Generally, the tool of comparison between performances of each stage in the life of a project, is the percentage of project progress, which in most cases is only determined as One-Dimensional with referring to one factor (Physical / Time or Cost). In many projects in developing countries, there are controversies on accuracy and the way of analyzing progress. Identifying weakness points of One-Dimensional look on project and determining a reliable and engineering approach for multi-dimensional decoding information receivable from reports is of great importance in project management. This can be a tool to help identification of hidden diseases and problems before appearing irreversible symptoms that are usually delay or increased costs of execution. The method used in this paper is defining and developing a hypothetical project (based on several real project situations and restrictions) as an example and investigates distinct scenarios and numerical comparison of them, and finally, by analyzing different scenarios, the possibility or impossibility of predicting the occurrence is examined through the evidence of One-dimensional method.
