I originally envisaged these two articles as a single piece, but I broke it in two when the first one became too long.
They discuss the insights the Cynefin Framework offers into ISO 29119. The first article gives a quick overview of Cynefin and discusses its relevance to testing and auditing.
The second article contrasts ISO 29119’s confusion over “best practice” with the clearer and more relevant perspective offered by Cynefin.
