See this resource on how you can download a catalog of over 100 well defined quality attribute scenarios. The sixth and final step is to document and communicate the quality attributes and their metrics to the stakeholders and the developers. Documentation means capturing and recording the quality attributes and their metrics and their rationale, assumptions, dependencies, and trade-offs in a clear and consistent way.

  • Security describes the extent to which a system or a component meets that only authorized users are able to access data or services.
  • Testing all aspects of a system by a single testing team takes enormous time and effort.
  • Integrity is the degree to which a software system prevents unauthorized access to a program or data.
  • Most often these are not considered in start-ups or small projects initially.

Example in early television set, you would replace a single vacuum tube, today a whole board has to be replaced. Customizability is the ability of a software to offer extensions to existing functionality to better suite the needs of a user. Security is the ability of the software to remain protected from unauthorized access.

The Importance of Quality Attributes in Software Architecture

In consequence, the system becomes unreliable, hard to maintain, hard to change, and hard to diagnose. Additionally, there is no place and time for making significant changes that would fix the state of the system, because it is hard to allocate those changes to the cost budget. With no surprise, the real cost of maintaining the system grows over time.

This includes determining the cause of errors and understanding the system’s behavior. The modularity quality attribute is the measure of how dividing a system into separate, independent components. This allows each component to be tested, debugged, and modified separately, making the system as a whole easier to maintain. The availability quality attribute is the measure of how the system or a component is to be used when needed. Reliability describes the extent to which a system or a component performs its required functions under specified conditions for a specified period of time.


An example of functional appropriateness would be a system or a component that is tailored to meet the specific needs of its users. Let’s have a look and analyze every quality attributes that are described in the ISO/IEC standard. Software architecture is the foundation of any development software, as it defines how it will be implemented. Quality attributes are an important part of this architecture, as they provide a structure for ensuring that the system meets the desired requirements. They are essential for a system to be robust, reliable, secure, and maintainable.

Having two independent computer systems was expensive, but it was cheaper than not manufacturing their product when the control system was down. Creating a plan and giving the software application or its process the right direction. Happy customers will choose organizations who are renowned for their high-quality software releases.


Nowadays, systems have become very software-intensive, heterogeneous, and very dynamic, in terms of their components, deployment, users, and ultimately their requirements and architectures. Increasingly, systems are deployed on distributed, cloud-based platforms, some diversely situated and interconnected. Multi-tenant systems require supporting diverse users whose requirements may vary, and even change, during use. Adaptive systems need to incorporate various deployment environment changes, potentially including changes in diverse third-party systems. Development processes such as agile methods, outsourcing, and global software development add further complexity and change to software-intensive systems engineering practices. We have added security to our list of the most important software quality attributes as it has lately been the need of the hour.

Most often these are not considered in start-ups or small projects initially. The cost of maintaining the supportability attribute is high, and the result is only visible on a large scale. However, with the growth of the team and the product, this attribute becomes one of the important ones. Testability shows how well the system allows performing tests, according to predefined criteria.

What are Quality Attributes in Software Architecture

Any engineering product is expected to perform at a certain level. Efficiency is an internal quality and refers to how economically the software utilizes the resources of the computer. Usability is one of the most essential attributes, because, unlike in cases with other attributes, users can see directly how well this attribute of the system is worked out. One of the critical problems of usability is too much interaction or too many actions necessary to accomplish a task. Incorrect sequences of steps in multistage interfaces are also a problem of usability. Data elements and controls may be designed not according to the accepted patterns of user experience, which also complicates the interaction.

Functionality, usability, reliability, performance and supportability are together referred to as FURPS in relation to software requirements. A highly available application may trade-off lower performance for greater availability. With data integration, the ways in which the data is used by other applications is pretty much out of control of the original data owner.

Architecture and quality attributes

Correctness can be enhanced by using proven methodologies and processes. Accessibility is the ability of a software to be accessible from a multitude of devices and for a number of different types of users. All AdvOSS Products offer multiple interface each of them is configurable by the Operator.

Software architecture is the foundation that helps building a system that satisfy business requirements. Organizations often think that designing applications consists only of its capabilities and behavior; however, this is a shortsighted perspective. Users are not only affected by the lack of proper functionality but also from the missing required software quality attributes that influence the viability of any software solution. When a system isn’t reliable or secure or scalable, it will inevitably fail the same way as if we forget a critical functional requirement. The next step is to define the quality attributes and their metrics that are relevant for the system and the stakeholders. Quality attributes are the properties or characteristics of the system that affect its behavior or performance, such as availability, reliability, security, usability, scalability, and maintainability.
