Prerequisite Tree
The thinking processes in Eliyahu M. Goldratt's theory of constraints are the five methods to enable the focused improvement of any cognitive system (especially business systems). Purpose The purpose of the thinking processes is to help answer questions essential to achieving focused improvement: # ''What to change?'' # ''What to change it into?'' # ''How to cause the change?'' Sometimes two other questions are considered as well: ''Why change?'' and: ''How to maintain the process of ongoing improvement (POOGI)?'' A more thorough rationale is presented in ''What is this thing called theory of constraints and how should it be implemented''. A more thorough work, mapping the use and evolution of the Thinking Processes, was conducted by Mabin et al. Processes The primary thinking processes, as codified by Goldratt and others: * Current reality tree (CRT, similar to the current state map used by many organizations) — evaluates the network of cause-effect relations be ...

Eliyahu M
Eliahu or Eliyahu is a masculine Hebrew language, Hebrew given name and surname of biblical origin. It means "My El (deity), God is Yahweh" and derives from the prophet Elijah who, according to the Bible, lived during the reign of King Ahab (9th century BCE).

Focused Improvement
Focused improvement in the theory of constraints is an ensemble of activities aimed at elevating the performance of any system, especially a business system, with respect to its goal by eliminating its constraints one by one and by ''not'' working on non-constraints. Focused improvement can also be defined in simpler terms as a process that identifies the systems problems and then modifies the whole system in order to find the most cost effective, time saving and least disruptive solutions in order to optimize the system. "Focused Improvement is the process of applying systematic problem solving methods to manufacturing. The process relies on aligning the correct method to the correct scenario". Development and Apparition Focused improvement was developed as a working part of the Theory of Constraints management philosophy by Eliyahu M. Goldratt in his 1984 book titled ''The Goal ''The Goal'' is a management-oriented novel by Eliyahu M. Goldratt, a business consultant know ...

System
A system is a group of Interaction, interacting or interrelated elements that act according to a set of rules to form a unified whole. A system, surrounded and influenced by its environment (systems), environment, is described by its boundaries, structure and purpose and expressed in its functioning. Systems are the subjects of study of systems theory and other systems sciences. Systems have several common properties and characteristics, including structure, function(s), behavior and interconnectivity. Etymology The term ''system'' comes from the Latin word ''systēma'', in turn from Greek language, Greek ''systēma'': "whole concept made of several parts or members, system", literary "composition"."σύστημα" Henry George Liddell, Robert Scott, ''A Greek–English Lexicon'', on Per ...

Business
Business is the practice of making one's living or making money by producing or Trade, buying and selling Product (business), products (such as goods and Service (economics), services). It is also "any activity or enterprise entered into for profit." Having a business name does not separate the business entity from the owner, which means that the owner of the business is responsible and liable for debts incurred by the business. If the business acquires debts, the creditors can go after the owner's personal possessions. A business structure does not allow for corporate tax rates. The proprietor is personally taxed on all income from the business. The term is also often used colloquially (but not by lawyers or by public officials) to refer to a company, such as a corporation or cooperative. Corporations, in contrast with Sole proprietorship, sole proprietors and partnerships, are a separate legal entity and provide limited liability for their owners/members, as well as being su ...

Current Reality Tree (theory Of Constraints)
One of the thinking processes in the theory of constraints, a current reality tree (CRT) is a tool to analyze many systems or organizational problems at once. By identifying root causes common to most or all of the problems, a CRT can greatly aid focused improvement of the system. A current reality tree is a directed graph. Simplified explanation A CRT is a focusing procedure formulated by Eliyahu Goldratt, developer of the theory of constraints. This process is intended to help leaders gain understanding of cause and effect in a situation they want to improve. It treats multiple problems in a system as symptoms arising from one or a few ultimate root causes or systemic core problems. It describes, in a visual (cause-and-effect network) diagram, the main perceived symptoms (along with secondary or hidden ones that lead up to the perceived symptoms) of a problem scenario and ultimately the apparent root causes or core conflict. The benefit of building a CRT is that it identifies the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evaporating Cloud
The Evaporating Cloud is one of the six Thinking Processes in the Theory of Constraints. The Evaporating Cloud (EC) - also referred to in the literature as "the cloud", or as a "conflict resolution diagram" - is a logical diagram representing a problem that has no obvious satisfactory solution.Fedurko, Jelena. Behind the cloud: Enhancing logical thinking. TOC Strategic Solutions Ltd (2011) Overview The most commonly used of the TOC tools, the EC was designed to address conflict or dilemma situations (trade-off situations where there is no acceptable compromise) by diagramming the logic behind the conflict and methodically examining the assumptions behind the logic. The EC has a set format with five boxes, labelled A, B, C, D, D’, that are usually laid out as follows:Victoria J. Mabin, Steve Forgeson and Lawrence Green.

PDCA
PDCA (plan–do–check–act or plan–do–check–adjust) is an iterative design and management method used in business for the control and continual improvement of processes and products. It is also known as the Shewhart cycle, or the control circle/cycle. Another version of this PDCA cycle is OPDCA. The added "O" stands for ''observation'' or as some versions say: "Observe the current condition." This emphasis on observation and current condition has currency with the literature on lean manufacturing and the Toyota Production System. The PDCA cycle, with Ishikawa's changes, can be traced back to S. Mizuno of the Tokyo Institute of Technology in 1959. PDCA is often confused with PDSA (Plan-Do-Study-Act). Dr. W. Edwards Deming emphasized the PDSA Cycle, not the PDCA Cycle, with a third step emphasis on Study (S), not Check (C). Dr. Deming found that the focus on Check is more about the implementation of a change, with success or failure. His focus was on predicting the results ...
