Therefore, identifying and solving bugs at an early stage is crucial. It helps in boosting the efficiency of the software at reduced costs. On the other hand, not testing early leads to poor software quality and exacerbates problems that are not only expensive but also time-consuming.

This article explains in detail 15 tried and tested strategies to improve software quality.

What is Software Quality Management?

Software quality management entails the process of ensuring that the final product works as intended and meets customer satisfaction requirements. SQM processing features activities such as quality assurance, planning, and control. Therefore, a poor software quality management (SQM) process results in low adoption rates.

Poor SQM processes affect the reputation of companies, lowers employee morale, and may lead to the development of errors or complications when releasing patches and updates. The best way to gauge SQM standards is maturity level and by using Testing Maturity Model (TMM) software services.

15 Strategies to Improve Software Quality

Listed below are 15 strategies that will drastically improve software quality.

1. Test Early

Testing is important when learning how to improve software quality and shouldn’t be neglected. Testing aims to catch defects early during the design phase so they don’t snowball and grow into bigger issues later. Software development teams resort to manual testing for many problems, but companies leverage automated testing strategies for non-UI tasks.

Testing early also invariably reduces the money spent on bug fixes. A defect that could cost your company $100 in the requirements phase can cost $10,000 or more in the product implementation stages.

2. Implement Cross Browser Testing

Cross browser testing checks if the software runs seamlessly across different web browsers, screen sizes, and mobile apps. With multiple devices and models coming out in the market, cross browser testing is becoming integral for every developer. There are many upsides associated with cloud-based cross browser testing, and effective testing solutions lead to a flawless user experience.

You can cut costs, optimize the speed and performance of your products, and ensure that testing environments stay scalable and dynamic using various cross-browser testing tools. For best results, combine parallel testing and testing automation tools.

3. Test on Multiple Devices

Multi-device testing will help you make better decisions regarding software development and quality improvement processes. There is an overwhelming number of devices, screen sizes, and OS configurations in the market, so it’s important to test as many variations as possible.

Windows and Mac are the two most popular operating systems used for testing purposes, and web browsers such as Chrome, Safari, Opera, and Firefox cover most of the users. Using the same configurations as end-users when testing software on these browser and OS environments is vital. Testing tools like BrowserStack gives developers access to real-time environments without having to install additional hardware on machines.

4. Optimize Automation Testing

Increasing adoption of Automated testing and Agile methodologies has led to improvements in software quality. According to a 2020-21 World Quality Report, automation testing tools can save time, enhance coverage, minimize human errors, and improve testing capabilities. Some popular approaches are smoke testing, regression testing, cross-device and cross-browser testing, and load testing.

There are various automated testing tools, and it’s critical to strike a balance between manual and automated testing methods. Most automated testing solutions can be integrated with Agile workflows and be a core component of DevOps practices.

5. Use Quality Controls from the Beginning

Quality management and control is an ongoing process, so testers must cooperate with developers and work together. A structured approach effectively improves test processes and cuts maintenance costs with native testing tools.

6. Leverage Continuous Delivery (CD) and Continuous Integration (CI)

CI-CD requires engineers to integrate changes and improvements to every step of the software development lifecycle. Continuous Delivery focuses on releasing changes to customers interactively, while continuous integration makes code more dependable by integrating modifications to a product multiple times daily.

7. Have Clear Communication

Clear communication with all team members is integral to the software quality improvement process. Having consistent KPIs (Key Performance Indicators) throughout the project and conveying accurate test reports helps in communicating. Everybody should be aligned when setting testing requirements and sharing feedback. It’s critical to get all stakeholders involved in meetings and ensure team members communicate with vendors and do not work in isolation.

Fluid communications can prevent project risks, ensure that processes run smoothly and that the software quality goals of senior management teams are met. Teams can use popular messaging apps like Slack, Discord, and Telegram for seamless communication.

8. Create a Risk Registry

Risk management is critical to software quality improvement, and project managers know they must monitor risks throughout the development lifecycle. A project risk register is also called a risk log, and it is used to identify, track, and analyze potential risks. Your team members should create a risk registry to record these risks, assess them, and assign appropriate priority levels for effective mitigation.

Examples of risks logged include:

  • Legal compliance and regulatory risks
  • Data security and breach risks
  • Unforeseen events such as natural disasters, physical break-ins, and theft
  • Supply chain disruptions

A risk register comprises the following elements:

  • Identification number (for risks)
  • Brief description and overview of each risk
  • Risk categories (both internal and external)
  • Probability
  • Impact and Rating
  • Risk analysis approach and specification
  • Action plan
  • Names of individuals responsible for overseeing, managing, or mitigating risks

9. Document Your Project Requirements

Good documentation defines the scope of the project, milestones, deliverables, and technical specifications, thus ensuring you meet deadlines and stay on track. The documentation also defines customers’ needs and lists functional and non-functional requirements.

More importantly, it contains a list of all important features and processes with step-by-step breakdowns that help keep track of the development process. The first step to creating effective documentation is communicating to clients and collecting information about their expectations. All development processes and plans should follow the documentation based on them.

10. Think Outside the Box

Promoting innovation and thinking outside the box should be a no-brainer. Simply copying your competitor’s strategy or growth hacks isn’t enough. People crave “different,” and you will stand out if you build a unique product that others cannot replicate. To improve software quality, think about what you stand for. Automate monotonous processes to free up time for productive tasks and use quality metrics with your testing structures.

11. Incorporate Employee Training

Your employees can play the role of your end-users. Tools, technologies, and techniques evolve, and it’s important to stay on track with the latest trends. Employee training instills an awareness of what to look out for in leading software products. Flaws and vulnerabilities your team normally wouldn’t notice during user journeys will crop up. Employees should also work on upgrading their coding skills to contribute to the software development process.

12. Create a Quality Management Plan

A quality management plan (document) outlines software quality expectations, defines roles and responsibilities, supports project managers, and organizes tasks to ensure that software development matches customer requirements and expectations. It has key components such as reporting tools and assurance policies, quality standards, testing strategies, and software quality objectives. Think of it as a roadmap for future improvements with the foundation set in stone.

13. Do Formal Technical Reviews

In a formal technical review, the stakeholders meet and discuss the logical and functional errors of a software program. These review rounds require a team of engineers and entail preparing reports for presentations.

The main objective is to give all reviewers a product walkthrough, examine source code, detect bugs, and make additional inspections. These reviews improve the software quality and help keep developers accountable for the production management process.

14. Try Ad Hoc and Exploratory Testing

Ad hoc and exploratory testing go into the manual side of testing. The main idea is to explore creativity and push the boundaries of testing practices. There are no rules to this, and exploratory testing is conducted on the fly at any moment. This approach benefits developers in testing software usability and user behaviours.

Ad hoc testing uses random data to generate tests and aims to break or disrupt software services. Its objective is to find vulnerabilities and is usually done near the end of the development process.

15. Produce Bug Reports

A good bug report can make software testing and improvement highly effective. It includes all possible scenarios, and use-cases and describes behaviours exhibited while testing new features. You can add screenshots of failure exceptions in the report, list all possible solutions, and a bug summary.

To develop high-quality software and ensure optimal performance, it’s important to have stringent software quality measures in place. Extensive testing across different environments using various methodologies is an effective way to improve software quality. 

Making good quality software is not a black and white affair but a constant ongoing process. As a developer, you should be willing to make multiple iterations and additional tweaks based on analysis and feedback gathered in the quality management process.
