Lean Construction Ireland Annual Book of Cases 2021 28 ISO 9001:2015 Quality Management Standard. Each audit is scored to evaluate the compliance criteria, and these scores provide a mechanism to assess the compliance of our system through the construction stage of each project.The results and findings from each audit provide an opportunity to improve our quality management system for both internal and external customers.The findings and results of each audit are assessed and then calculated and placed within the following compliance ranges: • Compliant: 95-100 • Mainly Compliant: 90-94 • Non-Compliant: 0-89 Each audit report is then circulated to the relevant project teams for action as required.Through our continuous improvement programme, and flexible approach with adopting our quality auditing processes, we have successfully gathered valuable information to allow our systems to be improved. We recently carried out an A3 Lean project to assess our overall findings betweenAug 2018 and March 2021, and our average score in 2018-2019 was 93.68, which was within our mainly compliant range. In 2019-2020, we improved our average score to 94.25. It should be noted that the project stages change over time and therefore the items being audited may vary from project to project depending on the stage of the project. DBL sets a high standard when it comes to quality control and quality management, and thus projects that reach the mainly compliant range are achieving a high result.That said, there is always room for improvement in any process, and thus our commitment to continuous improvement is integral to who we are. Figure 1 outlines our assessment of the current conditions and theVoice of the Process during an assessment from Sep 2019-Sep 2020, plus the average scores noted in Aug 2018-Aug 2019. Figure 1. Outcome of Current State throughout Sep 2019-Sep 2020 Opportunities for improvement were identified though our biweekly quality audits across nine live construction projects at the time of auditing. Key items selected for improving included site inspections, site diary records, two peg test recording, first in place/ benchmarking recording, and recording of SR21 granular fill. Once we assessed the opportunities for improvement, we were able to take a deeper dive and outline our goals and targets to make the improvements happen. Goals/Targets Our overall goal was to increase our audit results to achieve a score of 95 and above by April 2021 following a deep dive into available opportunities, and it can be seen that a number of our projects had already achieved 95 and above at our baseline stage. However, some projects required more focus to bring our average scores across the nine projects into the compliant range.The frequency of the audits was also assessed, and the goal was set to ensure that audits were consistently carried out every 2 weeks on each project, and our target was to achieve 95 and above.Table 1 outlines our baseline scores versus our intended goals and targets to be reached. Table 1. BaselineVersusTarget Having identified the key items, we were then able to analyse root causes and determine where we needed to focus in order to make improvements. Our quality management team assessed our audit reports in detail and analysed why we were not reaching 95 and above as standard across our projects.Our assessment can be seen in the Cause and Effect Diagram (Figure 2) and Failure Mode Effects Analysis (FMEA) chart (Figure 3).
