There’s been a ton of digging around to understand why software projects stumble and fall. One of the most common hurdles is not prioritizing quality assurance during the development process. And even tiny errors that slip through the net can lead to big financial hits.
The importance of QA
The path to crafting top-tier software? Put in place effective QA management, equipped with the right tools and methods for creating a bug-free product. The term ‘software quality management’ actually encompasses three key areas:
- Quality assurance
- Quality control
- Testing
And trust us, they’re all just as important as the next.
Software Quality Assurance (SQA) is a key facet of quality management that encapsulates a strategically planned assortment of organizational actions. Its goal is to enhance the software development process and instill quality standards that keep glitches and bugs at bay.
Software Quality Control (SQC), another vital piece of the quality management puzzle focuses on meeting quality requirements. It revolves around product-oriented activities that vet software products for their quality, pre-release.
Testing is the fundamental action directed at spotting and ironing out technical hitches in the software’s source code, while also evaluating the product’s overall usability, performance, security, and compatibility.
- A great cautionary tale about the importance of QA is the story of Flud, once hailed as the “first true social newsreader.” This app, designed for iPad, iPhone, Android, and Windows Phone, came undone because of inadequate QA. The Flud squad was all about developing and coding, almost to the point of neglecting everything else. By the time the product hit the market, it was crawling with bugs and packed with discrepancies. Sure, they eventually fixed everything, but by then the damage was done. The app’s poor reputation and terrible user experience meant it was doomed to failure. And so Flud was discontinued.

Create a testing and QA roadmap
Testing and QA procedures ought to be systematically charted, defined, and logged. Great documentation is the magic wand that cultivates effective communication within your software squadron. So, let’s deep dive into a few key documents that fuel the QA journey.
- Test Policy: Think of this as your QA manifesto, outlining your company’s testing principles, objectives, and how testing is performed. This comprehensive guide encompasses the essence of testing for your organization, software testing standards for projects, testing terminology, tools aiding testing, methods to measure testing efficiency, and ways to upgrade testing processes.
- Quality Management Plan: This blueprint indicates an acceptable quality level for your product and outlines how to achieve it. Its aim is to keep your project management on track by defining roles, responsibilities, and quality standards. It outlines the software’s quality requirements and details how they will be assessed.
- Test Strategy: As a tactical document derived from business requirements, a test strategy defines software testing methods to accomplish testing objectives. For larger projects, it’s developed as a separate document from which each test plan can be advanced.
- Test Plan: It provides an overview of what, when, and how to test, outlining the testing scope, activities, objectives, and helping mitigate risks. A well-crafted test plan includes a schedule for all necessary testing activities and clearly defined team roles.
- Test Cases: They’re sets of input values, execution preconditions, expected results, and execution postconditions, developed for a specific testing goal.
Adopt a test-centric software development approach
Revamping your development approach to be more test-oriented can significantly boost the quality of your software. One way to do this is extreme programming (XP), a methodology centered on enhancing software quality and flexibility to adapt to changing requirements.
Let’s then focus on two XP practices related to testing:
1. Test-driven development
TDD flips the script by having tests written before any code implementation. It’s a test-first methodology that emphasizes a short development cycle, starting every new feature with a written test. Initially, such a test fails because the code isn’t developed yet, but the next step involves writing code that corresponds to the test, passing it successfully. Lastly, the code is refactored until all tests are passed, and the benefits are a higher quality product, cost-effective debugging, simplified code, and increased productivity.
2. Pair programming
Two heads are better than one, right? That’s the essence of Pair Programming, an extreme programming technique that involves two developers working on the same code. One writes the code (Driver) while the other (Navigator) gives suggestions and guidance. Roles can be swapped at any point. As a result you have superior code quality, lesser bugs, better knowledge sharing, and more streamlined code. This pair-based approach can also be applied to testing, fostering a brainstorming environment that increases productivity and results in a higher quality product.
