Software functional quality reflects how well it complies with or conforms to a given design, based on functional requirements or specifications. That attribute can also be described as the fitness for purpose of a piece of software or how it compares to competitors in the marketplace as a worthwhile product.

Under this model following characteristics are recognized. Functionality – It evaluates the feature set and capabilities of the program. It is usually related to software code and internal structure. The different software qualities can be measured through various software testing techniques and tools. Following are the different attributes (parameters) that are used to measure the software quality: Testability – How easy it is to test the software and to what extent it can be 2.1 Quality Attributes Software architecture is typically specified in different views to show the relevant functional and non-functional requirements (also known as Quality Attributes) of a software system (Buschmann et al., 2001). Functional requirements deal with a particular aspect of a system's quality attributes that can be predict directly from component properties, from those that need more information, such as usage profile or architecture. Having the means to reason about the qualities of a software design in the same way It has always remained as a challenge for the software architects or designers in coming up with the right mix of the quality attributes with appropriate priority.

Quality attributes of software

A quality attribute (QA) is a measurable or testable property of a system that is used to indicate how well the system satisfies the needs of its stakeholders.In other words, a quality attribute (aka as Non-Functional Requirements) is what makes a system good with respect to a specific stakeholder. Software quality attributes are one of the two types of non-functional requirements. Commonly identified as the software “ilities” (security, availability, scalability, and more), are often considered part of the work that isn’t visible for the users but provides positive value for them. The attributes of quality software in the above categories are as below: Correctness: It means the required functionality and correct results. Customer satisfaction depends on the degree to which customer requirements and expectations have been met.

Having the means to reason about the qualities of a software design in the same way It has always remained as a challenge for the software architects or designers in coming up with the right mix of the quality attributes with appropriate priority. This is further complicated as these attributes are highly interlinked as a higher priority on one would result in an adverse impact on another. Here is a sample matrix showing the inter-dependencies of some of the software quality So as a software architect, you will rely on quality attribute definitions to specify and analyze diverse sets of quality attributes of a given system. The definition is the basis for expressing the quality attributes in a more formal way.
