This research develops a methodology for making process improvements that can sustain over time. Working with caregivers at a large U.S. hospital over 3 years, we redesign a process for educating kidney transplant patients with instructions for post-surgical care. Adopting an intervention-based research (IBR) framework and based on our actions to overcome challenges in implementation and sustainment of the redesign, we revise the current understanding of organizational learning theory. Follow-up observations after our intervention show that the process improvements at the hospital are sustained. We supplement the IBR with quantitative analyses and provide evidence of improvements in health outcomes and satisfaction levels of patients associated with the redesign. These analyses are based on difference-in-difference estimations using data from transplant patients, including a control group from other transplant units. Overall, our research specifies a methodology for implementing sustainable process improvements, particularly in high interaction service environments such as healthcare delivery, and identifies refinements to organizational learning theory, especially for such environments.

2、关于做实验设计的选择:关于需求效应、激励、欺骗、样本和小插图的使用和挑战的讨论
在2018年末，Journal of Operations Management发表了一篇由Lonati等人(2018)撰写的方法特约文章，指导作者如何设计行为实验，以达到该期刊所要求的严谨性。这篇文章是对JOM提交的许多行为研究报告的回应，每个报告都涉及有趣的主题，但编辑在开始时认为它们的设计选择很糟糕。虽然Lonati等人(2018)的文章提供了适合某些研究议程的实验指导，但文中仍然存在一些问题，包括是否以及如何准确地实施其中的一些观点，以及如何最好地解决行为实验设计中的权衡。如何将这些概念应用到运营管理研究中也出现了一些问题。本文试图解决这些问题，通过深入研究有关需求影响、激励、欺骗、样本选择和上下文丰富的小插图的研究风险和权衡的细节。JOM社区的大量资深学者提供了支持和反馈，我们试图帮助作者梳理出在设计适合各种研究议程的强行为实验时可以合理地做些什么。
In late 2018, the Journal of Operations Management published an invited methods article by Lonati et al. (2018) to provide guidance to authors on how to design behavioral experiments to achieve the rigor required for consideration in the journal. That article was written as a response to a number of behavioral research submissions to JOM, each dealing with interesting topics but viewed by the editors to possess poor design choices at inception. While the Lonati et al. (2018) piece provides experimental guidance fitting to certain research agendas, questions have arisen concerning whether and how exactly to implement some of the points that it makes, and how to best address trade-offs in the design of behavioral experiments. Questions have also arisen concerning how to apply these concepts in operations management research. This technical note seeks to address these questions, by diving into the details of research risks and trade-offs regarding demand effects, incentives, deception, sample selection, and context-rich vignettes. The authors would like to recognize the input of a large number of senior scholars in the JOM community who have provided support and feedback as we have sought to help authors tease out what can reasonably be done in designing strong behavioral experiments that fit various research agendas.

Firms’ commitment to corporate social responsibility (CSR) can be a crucial factor in supply chain partnerships. This study examines the effect of CSR orientation incongruence on relationship performance. Drawing on the congruence theory literature, we posit that a firm's relationship performance may suffer when there is incongruence between the levels of CSR orientations of supply chain partners. Furthermore, we adopt a network perspective and argue that certain characteristics of a firm's egocentric social network (i.e., network centrality and network diversity) may moderate the linkage between CSR orientation incongruence and relationship performance. Our empirical study, which is based on dyadic data, indeed reveals that a firm's relationship performance is adversely affected when the firm and its major supply partner have incongruent levels of CSR orientations. Such a negative effect is moderated by the firm's egocentric social network. Specifically, the negative impact of incongruent CSR orientation is heightened if the firm occupies a central position in the egocentric network. Network diversity, however, plays a contrasting role as a firm's relationship performance may be less susceptible to incongruent CSR orientations when there is access to a diverse social network.

Based on a multi-year research engagement with practice, we present a novel solution design for frontlog scheduling in aircraft line maintenance and offer theoretical insights into buffer management in operations. The field problem of the case airline was to improve departure reliability for long-haul aircraft without increasing maintenance resources, and without using backup aircraft. Frontlog scheduling is the purposeful introduction of over-maintenance as a buffer of maintenance tasks that can be opportunistically postponed. A detailed simulation of the solution introduced in the airline's operations indicates a performance frontier shift, concurrently improving departure reliability, and reducing maintenance cost. We position the novel practice in operations and maintenance management literature, arguing that the frontlog creates a new type of time buffer, available in contexts where capacity serves predictable as well as unpredictable demand. Further theoretical elaboration leads us to reconceptualize buffer management along time and capacity dimensions, reducing inventory to a special case of time buffering.

Research shows that electronic monitoring technologies can reduce illicit agent (e.g., frontline worker) behavior along monitored dimensions such that principals (e.g., firms) benefit. Drawing on theory from criminology regarding the concept of offense displacement, we explain why the benefits from increased monitoring may be mitigated if agents subsequently increase other types of illicit acts not subject to greater monitoring. We investigate this possibility by examining how a mandate requiring millions of truck drivers to adopt electronic logging devices to record their working hours affected different safety behaviors and outcomes. Using data from millions of driver inspections and crash counts before and after the mandate and a differences-in-differences identification strategy, we find greater monitoring due to the mandate achieved its first-order effect of reducing the frequency that drivers were in non-compliance with work hour rules (the monitored dimension). However, drivers for small firms that were most affected by the mandate also appear to have increased their frequency of unsafe driving (e.g., speeding). We also find that crash counts for small firms did not fall relative to large firms, and may have increased. These results call into question whether increased electronic monitoring has improved safety in this industry.
