Theory of Constraints Handbook - James Cox Iii [772]
5The original early 1990s method proposed to develop a CRT used “Why?” and “Because” logic with validation, and is still in use.

8A basic set of TOC logic tools (EC, NBR, and PRT) has been taught in primary, secondary, and high schools around the world for over a decade. See Chapter 26 and www.tocforeducation.com.
1The Cloud is used in the full TP work to describe the inherent conflict reflected in the core problem that is identified in the Current Reality Tree (CRT).
2The TOCICO Dictionary (Sullivan, Reid, and Cartier, 2007, 21–22) defines the Evaporating Cloud (EC) as ” (a) necessity-based logic diagram that describes and helps resolve conflicts in a “win-win” manner. It has two primary uses, first as a structured method to facilitate the description and resolution of a conflict, and second, as an integral part of the Three-Cloud approach to creating a Core Conflict Cloud which then forms the base of a current reality tree.” (© TOCICO 2007, used by permission, all rights reserved.)
3In some instances, particularly Clouds involving more than one person, the I/we should be replaced with the part’s name if that person or function must meet that need or complete that action.
4Chronic Conflict Clouds are far more difficult to resolve. The TOCICO Dictionary (Sullivan et al., 2007, 11) defines chronic conflict as “(a) contentious situation that has continued to exist for a prolonged period of time. Opposing sides have been justifying their perspective through selective requirements and prerequisites for so long that both sides become entrenched in their own beliefs to the point that neither side can see how to break the conflict without suffering a significant loss.” (© TOCICO 2007, used by permission, all rights reserved.)
5The TOCICO Dictionary (Sullivan et. al., 2007, 27–28) defines injection with respect to the EC as: “2. A state or condition that invalidates one or more assumptions underlying the relationships between the objective and requirements, or between requirements and prerequisites, or between the two prerequisites of an Evaporating Cloud.” (© TOCICO 2007, used by permission, all rights reserved.)

8In Chapter 2 of the book It’s Not Luck by Eli Goldratt (1994), there is an example of a day-to-day conflict on a personal issue. It is a disagreement between Alex Rogo and Sharon, his teenage daughter.
9Please remember that this is a daily problem and not a detailed analysis of a deeper problem. A more comprehensive work may find that the procedure is a part of the core problem and in such a case, the solution may include a major change or even the removal of procedure.
10The TOCICO Dictionary (Sullivan et al., 2007, 50) defines an undesirable effect (UDE) as “(a) negative aspect of the current reality defined in relation to the organizational or system’s goal or its necessary conditions. UDEs are believed to be a visible symptom of a deeper, underlying root cause, core problem, or core conflict.” (© TOCICO 2007, used by permission, all rights reserved.)
11See Chapter 22 for details on constructing Mafia Offers.
12The Three-Cloud approach is also used in examining UDEs across major functions of an enterprise. However, these analyses do not fall into the category of day-to-day management and therefore are not discussed in this chapter.
