Software quality should be a very important part of your business and shouldn’t be overlooked. According to CISQ, in 2020 just in the USA reported impact of poor software quality was £1.75 billion.
It is as important if you have an in-house software development team or youre outsourcing your software development.
The good news is that we can monitor and drastically lower our contribution to this worrying statistic by implementing a few software quality indicators.
“If you can’t measure it, you can’t improve it”, as Peter Drucker famously stated.
But tracking too many metrics can be a trap itself, because they may be obstructing your field of view.
What are software quality aspects?
Each individual and every organization has different requirements for what constitutes a good measurement tool or aspect. What is significant to one person might not be significant to another. Additionally, as mentioned using too many metrics not only wastes time but also complicates the final product.
The same idea holds true when we consider software quality measurements. You must make sure that all of your products and code are of high quality because businesses are moving more and more toward an agile and rapid software delivery cycle. The issue is found there.
Faster software deployment and marketing often require “flying blind,” which may cause quality to suffer for lack of time. Since metrics are subjective and largely dependent on the audience, one software firm might emphasize the number of bugs discovered, and another one concentrates more on failure rates.
In general, the goal is to prevent any harm to your software. To achieve that, you must locate a reliable software quality metric system.
Software quality aspects that are most often looked after are:
Reliability. You may determine how effectively the software will function and how long the system will function without crashing by examining the number of flaws. A low defect count is particularly crucial if you wish to have a strong codebase.
Maintainability. Is maintaining your software a challenge? Let’s discover utilizing the codebase analysis metrics for structure, size, complexity, and consistency. Examining testability and understandability is equally crucial.
Testability. What degree of testing support does the product provide? Depending on how well you automate, isolate, control, and monitor the testing process.
Portability. It demonstrates whether the software can be used in different settings. Although there are some ways to achieve it, there are no tools that can show the project’s portability. Testing the code early on, before development is complete, is the recommended course of action.
Reusability. Use metrics that count the interdependencies to determine whether you can reuse assets like code. The availability of modularity or lose coupling determines the reusability.
Software requirements
Software requirements, which are frequently used to explain how customers want the software product to behave, are classified as either functional or nonfunctional by experts as a “description of features and functionalities of the target system.”
Functional requirements
Basic software system inputs, actions, and outputs. The anticipated behavior – calculation, data manipulation, user interaction, and more is understood using these requirements. The software is not functioning if these actions do not take place.
Non-functional requirements.
The visual portrayal of criteria used to evaluate software systems’ efficacy (aka quality). Non-functional requirements, which define how a system should function while addressing the majority of criteria used to assess software quality, include things like rate of recovery, privacy, usability, and more.
The importance of software quality metrics
It is best to concentrate on end-user requirements and the value they derive from the software after considering how metrics are defined in relation to value. You may utilize metrics to assess, alter, and improve the process over time, assisting your team in producing greater value. Creating a value cycle for quality from beginning to end will ultimately:
- Increased revenue
- Save money and time.
- Encourage the use of agile software development methods
- In other words, it addresses the issue of coders just focusing on the software as it is being developed and ignoring further evaluation of the finished product or the user’s perspective.
7 metrics to ensure software quality
The following principles or factors are things that can be measured. Then use the results to test the quality of your software as it applies to the above quality aspects trying to be achieved.
The number of files, lines, etc. What impact do file sizes have on software? What purpose do the code lines serve? Do you have manageable numbers?
Field bugs What issues are there with the software that is already running? How many production-related bugs did you find? Your software’s dependability Over a certain period of time, how many times did it fail?
Code churn Why does one section of the code run more frequently than others? Why is it prone to errors? Is there anything unusual about the completion rate? Is the churning code still usable?
Results of static analysis. What aspect of the software is consistent? How long does code maintenance take? In light of what has changed, is the software secure as it currently stands?
Bug arrival rate. How are bugs being discovered? When did a bug first appear? What led you to believe that the software was prepared? What is the rate of the invasion of bugs? How many software releases took place in a period?
Performance. Do updates affect the software code’s durability? Is it operating as it should? Why doesn’t it work when tested for load, stress, or response? Does it appeal to users?
Test failures.What tests, both manually and automatically, fail? Was the test successful before it failed? How many failures have you had? What technological improvements can be made to testability?
We will produce high-quality software regardless of the quality criteria that are crucial to you and meet all your requirements. Our engineers can help you get the product you want for a reasonable price in the shortest time really possible.
