自 2007 年以来，爱尔兰的建筑产量减少了约 80%。这导致了破产、失业和坏账。承包商更加重视生产效率和降低成本作为生存手段。一家中小型企业 (SME) 承包商采用行动研究 (AR) 策略来改进其供应链缺陷控制流程。据保守估计，返工通常占项目总成本的约 5%。返工是一种浪费，并且提出了明显的改进目标。这里报告的研究仅涉及 AR 周期的（第一）诊断阶段，包括：现场观察、合同文件分析以及对供应链成员的半结构化访谈。结果表明，供应链参与者有可能确定缺陷的根本原因并提出解决方案，同时考虑避免再次发生的最佳实践。发现缺乏有助于生产改进的协作论坛。此外，用于收集、管理和传播数据的流程是非结构化且不协调的，这表明开发更有效方法的空间。研究结果表明，人们对供应链协作的潜在好处有了很好的理解，但也表明中小企业目前缺乏协作的工具和知识。
Since 2007, Ireland has suffered a circa 80% reduction in construction output. This has resulted in bankruptcy, unemployment and bad debt. Contractors have attached greater emphasis to production efficiency and cost reduction as a means of survival. An action research (AR) strategy was used to improve processes adopted by a small/medium enterprise (SME) contractor for the control of defects in its supply chain. It is conservatively estimated that rework, typically, accounts for circa 5% of total project costs. Rework is wasteful and presents an obvious target for improvement. The research reported here concerns the (first) diagnosing stage of the AR cycle only, involving: observation of fieldwork, analysis of contract documents, and semi-structured interviews with supply chain members. The results indicate potential for supply chain participants to identify root causes of defects and propose solutions, having regard to best practice to avoid reoccurrence. A lack of collaborative forums to contribute to production improvement was identified. Additionally the processes used to collect, manage and disseminate data were unstructured and uncoordinated, indicating scope for developing more efficient methods. The findings indicate a good understanding of the potential benefits for supply chain collaboration but suggest that the tools and knowledge to collaborate are currently lacking in the SME sector.
