Why Do Defects Escape?

What happens when defects go unnoticed until it is too late? Mayank provides an insightful view of the true cost of not providing enough test coverage during a software development lifecycle. He also suggests some techniques to ensure that defects are identified and mitigated early.

So, You've Got a Problem: Crafting Remarks and Abstracts for Defect Reports

Software defect reports are among the most important deliverables to come out of software testing. They are as important as the test plan and will have more impact on the quality of the product than most other deliverables from the software test team. It's worth the effort to learn how to write an effective defect report that conveys the proper message and simplifies the process for everyone.

Stop The Insanity! Using Root Cause Analysis to Avoid Repeating Your Mistakes

We've all heard Einstein's definition of insanity, and it definitely holds true in software development. We "are" going to make mistakes in product development, but root-cause analysis can help us understand those mistakes and be proactive in not repeating them.

Detection Theory Applied to Finding and Fixing Defects
Slideshow

Detection theory says: When trying to detect a certain event, a person can correctly report that it happened, miss it, report a false alarm, or correctly report that nothing happened. Under conditions of uncertainty, the decision to report an event is strongly influenced by how likely it...

What Do Defects Really Cost? Much More Than You Think
Slideshow

As software increasingly becomes the face of the business, defects can lead to embarrassment, financial loss, and even business failure. Nevertheless, in response to today's demand for speed and “continuous everything,” the software delivery conveyer belt keeps moving faster and faster...

Orthogonal Defect Classification: An Agile Test/QA Primer
Slideshow

Can defect root cause analysis be made agile? Can we transform a multi-hour task from the classical world of software engineering into one that takes minutes and yields greater insights? Learn how Orthogonal Defect Classification (ODC) extracts semantics from defects and turns them into insights on the development process using analytics. After a quick overview of ODC, Ram Chillarege presents a case study to illustrate the method using real-world data on an agile project. They used ODC Triggers to measure test effectiveness at the end of every sprint to evaluate the effectiveness of testing compared to earlier sprints. This ODC process takes just minutes and brings its insight into the realm of the agile development practices. Put a powerful analytical technique in your agile toolbox to increase the velocity of your agile project and find new ways to reduce defects while measuring the quality of testing.

Better Than a Root Canal: Root Cause Analysis of Defects

The quality problems many companies face after releasing a new product can be as painful as a root canal. One way to avoid this pain is timely root cause analysis (RCA) during development. Proper RCA and resulting improvements prevent product failures, eliminate associated rework, and reduce the pain of initial product releases. Based on empirical research conducted on today's RCA practices in the industry, Jan van Moll explains why many companies fail to do effective root cause analysis in practice. Presenting astonishing RCA data from projects, Jan shares specific examples of successes and failures with RCA. He points out the common pitfalls of defect analysis and demonstrates how to work toward problem solutions in a pragmatic and practical manner. Learn the critical success factors of RCA derived from industry experience to improve your practices and produce better products.
