A couple of years ago, my first few days on a new web performance project were always slow going. So many false starts, tedious workflows, and a complete lack of efficiency really made it difficult for me to find momentum. All through no fault of the client or the project, but through huge flaws in my own approach. In a bid to address this, I introduced a new tool into my arsenal so that I could hit the ground running much faster, and get answers to my clients much sooner.

When I first stumbled on the idea of skeleton screens, thanks to Luke Wroblewski talking about them back in 2013 , I latched onto them pretty quickly. I have never been a fan of progress bars and spinners, and skeleton screens seemed like a smart step in the right direction. For those unfamiliar, a skeleton screen is a method of displaying the outline (skeleton) of the content to come, typically using gray boxes and lines instead of a progress bar while content is loading.

QA pros are no longer solely responsible for testing and finding defects, but now must take pains to ensure that the rest of the software delivery team instills quality in their work, according to this year's World Quality Report 2020-21 (WQR).

Remember when test automation was being peddled as a silver bullet for testing bugbears? Of course, those vendors really meant test execution automation. Automating test execution was going to increase coverage, minimize testing time, and overall reduce the amount of money being spent on testing. It would even butter your toast in the morning. Well, those days are long gone.

This was no small task given the mismatch between a fine granularity of rules on the one hand and a coarse granularity of test cases on the other.
