How to Measure Software Quality

On June 22, 2022 / By Admin

The overall quality of the software is more crucial than ever in today’s digital economy, which places a premium on the use of software in all aspects of the organization. Customer satisfaction, increased revenue, and increased profitability are direct results of high-quality software. An organization can more readily enter new markets with established market demand and a well-thought-out business plan.

On the other hand, having low-quality software can be one of the quickest ways to fail, even with the most robust business plan. This is one of the fastest pathways to failure.

Regarding software quality, leaders can’t afford to cross their fingers and hope for the best. Businesses need to assess the quality of their software in the same way they measure market trends, sales pipelines, inventories, fulfillment, and other aspects of their operations.

What Are Software Quality Metrics?

Software quality metrics are essential tools that can help you understand and improve many aspects of a project. Suppose you are developing new software and want to know how to effectively organize everything and evaluate the quality of the product before it is released. In that case, software quality metrics can help you do both.

Although metrics do not directly contribute to development, managers utilize them to understand better how the production process works. Metrics describe what is going on throughout the project by presenting statistics on all aspects of the process. Without this information, managers will have difficulty identifying problems and developing solutions.

The quality of software can be evaluated using one of several different metrics, all of which are available. Nevertheless, there are a few metrics that are particularly beneficial and are necessary for measuring the quality of software. These are –

  • Code Quality
  • Reliability
  • Performance
  • Usability
  • Correctness
  • Maintainability
  • Integrity
  • Security

Now, let’s get a better understanding of each quality statistic in greater depth:

Code Quality – It is essential for premium software to have code that is error-free and correct conceptually. Code quality standards are divided into quantitative and qualitative metrics. Quantitative quality metrics evaluate aspects of software such as its size or level of complexity, the number of lines of code and functions it possesses, the number of errors that occur for every 1,000 lines of code, and other aspects. Measuring the maintainability, readability, clarity, efficiency, and documentation of a piece of code are some qualitative code quality metrics. These metrics determine whether or not the code is easy to read and comprehend and whether or not it is written according to coding standards.

Reliability – Metrics of reliability express the degree to which software is reliable under various circumstances. It is determined whether the program can provide accurate service at the appropriate moment. Mean Time Between Failure (MTBF) and Mean Time To Repair (MTTR) are two methods that can be used to evaluate reliability.

Performance – This facet of the software is referred to as “Efficiency” in the CISQ software quality model. How an application’s source code is written, the application’s software architecture, and the components that make up that architecture, such as databases and web servers, are typically the most critical factors that contribute to the application’s performance. Scalability is another important aspect of performance. Systems that can scale up or down are better positioned to adapt to varying levels of required performance.

Usability – Because every piece of software is designed with the end-user in mind, one of the essential measures of a program’s quality is whether or not it is intuitive and easy to use. Metrics for usability determine whether or not a program is designed to be user-friendly. The person who uses the software is known as the end-user. Therefore, it is essential to determine whether or not the software’s final consumer is satisfied with its performance.

Correctness – Correctness is one of the key metrics for measuring software quality since it determines whether a system or piece of software is operating correctly and free of errors to fulfill the end user’s requirements. The level of correctness reflects each function’s service as per the developed standards.

Maintainability – The ease with which software may be modified for different purposes, the degree to which it is portable between environments, and the extent to which it can be transferred from one development team to another or from one product to another are all aspects of software’s maintainability. The quality of the code has a strong influence on maintainability. It is expected that software will be easier to maintain if the code is high quality.

Integrity – Software integrity is significant in terms of how easy it is to interface with other required software, which increases software functionality, and how much control there is over integration from illegal software, which raises the likelihood of cyberattacks.

Security – When discussing the quality of software, the concept of security refers to how likely it is that malicious actors would be able to breach the software, either by interfering with its operations or by gaining access to sensitive data due to bad coding techniques and architecture. One of the most important ideas in security is that of “vulnerabilities,” which are problems that are already known to exist and have the potential to lead to a security breach. One of the most crucial indicators of a system’s level of security is the number and severity of the vulnerabilities that have been discovered in it.

The Bottom Line

You shouldn’t forget how important having high-quality software is for your business. As a result, you want to place a greater emphasis on acquiring quality measurements, making it possible for you to regulate newly emerging programming faults continuously. Currently, the quantity of software products available on the market is not as important as the quality of such goods. Additionally, ensure that you follow up on fresh user input regarding the software requirements and their wishes.

When it comes to software development management, metrics may be of great assistance because they provide information on the quality of the code, the productivity of the team, and the areas in which there is room for improvement. If a project manager does not have access to relevant data, it may be challenging for them to evaluate the performance of a development team and identify problems.

Metrics allow you to continually uncover new ways to improve the product and support more efficient development.
