Verification and Validation is not only about tools, methods and processes. Crucial is also people and how they think.
The "Six Thinking Hats" is a thinking and problem solving tool developed by Edward de Bono [1]. Julian Harty at Google has adapted the hats to testing and presents the "Six Testing Hats" [2]. Julian has successfully applied this both in reviews, for checklists and in creating acceptance tests. They can be a good way to structure the thinking involved in V&V.
In general there is a lack of research and results on how the thinking, personality and psychology of testers, affect the testing. However, there is a growing community of people who want to acknowledge and investigate this mental side of software development more [3].
How is your V&V thinking doing today?

Reviews and inspections are ways to find problems and increase quality of software and development artefacts. In fact, they are among the most effective methods known. Many practitioners use them. However, many do not, do them partly (without preparation) or do not use them continuously. With shorter release cycles these methods are often avoided altogether. |
