10 Software Quality Metrics You Must Know
Measuring software quality is essential for ensuring that the software development process is effective and efficient, and results in high-quality products. The following are ten important software quality metrics that every software development company should consider.
Total Code Churn
Total code churn quantifies the number of lines of code that have been added, modified, or deleted within a codebase during a specific time period, such as a development sprint or release cycle.
High code churn can lead to increased complexity and can make it challenging to maintain code quality, which, in turn, may result in reduced software stability and longer development cycles.
Therefore, it's important to strike a balance between making necessary improvements and minimizing unnecessary code changes to maintain software quality.
Crash Rate
This quality metric measures how frequently a software product experiences crashes. Crashes are instances where the software unexpectedly and abruptly stops working, rendering it inoperable for end users. These crashes often result from unforeseen errors, including defects that may not have been identified during testing, sudden system overloads, or other unexpected issues.
When crashes occur, they disrupt the software's normal operation and can sometimes lead to data loss, causing inconvenience and potential data-related problems for users. A high crash rate is a red flag for any software application.
System Availability
This measures the amount of time a system is operational and accessible to users, typically by comparing the system's uptime (the time it's available) to its downtime (the time it's not available) over a specific time period.
High system availability implies that the system experiences more uptime than downtime, which means users rarely lose access to the system.
This metric directly affects user satisfaction, as downtime can lead to frustration and loss of trust in the product.
Defect Density
This metric evaluates the number of defects, or issues, found in a software product in relation to its size. It's a relative measure that provides insight into the quality of the codebase.
Defects, in this context, are errors or issues that are identified by testers before the software product is released.
A high-quality codebase generally has a lower defect density, indicating that it requires fewer corrections and is easier to maintain, scale, and evolve.
Mean Time to Detect (MTTD)
This metric measures the average time it takes for a software development or support team to identify errors or defects in a software product.
A low MTTD indicates that the team is generally quick at discovering errors in the software.
In essence, a low MTTD is a positive sign of an efficient and responsive development and support process, ultimately contributing to improved software reliability and user satisfaction.
Mean Time Between Failures (MTBF)
This metric calculates the average time between two system failures. These failures can range from critical errors, such as crashes, to less severe issues where the software does not meet end users' expectations.
MTBF is essential for assessing the overall reliability and robustness of software products, especially after their release into production.
It helps in understanding how frequently users may experience issues, and a higher MTBF indicates that the software is more robust and less likely to fail.
Mean Time to Resolve (MTTR)
This metric quantifies the average time it takes for a software development or support team to address and fix an error or issue in a software product after it has been identified.
Typically, MTTR is calculated in terms of hours or minutes, considering only the time that falls within normal work hours (i.e., excluding nights or weekends).
A low MTTR indicates that the team is efficient at resolving errors swiftly.
In essence, a low MTTR signifies that the team is capable of responding promptly to issues, reducing the overall impact of errors, and ensuring a quicker return to normal operations.
Customer Satisfaction (CSAT)
While not a technical metric, CSAT is vital for software success. It measures how customers perceive and experience a software product. CSAT is typically determined by collecting and analyzing data from customer satisfaction surveys.
A higher CSAT score indicates a more positive perception, which means that customers are more satisfied with the product, leading to higher user retention and positive word-of-mouth.
Mean Time to Remediate a Vulnerability
This metric measures the average time it takes for your team to address and fix security vulnerabilities in the software.
A shorter Mean Time to Remediate (MTTR) for vulnerabilities indicates that your team is efficient at identifying and resolving security issues promptly.
This is crucial for maintaining the security of the software and protecting it from potential threats or breaches.
Code Coverage
Code coverage is a metric related to testing. It measures the extent to which the codebase is tested. For high code coverage, programmers must create unit tests that cover every line of code, including various conditions and use cases in the product's functionality. When a software product achieves high code coverage and all unit tests pass successfully, it is an indication of high code quality.
This high code quality, in turn, translates to high-quality software, as it implies that the codebase is thoroughly tested and less prone to defects and issues, ultimately leading to a more reliable and stable software product.
