Fixing these issues early ensures the development team can address them before they become major problems.

Improving development processes

Software quality metrics provide insights into the efficiency of development processes. These metrics help project managers identify bottlenecks, inefficiencies, and areas for improvement.

For instance, code coverage and test case effectiveness can highlight areas where testing efforts can be optimized. This enables organizations to improve development processes, enhance productivity, and deliver higher-quality software products.

Meeting customer expectations

Customers have high expectations when it comes to software usability, functionality, and reliability. Monitoring software quality metrics allows organizations to meet these expectations.

Metrics such as customer satisfaction scores, error rates, and response times provide valuable data on how well the software meets its user’s needs.

Organizations can make informed decisions using this data to enhance their mobile customer experience.

Competitive advantage

In today’s competitive market, your software quality can set you apart. Users are more likely to choose a product that is reliable and efficient.

High-quality software can give you a significant edge over your competitors.

Software metrics help you gauge and improve your functionality, interface, and overall performance, helping you stand out in a tight market.

10 key software quality metrics to focus on

The ISO/IEC 5055:2021 measures the internal structure of a software product through its source codes. It gages software quality based on four factors:

  • Security
  • Reliability
  • Performance efficiency
  • Maintainability

Given the categories and standards mentioned, here are the ten key software quality metrics you should focus on when developing your software product:

1. Code quality

At the heart of any software lies its codebase – a meticulously crafted collection of instructions that govern its behavior.

Quality code is stable, easy to understand, and can be modified without causing application glitches or problems.

Code quality gauges the health of this underlying foundation. It encompasses factors such as readability, maintainability, and adherence to coding standards.

By focusing on code quality, development teams ensure that the software remains flexible, extensible, and robust over time.

2. Reliability

Reliability is the bedrock upon which user trust is built. This metric measures the software’s ability to consistently deliver its intended functionality without unexpected crashes or failures.

Users depend on software that behaves predictably and consistently. Reliability is not only about minimizing crashes. It ensures that the software performs as expected, even under varying conditions.

3. Testability

Testability is the gateway to software improvement. It assesses how easily the software can be tested to identify defects and flaws.

High testability enables efficient testing processes, allowing development teams to detect issues early and rectify them before they escalate. Consider it as the ability to pinpoint a leak in a ship before it turns into a flood.

A high-testable software has five elements:

  • Logging. High-testable systems have effective logs that detail web service commands, who made them, and where and when they happened.
  • Message passing. Testable software has the ability to capture and relay message transfers on demand.
  • Components. Beyond scripting commands, teams must be able to create test servers based on their existing ones through the cloud.
  • Swappable components. Testable systems also have mock and fake components they can remove to isolate a function they will test.
  • Infrastructure. Lastly, testable software has its entire infrastructure as code, which can be tested in a realistic environment.

A software application with low testability hampers the identification of defects, resulting in potentially costly and time-consuming bug fixes later on.

4. Functionality

Functionality is the software’s visible face—the features and capabilities that users interact with. This metric examines whether the software delivers its promised functionalities accurately and efficiently.

Imagine an email application that claims to send messages but consistently fails to do so. Ensuring the software’s features align with user expectations is paramount to user satisfaction and retention.

Functionality testing simulates user interactions to verify that all features work as intended, providing a smooth and reliable user experience.

5. System performance

In a world where speed is a virtue, system performance is a critical metric.  It measures the software’s response time, efficiency, and resource utilization under different workloads.

Users have little patience for sluggish software that lags or freezes.

System performance is not just a luxury. It determines user satisfaction and business success.

6. Defect management

Defect management gauges the software’s ability to handle and address defects effectively. It encompasses defect detection, reporting, prioritization, and resolution.

The ability to identify and rectify defects in a timely manner reduces the risk of catastrophic failures post-launch. Defect management is akin to addressing small leaks in a boat before they compromise its integrity.

By diligently managing defects, development teams ensure that the software remains stable, secure, and reliable.

7. Platform adaptability

The digital landscape is diverse, with users accessing software from various platforms and devices.

Platform adaptability measures the software’s ability to function consistently across different operating systems, browsers, and devices. It ensures that users receive a seamless experience regardless of their preferred platform.

For instance, mobile development teams nowadays are more fond of creating apps for both Android and iOS platforms for flexibility and to help brands gain more user base.

8. Security

Security is non-negotiable in developing an app. Cyber threats such as data breaches loom even in mobile games and utility apps that do not seem vulnerable.

This metric assesses the software’s resilience against unauthorized access and vulnerabilities.

A software application with robust security measures safeguards user data and maintains user trust, contributing to long-term success.

9. Interface accessibility

A user-friendly interface is the bridge between users and software functionality.

This metric measures users’ ability to navigate and interact with the software’s interface. It includes considerations for usability, intuitiveness, and adherence to accessibility standards.

Just as a well-designed storefront attracts customers, an intuitive interface draws users into the software experience. It also encourages engagement and fosters positive user sentiments.

10. Documentation

Documentation is the unsung hero of software development.

It assesses the clarity, comprehensiveness, and accuracy of the accompanying documentation that guides users and developers in using and maintaining the software.

Quality documentation empowers users and developers to understand, troubleshoot, and leverage the software effectively.

Moreover, quality documentation opens the chance for code reusability, allowing the team to build quality software in the future.
