The Trouble with models - specifically the agile testing quadrants

We all use models, or heuristics in our testing, but we also use them in everyday life. Once a model is put out there for other people to use, it becomes either something useful, or in some instances a target to destroy . In Lisa Crispin’s and Janet Gregory’s Agile Testing book, they shared their version of the agile testing quadrants (2008) based on Brian Marick’s agile testing matrix (2003) which they had used extensively.

In the past year, several people have adapted the quadrants, including Janet and Lisa in More Agile Testing. That is good. However, because models are inherently flawed, there is a tremendous amount of misinterpretation of the model. That is bad because it leads to incorrect conclusions.

Janet will talk about the some of these issues that arise, and try to correct misunderstandings, but will also share some of the great alternatives people have suggested.
