Theory That Makes a Difference

I've pulled together a set of links on theories that really make a difference. I've pulled the key website along with additional resources for a quick reference on the theory.

2 x 2 Thinking
Polarity Partnerships
Polarity maps provide the context for effectively addressing "unsolvable problems". They provide leaders with the insight and methodology to effectively manage the most important issues in organizations today

The Power of the 2 x 2 Matrix
The Power of the 2 x 2 Matrix is a gold mine of ideas and tools for the business problem solver. Draw from the book’s collection of 56 outstanding frameworks applied by leading business thinkers such as Michael Porter, Stephen Covey, and Igor Ansoff. These tested frameworks will help you tackle the thorniest of issues and learn how to apply 2 x 2 Thinking–the strategic orientation of the most successful and innovative problem solvers.

Cybernetics
Cybernetics and Systems Thinkers
The following is a list of the most influential theorists in the field of cybernetics and systems theory and related domains, with links to their biographies, info about their work or their home page (for those that are still alive). Their most important publications can be found in our list of basic books and papers on the domain.

Theory of Constraints
A Guide to Implementing Theory of Constraints
This website is about the Theory of Constraints – how to substantially improve an organization, any organization, by moving a group of people towards a common shared goal. It is an application-based view of Theory of Constraints. The intent is to make much of the available background and practice more readily accessible while presenting it within the broader context of other parts of the general management literature and also my personal experience. The site is divided into a number of basic topics as shown in the headings at the top of this page, and each of these basic topics will in-turn reveal a list of sub-topics once you click on the topic heading. Start at the start with the introduction. Then work your way through the topic and sub-topics on the bottom line, the core concepts needed to implement Theory of Constraints are there. Core concepts such as; the goal and necessary conditions, the 5 step focusing process, and throughput accounting. Thereafter, you will probably want to jump to your special area of interest; production, supply chain, thinking processes, strategy, project management, or healthcare.
