Several CEA tools are available to the analyst. Usually an analytical tool, such as the cause and effect diagram is applied for the investigation phase while a visual display tool, such as Pareto and pie charts, is used for presentation and decision support. A thorough look into these tools reveals the presence of fundamental limitations such as: (i) the particular tool is only efficient in the investigative stage but not in decision support, (ii) no qualitative and/or quantitative relationships between causes and effects can be obtained or (iii) the tool cannot accommodate multi-level CEA analyses. A new tool called the Drain-Pipe-Diagram (DPD) has been developed to overcome these limitations and enable easy decision making. The principle of the DPD derives from the working nature of a typical drainpipe network where the main collection-pipe resembles the “main effect” whereas higher-level feeding pipes resemble causes and subcauses. In addition, color coding and diametrical ratios were used to signify importance and share, respectively. The DPD was assessed against other CAE tools using a practical case study and proved to be superior to all compared CEA tools in both diagnostic and presentation abilities. Furthermore, the DPD was successfully applied to nontechnical areas including environmental applications.
