History & Acknowledgements
Isabel Briggs Myers outlined a four step methodology for applying the insights of C. G. Jung's model of personality type to problem solving in both Introduction to Type and Gifts Differing. Gordon Lawrence discussed it further in People Types and Tiger Stripes; and in fact most type professionals today know the four step model by the name he gave to it: "zig-zag" analysis.
By distinguishing between the extraverted and introverted attitudes of each of the four Jungian functions, the four-part model can be further refined into eight mental processes, as detailed in Jung's Mental Processes: Building Blocks of Type (Haas and Hunziker, 2006, available at www.16types.com). The eight steps that form the core of the Integrated Problem-Solving™ training system are taken directly from this work.
The essence of the IPS system consists of using the eight step problem solving model as the framework for systematically exploring each of the eight Jungian mental processes, in an experiential exercise that focuses a real team on resolving a real issue. Many trainers have used four part problem solving exercises to teach about type. Some have probably used real-life situations in such training. It is the unique combination of these elements, along with the eight-process model of type, into a formalized training approach that is protected by trademark law under the name "Integrated Problem-Solving™;" and all associated rights are reserved.
