Developing success criteria model, quantitative evaluation method, and process framework for building projects
Abstract
The construction industry faces challenges in evaluating success due to inconsistent methods and a lack of uniformity. Traditional evaluation methods often result in subjective and biased results. Professionals, stakeholders, and researchers disagree on assessment techniques. The paper aims to identify stakeholder-responsive evaluation criteria, establish an evaluation criteria model, develop a quantitative evaluation algorithm, and provide an evaluation process framework. This method and framework fill traditional evaluation gaps, reduce subjectivity and bias, enhance accuracy, simplify evaluation, and are suitable for project evaluation. Data was gathered from experts and project stakeholders through focus group discussions, interviews, archive documents, and site observations. First, identify criteria and subcriteria and develop a criteria-relation model that achieves fitness indices and passes validity and reliability tests. Next, quantitative evaluation weighted coefficients were determined, and an algorithm was developed. A quantitative evaluation of a case study revealed that project seven has very high success; projects three, six, eight, and nine have high success; project two has medium success; projects one, four, and five have low success; and there is no project with a very low success. Projects achieved average success rates of 86.42, 79.6, 66.5, 71.17, 83.63, 81.27, and 89.14% in quality, cost, time, safety, impact, satisfaction, and lesson learning, respectively. This study is novel and original due to its criteria structural equation model, quantitative evaluation algorithm with inclusive criteria index, and unique evaluation processes framework. This enhances evaluation science, providing new insights for stakeholders, professionals, academics, and policymakers, and enhancing stakeholder communication in future project success evaluations.
