characteristics: (i) external quality (how the product works in its environment), like usability and reliability, and (ii) internal quality (how the product was developed). According to Andreou and Tziakouris [5] ISO 9126 model, having six major characteristics, namely, Functionality, Reliability, Usability, Efficiency, Maintainability and Portability, along with their associated sub-characteristics can be suitably modified to a quality frame work for developing and evaluating the software components.…”

An approach for performance requirements verification and test environments generation

“…Software performance is considered in many software quality models [5,40]. Synthesizing these quality models, as shown in Table 1, the main aspects of software performance are time behavior [17,31,37], capacity [37], resource utilization [17,31,37], speed/throughput 1 [31] and efficiency [10,17,20,49].…”
