Bad software is like a traffic jam—it is awful, frustrating, and inescapable. “Why can’t this program just work?!” is the same as, “Why can’t these cars just move?!” In other words, those who are responsible for software quality carry a big weight on their shoulders. In an article at DZone, Cagdas Basaraner shares software quality factors that you should keep in mind to avoid trapping and frustrating users:
- Flexibility and extensibility
- Maintainability and readability
- Performance and efficiency
- Availability, robustness, fault tolerance, and reliability
- Usability and accessibility
- Platform compatibility and portability
- Testability and manageability
- Functionality and correctness
Happier Software Experiences
Alright, that list covers a pretty broad blanket of factors, but that goes to show the reality of how complex making great software is. Software needs to be flexible enough to withstand additions or removals to its functionality without demolishing the rest of the system. It needs to move quickly enough to appear that it is making smart use of resources. And it should be supported by clear and meaningful documentation.
Of course, in the end, software quality depends upon robust testing:
Source code should be tested with the most coverage and with the most efficient testing methods. This can be performed by using encapsulation, interfaces, patterns, low coupling etc. techniques correctly. Besides testability, a qualified software should be manageable after deployment. It may be monitored for e.g. performance or data usage status, or may enable developer to configure system easily. Creating a successful logging system is another very important issue about managability[sic].
Although, no matter how well-constructed the software, quality becomes a moot point if the software does not abide by the requirements that the business laid out in the first place. It is thus important to be continuously incorporating feedback to keep software development on track.
