Key Takeaways:
Elements of Quality
The definition of quality varies based on different perspectives. Let’s now explore how the Quality Attributes of a product or application can be evaluated.
Software Development Quality is measured using the following elements. Each attribute is employed to assess product performance. These attributes are used for both Quality assurance and Quality control.
Quality Assurance actions aim at preventing defect occurrence, whereas Quality Control actions target identifying faults in products and services.
#1) Reliability
Determine if the product is trustworthy enough to withstand different conditions. It should consistently provide precise results. Product reliability is gauged by evaluating its operation under varying environments and scenarios.
#2) Maintainability
Different versions of the product should be easy to manage. To enable smooth development, it should be easy to extend the existing codebase, periodically update features, and adapt new technologies.
Maintaining the system should be straightforward and economical. The software should be easy to amend and correct flaws.
#3) Usability
This is gauged based on the ease of use. The application should be user-centric and easy to learn with simple navigation.
The system should be:
- Easy to operate for input preparation and output interpretation.
- Integrate consistent user interface standards and conventions with other frequently used systems.
- User-friendly for new or occasional users.
#4) Portability
This is assessed through the Cost-related factors of porting, Technical issues related to porting, and Behavioral factors relevant to porting.
#5) Correctness
The application should operate correctly in terms of functionality, internal calculations, and navigation. This indicates that the application complies with functional requirements.
#6) Efficiency
It is among the key system quality attributes. It’s assessed by the time needed to complete an assigned task by the system. For instance, the system should use the processor capacity, disk space, and memory resourcefully.
The system’s performance degrades if all available resources are in use, thereby failing efficiency tests. If the system lacks efficiency, it cannot be applied in real-time applications.

#7) Integrity or Security
Integrity is often tied with security. The system’s integrity and security need to be strong enough to prevent unauthorized access to system functions, data loss, virus infection, and to protect data privacy.
#8) Testability
Testing the system and identifying faults should be easy. If needed, it should be easy to split into different modules for testing.
#9) Flexibility
The system should be adaptable and flexible enough for changes. It should easily interface with other standardized third-party components.
#10) Reusability
Software reusability is a cost-effective and time-saving development strategy. Different code library classes should be sufficiently generic to be applied across different application modules. The application should be split into distinct modules for reusability across the application.

#11) Interoperability
For a product, its interoperability with other systems should be easy to facilitate data or service exchange. Different system modules should work on different operating system platforms, databases, and protocol conditions.
Wrapping Up
By applying the above-mentioned quality attribute standards, we can assess whether the system fulfills quality requirements or not.
All these attributes are pertinent to the QA and QC processes, enabling both the tester and the customer to evaluate the quality of the application or system.
