IT Workforce Development

The recent CrowdStrike update causing widespread outages is deeply troubling. With over 25 years of experience leading critical systems releases, I understand the challenges, but outages of this magnitude demand answers. Even the most talented programmers encounter defects, some frustratingly elusive. This is why robust quality assurance (QA) processes are an absolute necessity, especially for software entrusted with safeguarding our systems. Throughout my career, I've championed a multi-layered QA approach that acts as a safety net, scrutinizing software from every angle. This includes: ➡️ Code Reviews: Regular peer reviews by fellow developers identify potential issues early. ➡️ Testing Pyramid: A range of tests, from focused unit tests to comprehensive system and integration tests mimicking real-world use, are employed. ➡️ Stress and Capacity Testing: Pushing software beyond its normal limits helps expose vulnerabilities that might otherwise remain hidden. ➡️ Soak Testing: Simulating extended periods of real-world use uncovers bugs that only manifest under prolonged load. By implementing these techniques, QA teams significantly increase the likelihood of catching critical defects before they impact users. CrowdStrike owes its customers transparency. A thorough investigation and a clear explanation of how such a disruptive bug bypassed safeguards are crucial. Understanding this will help prevent similar incidents in the future. This outage serves as a stark reminder for both software providers and buyers. Providers must prioritize rigorous QA processes. But buyers also have a role to play. I urge all software buyers to carefully audit their vendors' QA practices. Don't settle for anything less than a robust and multi-layered approach. Our security depends on it. Our economy and indeed our life today, depends on software. We cannot allow this type of outage to disrupt us in the future! By prioritizing rigorous testing and demanding transparency, we can work together to ensure the software we rely on remains a source of security, not disruption. _______________ ➡️ About Me: I'm Talila Millman a fractional CTO and a management advisor, keynote speaker, and executive coach.

🚀 QA vs QC vs QE vs Tester: Do they really mean the same thing? In the world of software development, we often hear these terms as if they were interchangeable... but they are not. Each role adds value from a different perspective within quality. Here is a brief and practical 👇 explanation 🔵 QA – Quality Assurance ➡️ Prevents defects ➡️ Define processes, standards and best practices ➡️ Focuses on how software is built ➡️ More strategic and preventive work Think of QA as, "Let's get it right from the start." 🟣 QC – Quality Control ➡️ Detect defects ➡️ Review the finished product or in specific phases ➡️ Focuses on what is delivered ➡️ More reactive work, evaluating the final result QC is: "Let's validate that what was done meets expectations." 🟢 QE – Quality Engineering ➡️ Unites quality + engineering ➡️ Automation, CI/CD, Quality Metrics, Tools ➡️ Ensures quality through technology and engineering ➡️ Key role in DevOps/Agile teams QE is, "Let's make quality flow into the pipeline." 🟡 Tester – Test Analyst/Engineer ➡️ Run manual or automated tests ➡️ Understand requirements, design test cases, report bugs ➡️ Ensures software works as expected ➡️ Direct focus on product behavior Tester is: "Let's prove that everything works... and find what we don't." 💬 Final Thoughts Quality is not the responsibility of a single person, but these roles help make it a natural part of the development cycle. Understanding the differences allows us to collaborate better and build more reliable software.

💻 Developer: “It works perfectly on my computer.” 🧪 Tester: “That’s good. But the customer isn’t using your computer.” And that right there captures the essence of the relationship between Development and Quality Assurance. Coding proves functionality in a controlled environment. Quality Assurance validates functionality in the real world. A developer’s environment is usually optimized: • Stable internet • Clean database • Updated browser • Ideal configurations • Familiar workflows But production is different. Real users operate on: • Slow or unstable networks • Older devices and browsers • Unexpected screen resolutions • Incomplete or invalid inputs • Concurrent sessions • Unpredictable behavior QA doesn’t just test what should happen. QA evaluates what could happen. It’s not about questioning the developer’s capability. It’s about validating system resilience. A feature may work technically — but: • Does it fail gracefully? • Does it handle incorrect data securely? • Does it scale under load? • Does it maintain performance consistency? • Does it preserve user experience across devices? That is the difference between functional code and reliable software. When testers ask difficult questions, they are not creating friction — they are reducing risk. They are thinking ahead: • What breaks under pressure? • What happens outside the happy path? • What assumptions are untested? • What edge case might impact thousands of users? Users never see internal conversations. They only experience the outcome. And users don’t care where it worked. They care where it failed. Professional software teams understand that Development builds the product — but QA protects the product in reality. Behind every stable release is a tester who: • Challenged assumptions • Explored edge cases • Simulated real-world scenarios • Validated beyond the obvious That discipline is not obstruction. It is responsibility. Respect the build. Respect the validation. Respect the process that turns code into quality. #QALife #SoftwareTesting #DevVsQA #QualityAssurance #BugHunting #SoftwareDevelopment #ITLife #ProductQuality

14 Software Testing Approaches Every QA Should Know! As a QA Tester, my role is not just about finding bugs — it’s about ensuring quality, reliability, performance, and user satisfaction. The infographic below summarizes 14 different software testing approaches that we use in real-world projects. Let me break them down with simple real-time examples 👇 🔹 Unit Testing – Testing small, isolated pieces of code. 💡 Example: Checking if a “discount calculation function” returns the correct value. 🔹 Integration Testing – Ensuring modules interact properly. 💡 Example: After integrating the login API with the frontend, test if login tokens are passed correctly. 🔹 Functional Testing – Verifying software works as per requirements. 💡 Example: Testing if the “Add to Cart” button correctly adds items in an e-commerce app. 🔹 Regression Testing – Making sure new changes don’t break old features. 💡 Example: After updating the payment gateway, test checkout flow to ensure previous payment methods still work. 🔹 Performance Testing – Measuring speed, scalability, and responsiveness. 💡 Example: Checking if a food delivery app can handle 10,000 users ordering at once. 🔹 Security Testing – Identifying vulnerabilities. 💡 Example: Ensuring user passwords are encrypted and SQL injection attacks are blocked. 🔹 Usability Testing – Checking user-friendliness. 💡 Example: Testing if elderly users can easily navigate a healthcare app. 🔹 Smoke Testing – Quick check to validate basic functionality. 💡 Example: Right after deployment, ensuring “Login → Dashboard → Logout” works fine. 🔹 Sanity Testing – Focused verification of recent fixes/features. 💡 Example: If a bug was fixed for incorrect price calculation, check only that specific feature. 🔹 Acceptance Testing – Making sure software meets business/user expectations. 💡 Example: Client verifying a banking app to ensure fund transfer flow works end-to-end. 🔹 Exploratory Testing – Ad-hoc testing without predefined test cases. 💡 Example: Randomly trying invalid inputs in a sign-up form to see how the system reacts. 🔹 Alpha Testing – Internal team testing before public release. 💡 Example: QA team using a new ride-hailing app internally before launching it. 🔹 Beta Testing – External user testing in a real environment. 💡 Example: Early users testing WhatsApp beta version before global rollout. 🔹 Compatibility Testing – Ensuring the app works across browsers/devices. 💡 Example: Verifying an online store works on Chrome, Safari, Android, and iOS. Each of these testing methods is crucial depending on where we are in the SDLC (Software Development Life Cycle). 👉 Which of these do you use the most in your projects? #SoftwareTesting #QATesting #QualityAssurance #TestAutomation #ManualTesting #PerformanceTesting #SecurityTesting #SDLC #Tech #SoftwareQuality #AgileTesting #QATips #TestingLife
