当传统方法失败时，建筑工程与管理（CEM）研究人员往往依赖于替代研究技术。例如，调查、访谈和集体头脑风暴技术可能不适合涉及混淆因素和需要访问敏感数据的研究。在这样的环境中，德尔菲技术允许研究人员通过使用战略设计的调查从认证专家那里获得高度可靠的数据。目前，德尔菲法在实证研究中尚未得到广泛应用。这可能是由于在CEM研究中实施德尔菲的研究之间存在差异，以及文献中对与该方法相关的具体参数提供指导的模糊性。在本文的指导下，读者可以：(1)了解传统德尔菲法的优点、适当的应用和适当的程序；(2)根据客观准则，甄别合格的专家小组成员；(3)选择适当的研究参数，如小组成员人数、轮次、反馈类型和共识衡量标准；(4)识别可能对结果质量产生负面影响的潜在偏差；(5)适当地组织调查，并以最小化或消除偏见的方式进行调查。
Construction engineering and management (CEM) researchers often rely on alternative research techniques when traditional methods fail. For example, surveys, interviews, and group-brainstorming techniques may not be appropriate for research that involves confounding factors and requires access to sensitive data. In such an environment, the Delphi technique allows researchers to obtain highly reliable data from certified experts through the use of strategically designed surveys. At present, the Delphi method has not seen widespread use in CEM research. This is likely due to variation among studies that implement Delphi in CEM research and ambiguity in literature that provides guidance for the specific parameters associated with the method. Using the guidance in this paper, the reader may: (1) understand the merits, appropriate application, and appropriate procedure of the traditional Delphi process; (2) identify and qualify potential expert panelists according to objective guidelines; (3) select the appropriate parameters of the study such as the number of panelists, number of rounds, type of feedback, and measure of consensus; (4) identify potential biases that may negatively impact the quality of the results; and (5) appropriately structure the surveys and conduct the process in such a way that bias is minimized or eliminated.
