J Davies, VJ Marbin, JF Cox, The Theory of Constraints and Systems Dynamics: A Suitable Case for Multi-methodology
The TPs are constructed from three basic building blocks:
- cause-effect sufficiency thinking
- necessary condition thinking
- a set of rules governing the logic-in-use
.
CRT, FRT, TrT are sufficiency-based if-then logic diagrams
PRT, EC are necessity-based "in order to ..., we must ..." logic structures
