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"〔Dettmer, H,W. 1999. The conflict resolution diagram: Creating win-win solutions, Quality Progress,32(3):41〕 - 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. Harnessing resistance: using the theory of constraints to assist change management. Journal of European Industrial Training. 25/2/3/4 () 168±191〕 () ← () () / ↑ / \ () conflict OR () () \ ↓ ↑ ↑ () ← () () ↔ () The boxes represent two opposing ''wants'' that represent the conflict (D, D’), the ''needs'' that each want is trying to satisfy (B, C), and a common ''objective'' or goal (A) that both needs are trying to fulfil. The lines or arrows connecting the nodes represent the rationale or causal assumptions that are used to link the nodes. When communicating the cloud, the arrows should be read as “in order to” or “because” or “so that”. For example: ''“In order to achieve A we require B because there is no way we can have A without B.”'' Or: ''“There is no way we can have D and have D’ ''(read as "D-prime")'' at the same time.”'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Evaporating Cloud」の詳細全文を読む スポンサード リンク
