Test Managers in Agile – Creating the Right Culture for Your SQA Team

I was once asked at a testing summit, “How do you manage a QA team using scrum?” After some consideration, I realized it would make a good article, so here I am. Understand that the idea behind developing software in a scrum environment is for development teams to self-organize.

A Reconsideration of Software Testing Metrics

There is just one area where each member of the software testing community has a distinct point of view! Metrics! This contentious issue sparks intense disputes, and most conversations finish with no definitive conclusion. It covers a wide range of topics: How can testing efforts be measured? What is the most effective technique to assess effectiveness? Which of the many components should be quantified? How can we measure the quality of our testing performance, among other things?
