“In just a year, one test team reduced its test cycle by more than 50 percent. It took analysis, planning, and effort—first they looked into how they spent their time, and then they questioned whether they could reduce time in any of those areas. Once they knew where they could be more efficient, they could start tackling their blockers. Here's how you can, too.

Loops of exploration, experimentation, studying, modeling, and learning are the essence of testing, not an add-on to it. The intersection of activity and models (such as the Heuristic Test Strategy Model) help us to perform testing while continuously developing, refining, and reviewing it. Testing is much more than writing a bunch of automated checks to confirm that the product can do something; it’s an ongoing investigation in which we continuously develop our understanding of the product.
