With the term Cynefin Dave Snowden describes how to projects can be understood as being either or several of four domains, and what specifies their individual challenges:
Linear causal connections are obvious and easily understandable, e.g. dirty hands.
Categorize
Best Practices
Linear causal connections are not obvious but easily understandable, e.g. machine engineering.
Analyze
Good Practices
Linear causal connections cannot be understood through analysis alone, but through study, e.g science. This is the domain of Agile processes.
Study
Emergent Practices
Linear causal connection do not exist. They can maximally be expressed in probabilities, e.g. weather. These are non-deterministic.
Act
Novel Practices
The danger is categorizing wrong and thus finding bad solutions due to bad practice.
