To make the most of ISO/IEC 25010 for quality modeling, it is important to start with a clear vision and purpose for your quality model. Define what quality means for your system and stakeholders, and what are the expected outcomes and benefits of your quality efforts. Additionally, use a stakeholder-driven and user-centered approach to involve the relevant stakeholders and users in defining, evaluating, and validating the quality requirements and characteristics of your system. Moreover, use a modular and hierarchical structure to organize your quality model into layers or levels of abstraction, such as product, process, or in use. Finally, apply the ISO/IEC 25010 standard in a flexible and adaptable way that suits your system and context, and refine and update your quality model as your system evolves.

Quality modeling is the process of creating a representation of the quality requirements and characteristics of a software system. It involves defining the quality criteria, metrics, methods, and tools that will be used to assess and improve the quality of the system throughout its life cycle. Quality modeling helps to align the expectations and needs of the stakeholders, to identify and prioritize the quality issues and risks, and to monitor and control the quality performance of the system.

Using ISO/IEC 25010 for quality modeling can provide several benefits for your software projects, such as establishing a common language and understanding of quality among stakeholders, eliciting and validating quality requirements, selecting applicable quality metrics and methods, comparing the quality of different software products or alternatives, and monitoring and improving the quality of the system throughout its life cycle. This framework can help ensure that quality requirements are aligned with business objectives and user needs, as well as demonstrate the value and impact of quality efforts.

Using ISO/IEC 25010 for quality modeling can be advantageous, however, there are some challenges that need to be addressed. It can be difficult and time-consuming to apply the standard in a tailored way that suits your project scope, size, complexity, domain, technology, methodology, and culture. Additionally, it can be challenging to measure and quantify some of the quality characteristics and sub-characteristics. To balance and prioritize the trade-offs and dependencies among the different quality characteristics, a multi-criteria decision analysis or a weighted scoring technique may be necessary. Lastly, implementing and maintaining a comprehensive and consistent quality model for your system requires significant resources and investments in training, tools, processes, documentation, and governance.

ISO/IEC 25010 is the latest version of the international standard for software product quality. It defines a quality model that consists of eight quality characteristics: functional suitability, performance efficiency, compatibility, usability, reliability, security, maintainability, and portability. Each characteristic is further divided into sub-characteristics that describe specific aspects of quality. For example, usability includes sub-characteristics such as learnability, operability, user error protection, user interface aesthetics, and accessibility. The standard also defines a quality in use model that consists of five quality characteristics: effectiveness, efficiency, satisfaction, freedom from risk, and context coverage. These characteristics reflect the extent to which the software product meets the user's goals and needs in a specific context of use.

ISO/IEC 25010 is a widely used standard for defining and evaluating the quality of software systems. It provides a comprehensive and consistent framework for identifying, measuring, and improving the quality attributes of software products and processes. But how effective and applicable is this standard for quality modeling? What are the benefits and challenges of using ISO/IEC 25010 for quality modeling? In this article, we will explore these questions and provide some practical tips for applying the standard in your projects.
