Prevention is Better than Cure

By Kara Whitehead, Quality Engineering Manager

In the fast-paced world of technology, businesses are constantly striving to deliver innovative solutions that meet customer needs while staying ahead of the competition. It doesn’t always go to plan.  As we’ve all seen in the media recently, technical glitches, downtime and outages can have a devastating effect on a business.  In the rush to market, it's easy to overlook a fundamental principle: prevention is better than cure. This is where Quality Engineering comes into play, offering a proactive approach that ensures superior quality and performance from the outset.

The Cost of Reactive Measures

When issues are addressed only after they arise, the costs can be staggering. According to various industry studies, the cost of fixing a bug after release can be up to 100 times more than addressing it during the development phase. These costs are not just financial. Delayed releases, dissatisfied customers, and tarnished brand reputations are significant risks that can have long-lasting impacts on a business.

The Proactive Approach of Quality Engineering

Quality Engineering emphasises prevention through rigorous testing, validation, and continuous improvement throughout the SDLC (software development lifecycle), and can transform delivery resulting in better quality outcomes.

• Early Detection and Resolution of Defects - Implementing automated tests early in the development process helps identify and resolve issues before they escalate. This continuous testing ensures that each component functions as intended and integrates smoothly with others.  Regular code reviews and the use of static analysis tools help catch potential issues early, ensuring that the codebase remains clean and maintainable.

• Enhanced Collaboration and Communication - Quality Engineering fosters collaboration between developers, testers, and business stakeholders. This integrated approach ensures that quality is a shared responsibility, leading to more robust and user-centric solutions.

• Risk Management - Prioritising tests based on the potential impact and likelihood of defects helps focus efforts on critical areas, ensuring that the most significant risks are mitigated.

• Continuous Improvement - Tracking quality metrics such as defect density, test coverage, and mean time to resolution provides valuable insights into the development process. These metrics help teams identify areas for improvement and implement best practices.  Incorporating feedback from users and stakeholders helps refine and enhance the solution continuously, ensuring that it evolves to meet changing needs.

Despite the traditional view that testing is a discrete phase occurring at a certain point in the SDLC, there’s a fast-growing base of professionals who recognise the true potential of QE, and how, by looking at quality more holistically, and integrating testing throughout the entire SDLC, driving continuous improvement, and embedding quality practices from the outset, outputs are more reliable, secure, and meet customer expectations.

In the realm of delivering technology, the adage "prevention is better than cure" holds true. By embracing QE, I truly believe that businesses can proactively ensure that what their technology is of the highest quality, meeting and exceeding customer expectations while minimising costs and risks. In an industry where reliability and performance are paramount, investing in quality is not just a good practice—it's a competitive necessity.

See you at the National Software Testing Conference?

I’m looking forward to going to the National Software Testing Conference this week.  It’s an event for any professional aligned or interested in Software Testing, Quality Assurance and Quality Engineering, so I’m sure I’ll get into some healthy discussions.   If you're planning to attend and are interested in having a chat, drop by the Roq stand and say hello.

P.S. Our CEO Stephen Johnson, another founding signatory of The Quality Engineering Charter, will also be delivering a speaker session on Maximising Value Through Quality Engineering with the Quality Engineering Charter, alongside other signatories, Michelle Christmas and Adam Rockliffe. Be sure to listen out for it!