Test early & often with a shift-left approach
The shift-left testing approach is a game-changer, as it urges you to kick-start testing activities at the onset of the development process, instead of relegating it to the last stage, as traditional methodologies often do. It involves:
- Planning Ahead: Never leave testing to the last minute. It can result in bottlenecks and hamper progress. Incorporating a testing schedule from the start can nip bugs in the bud and ensure smooth functionality.
- Reviewing Requirements: Engage testers in conversations with customers and stakeholders, facilitating a deep-dive into requirement analysis.
- Frequent Testing: Run smaller, frequent tests throughout the development stages, enabling immediate validation and system improvements.
- Test Automation: Automating tests where possible and ramping up test coverage can speed up and enhance the testing process.
- Prevention over Reaction: Focus on preventing problems rather than fixing them. Testers and developers can pair up, contribute to code, run tests pre-build, join discussions, ask questions, and provide rapid feedback to influence development decisions.
- Team Collaboration: This Agile methodology thrives in cross-functional teams with extensive collaboration and a broad range of skills. Testers are involved in development and developers in testing, resulting in a product built with testability in mind.
Employ Formal Technical Reviews
Formal Technical Reviews (FTRs) can play a crucial role in software development by detecting logical and functional errors in early stages. These are structured group meetings where participants with defined roles ensure the software meets predefined standards and requirements.
When Should FTR be Done?
Ideally, an FTR should be conducted when the product has reached a certain level of maturity, but this may vary depending on the type of review.
Roles in FTR:
A typical FTR involves a team of engineers who perform specific roles — presenters, reviewers, or recorders.
FTR Report:
At the end of the FTR meeting, a review report is prepared, answering the following questions::
- What was reviewed?
- Who reviewed it?
- What findings were made?
- What decisions were taken?
Types of FTR:
- Formal Review: The product author gives a presentation to introduce the product to the rest of the reviewers. The aim is to get the product accepted, suggest modifications if any, and discuss timelines.
- Walkthrough: The reviewers examine the product’s source code, design, and documented requirements to find bugs. The code author is often present to answer any questions.
- Inspection: While formal reviews and walkthroughs focus on bug detection, inspections are conducted to either expand initial standards or verify if previous bugs have been resolved.
Effective bugs report
A stellar bug report can cut through the confusion, spotlight the problem, and set you on the path to resolution.
How do you draft a top-notch bug report? Here’s your guide:
- Be solution-oriented — don’t just outline the problem, propose a solution. Guide the developer through the ideal feature behavior.
- Replicate before reporting, making sure the bug is a persistent troublemaker. Lay out a simple, step-by-step guide to recreating it. Even occasional glitches are worth noting.
- Be crystal clear about what you see and what you expect to see. Put it all down — the good, the bad, and the glitchy. Remember, one problem per report keeps confusion at bay.
- Screenshot it — a picture paints a thousand words, especially for bugs. Highlight the issue to give engineers a visual guide.
- Summarize smartly, capturing the essence of the bug — it will make identifying and searching for bugs as easy as ABC.

Summing up
In the intricate world of software development, a robust and well-integrated QA process stands as a beacon, safeguarding the product’s integrity and end-user satisfaction. We’ve journeyed through the disastrous tales of neglected QA, emphasizing the dire need to prioritize software quality at every phase. Understanding and differentiating between the three crucial areas of software quality — assurance, control, and testing — form the bedrock of any successful digital product. Leveraging methodologies such as extreme programming, early and often testing with a shift-left approach, and the meticulous implementation of Formal Technical Reviews demonstrates the depth and breadth of considerations required. The potency of a clear bug report and the value of test management tools further augment the QA process, bridging gaps between expectations and deliverables. In essence, to transcend the challenges of today’s fast-paced software development landscape, it is paramount to embed a rigorous QA methodology from the project’s conception to its culmination. Remember, great products aren’t just born; they are thoroughly tested, refined, and perfected.
