Prof Simon French recognizes "the value of the Cynefin framework in categorising decision contexts and identifying how to address many uncertainties in an analysis" and as such believes it builds on seminal works such as Russell L. Ackoff's Scientific Method: optimizing applied research decisions (1962), C. West Churchman's Inquiring Systems (1967), Rittel and Webber's Dilemmas in a General Theory of Planning (1973), Douglas John White's Decision Methodology (1975), John Tukey's Exploratory data analysis (1977), Mike Pidd's Tools for Thinking: Modelling in Management Science (1996), and Ritchey's General Morphological Analysis (1998).[38]
