The Logical Thinking Process

Bill Dettmer is a thinking process pioneer. He's taken the methodology to new levels. His training of Six Sigma belts at Seagate Technologies has fundamentally changed the way problems are analyzed and solutions are developed. We now see Six Sigma in ways we'd never have thought of without his contributions. Our use of the thinking process is now strategic, rather than just tactical. The Dettmer approach to the thinking process is built into Seagate Six Sigma training.

Getting strategy right isn't a matter of luck. Bill Dettmer showed us a way to apply the logical thinking process to develop a living strategy.

The logical thinking process (TP), developed by Dr. Eliyahu M. Goldratt, attacks the problems of organizational improvement from a system, rather than a process perspective. The most difficult problems any organization experiences stem from policy constraints: the rules, measures, or practices imposed on an organization— either from within or from without. Policy constraints limit the organization’s ability to perform to its maximum. By identifying and breaking such policy constraints, an organization usually realizes immediate and dramatic gains in performance.

A Five-Part Method. The Thinking Process is a five-part method for enabling anyone in any kind of organization to determine:

  • What to change?
  • What to change to?
  • How to execute the change?

Composed of five logical trees, the Thinking Process provides a structured way to “navigate” complex change.

WHAT’S THE PROBLEM?

The Current Reality Tree reveals the root causes of the undesirable effects in any system---the constraint preventing improved performance.

WHAT DO WE DO ABOUT IT?

The "Evaporating Cloud" (a conflict resolution diagram) identifies and resolves overt and hidden conflict. Breaks chronic conflict perpetuating Root Causes of undesirable effects. Helps create new solutions.

The Future Reality Tree verifies validity of proposed solutions before resources are invested in them. Identifies possible adverse side-effects of the proposed solution and ways to prevent them.

HOW DO WE MAKE IT HAPPEN?

The Prerequisite Tree uncovers obstacles to implementation of solutions. Helps develop ways around the obstacles and time-sequences the actions required to overcome them.

The Transition Tree builds a step-by-step implementation plan for each facet of the change and provides the rationale for persuading people to follow it.

WHAT YOU WILL BE ABLE TO DO AFTER ATTENDING THIS COURSE

  • Successfully identify the causes of personal and professional problems of any complexity using logical, verifiable cause-and-effect
  • Identify and resolve both day-to-day and chronic conflicts that hinder you or your organization from achieving your goals
  • Evaluate the potential for success before initiating change, either in your life or your organization
  • Uncover the pitfalls that could result from any change you might contemplate, and determine what you should do to "navigate" around them
  • Identify the "roadblocks" to successful change and the ways to overcome them (and in what order)
  • Lay out a detailed implementation plan for change and persuade others to help with it
  • Improve the odds of successful change before you even begin taking action
  • Quickly identify questionable or ill-considered proposals from others

 

WHO SHOULD ATTEND?

  • Senior executives with strategic or tactical management responsibilities
  • Internal or external consultants responsible for complex problem-solving
  • Project managers faced with a rapidly changing environment
  • Managers with responsibility for Total Quality or Continuous Improvement within their organizations

INSTRUCTOR. H. William Dettmer, formerly an adjunct faculty member, University of Southern California Institute of Safety and Systems Management. Author of Goldratt’s Theory of Constraints: A Systems Approach to Continuous Improvement and Breaking the Constraints to World-Class Performance.

The logical Thinking Process helped both my company and our clients set and accomplish strategic goals in a very straightforward fashion. Bill's books are the best and clearest on the subject of TOC; taking his courses helped to cement the concepts and apply them immediately.  The course activities were like participating in a well-facilitated offsite planning session.

In 2004, The TOC Centre of Australia (TOCCA) brought Bill Dettmer to Australia for help in developing a strategy for the company using the Thinking Process methods in the framework developed by Bill in his book Strategic Navigation. In March 2004, Bill spent 5 days with all of our consultants and managed to quickly tap into the locked up knowledge stored in the heads and hearts of the people who make TOCCA tick!

    Bill’s excellent facilitation and profound knowledge of business allowed us to quickly start dealing with the major issues facing the company and agree on the few root causes of our under-performance relative to the goals we had set ourselves. We developed a detailed future reality tree, logically stepping through all things necessary and sufficient to delivering on sustainable profitable growth. This tree is printed and mounted on the wall of our office, a constant source and inspiration for what we have to do to achieve our goals.

    What was particularly gratifying about Bill’s facilitation was that at the same time as we were developing the logic of our current and future reality we were also learning from a true master about the use and real power of the Thinking Process tools of the Theory of Constraints. The icing on the cake must be Bill’s friendly attitude and clear love of his subject—all resulting in a genuine commitment from all the participants in the exercise.
