Timing, cost, and quality are the key elements in the construction project. (We can call it ¡§elements triangle¡¨) Whenever one of the elements is being changed, such as the project progress delay, the cost surpass the budget or the quality flaw excessively many and so on, usually the solution is to modify the problem part, but we miss the ¡§System Dynamics¡¨ of the construction project. The elements are involved to each other. Therefore, when we adjust the deviation part of the element; actually the adjustment also involves changes of the other elements or even the whole construction project, but still not solves the problem. It causes the recycle of the deviation occurs continually, but not the solution. According to the complex system dynamics, we found the best solution form the research of several construction cases with its management strategy and identities: 1. Adjust the deviation according to the person who is in charge of the project is better than just adjust the problem part of the elements. 2. Improve the satisfaction to the person who is in charge of the project and the cooperators for obtaining a better effect. 3. Applies the case occurs from the dynamic simulation method analysis practical field will enhanced the result of the inspection improvement plan, but also effected to the deviation analysis.
