Variables Impacting Design Effectiveness Key to Project Qualityby A. Fattah Chalabi, Worcester Polytechnic Inst, United States,
Abstract: This paper reports on two-year research at Worcester Polytechnic Institute, which was supported by the Construction Research Institute (CII). Over forty (40) input variables to design were identified, analyzed and ranked by the researchers to select the most important (ten) variables. An acceptable definition of design effectiveness is developed by consensus among the industry. Seven design output criteria, for measuring design effectiveness, were selected from a list of 25 identified. The design input variables were then correlated with the design effectiveness measurement criteria, and the impact of the input variables on the outcome of design were weighted. Recommendation for modifying any negative impacts from the input variables on design effectiveness were then offered for each variable, and guidelines to assist current efforts by the industry to improve project quality by increasing design effectiveness were developed.
