“…Uncertainties that are impossible to foresee mean that risks will always be present. This risk can result in losses that must be borne by the company [5] [6]. Output risk is an uncertainty that directly impacts a firm's output in terms of quantity and quality or results in changes in planned production output.…”

This research was conducted in a company that operates in the printing or graphics sector. The concept of quality control is the most critical part because newspapers or printed media are products with the fastest production process. PT carries out the quality control process. PT XYZ to lower the failed results on the paper. Quality control measurements use the P chart method. Results of quality control measurements at PT. XYZ is outside the control limits, and that is not normal, so corrective action is needed, especially the number of failed newspapers. On average, newspapers failed from January to May, reaching 8.24% of the total newspapers produced. Events that cause failure in newspapers are analyzed through risk management. Risk management measurements use the Risk Breakdown Structure (RBS) and Fault Tree Analysis (FTA) methods. Risk management results show that five risks cause newspaper failure, namely scattered ink, slanted fonts, blurred images, dirty images, and thick fonts.

The research aimed to establish a quantitative model to predict the occurrence of five types of design defects: unsafe design, incompatible design, inefficient design, design ambiguity, and design delays. It also examined the contractor's liability for design to determine who is ultimately responsible for design defects disputes between the employer and contractor. The study employed a descriptive methodology to identify fifteen potential influencing factors on design defects. Data were collected from 42 construction projects and tested using Design of Experiments (DOE). Out of these fifteen factors, only five—design schedule, design firm experience, stakeholders’ involvement, project delivery system, and information accuracy—had a significant impact on design defects. These factors were used in the development of a new model to predict the occurrence of design defects. The model was validated using data that was held separate from the model development process for validation purposes. The calculated Mean Absolute Percentage of Error (MAPE) for the new model is 19%, which is considered a "good" prediction accuracy. The research achieved three significant milestones: 1) It identified the ultimate responsibility for the consequences of design defects in construction projects across different jurisdictions. This information can be used to resolve potential disputes between employers, designers, and contractors’ organizations. 2) It provided guidelines on how to minimize design defects in construction projects, thereby mitigating the consequences of such defects. 3) It developed a new model to predict the occurrence of design defects in construction projects. This model aids decision-makers in responsible organizations during the process of predicting the appropriate reserve to be added to the project schedule and budget. Consequently, it helps mitigate the risk of design defect-related delays and cost overruns. Doi: 10.28991/CEJ-SP2023-09-017 Full Text: PDF
