This research investigates growth inhibitors for smart services driven by condition-based maintenance (CBM). Despite the fast rise of Industry 4.0 technologies, such as smart sensoring, internet of things, and machine learning (ML), smart services have failed to keep pace. Combined, these technologies enable CBM to achieve the lean goal of high reliability and low waste for industrial equipment. Equipment located at customers throughout the world can be monitored and maintained by manufacturers and service providers, but so far industry uptake has been slow. The contributions of this study are twofold. First, it uncovers industry settings that impede the use of equipment failure data needed to train ML algorithms to predict failures and use these predictions to trigger maintenance. These empirical settings, drawn from four global machine equipment manufacturers, include either under- or over-maintenance (i.e., either too much or too little periodic maintenance). Second, formal analysis of a system dynamics model based on these empirical settings reveals a sweet spot of industry settings in which such inhibitors are absent. Companies that fall outside this sweet spot need to follow specific transition paths to reach it. This research discusses these paths, from both a research and practice perspective.

本研究调查了由基于状态的维护(CBM)驱动的智能服务的增长抑制因素。尽管智能传感、物联网和机器学习(ML)等工业 4.0 技术迅速崛起,但智能服务却未能跟上步伐。这些技术相结合,使 CBM 能够实现工业设备高可靠性和低浪费的精益目标。制造商和服务提供商可以对位于世界各地客户处的设备进行监控和维护,但迄今为止,行业对这些技术的吸收还很缓慢。本研究有两方面的贡献。首先,它揭示了阻碍使用设备故障数据的行业环境,这些数据是训练 ML 算法预测故障并利用这些预测触发维护所必需的。这些经验环境来自全球四家机器设备制造商,包括维护不足或维护过度(即定期维护过多或过少)。其次,基于这些经验设定的系统动力学模型的正式分析揭示了不存在此类抑制因素的行业设定的甜蜜点。在这个甜蜜点之外的公司需要遵循特定的过渡路径才能达到甜蜜点。本研究从研究和实践的角度讨论了这些路径。

When making decisions about their commitments to environmental practices and performance, suppliers face heterogenous institutional logics and their diverse prescriptions for action. How do suppliers respond to such institutional complexity? We examine this question in the context of suppliers' voluntary public environmental disclosures (disclosure). Specifically, our study assembles a unique panel data set of global manufacturing suppliers and their annual contractual relationships with buyers. Building on the institutional logics perspective and the sustainable supply network literature, we hypothesize that suppliers selectively mimic the disclosure of their buyers by following market, corporate, and sustainability logics. Our study contributes to the institutional logics perspective and the sustainable supply network literature by indicating that in the context of disclosure, market and sustainability logics both actively shape suppliers' responses to institutional complexity. Furthermore, we find support for mimicry as a mechanism of buyer influence that can lead to disclosure heterogeneity across suppliers even when they follow the same logic, which opens new avenues for research. Our findings can be leveraged by buyers, policymakers, and other stakeholders interested in advancing transparency and sustainability in supply networks.

当供应商就其环境实践和绩效承诺做出决策时,他们面临着不同的制度逻辑及其对行动的不同规定。供应商如何应对这种制度的复杂性?我们在供应商自愿公开环境信息披露(披露)的背景下研究了这一问题。具体来说,我们的研究收集了全球制造业供应商及其与买方年度合同关系的独特面板数据集。在制度逻辑视角和可持续供应网络文献的基础上,我们假设供应商通过遵循市场、企业和可持续发展逻辑,有选择性地模仿买方的信息披露。我们的研究表明,在信息披露的背景下,市场逻辑和可持续发展逻辑都会积极影响供应商对制度复杂性的反应,从而为制度逻辑视角和可持续供应网络文献做出了贡献。此外,我们还发现模仿是买方影响的一种机制,即使供应商遵循相同的逻辑,模仿也会导致不同供应商披露信息的异质性,这为研究开辟了新的途径。买方、政策制定者和其他对提高供应网络透明度和可持续性感兴趣的利益相关者可以利用我们的研究结果。

Disasters affect hundreds of millions of people every year and the response of governments is crucial in alleviating the suffering of those affected. Despite the importance of contracting in response to disasters, research on this topic is conspicuous by its absence. This paper begins to address this gap by investigating the choice of procurement contract type by US federal agencies during disaster management operations. The research relies on 47,560 contracts issued by the US federal government in response to 14 major disasters between 2005 and 2016. We build on agency theory to investigate the choice of the contract type made by federal agencies at the different stages of a relief operation. This research provides empirical evidence of the key factors underpinning the choice of contract in the context of disaster management, namely the amount of spend per contract and the type of acquisition (product or service), and reveals the moderating role of the stage of the relief operation.

每年都有数以亿计的人受到灾害的影响,而政府的应对措施对于减轻灾民的痛苦至关重要。尽管在应对灾害时签订合同非常重要,但这方面的研究却明显不足。本文通过调查美国联邦机构在灾害管理行动中对采购合同类型的选择,开始填补这一空白。研究依据的是美国联邦政府在 2005 年至 2016 年间为应对 14 次重大灾害而签发的 47560 份合同。我们以代理理论为基础,研究了联邦机构在救灾行动不同阶段对合同类型的选择。这项研究为灾害管理背景下合同选择的关键因素(即每份合同的支出金额和采购类型(产品或服务))提供了经验证据,并揭示了救灾行动阶段的调节作用。

Supply chain representation on the board of directors and firm performance: A balance of relational rents and agency costs 董事会中的供应链代表与公司业绩:关系租金与代理成本的平衡

Appointing individuals drawn from suppliers and customers to a firm's board of directors is an increasingly popular practice that can enhance the interorganizational relationship and generate relational rents. Yet, such board members may act in the best interest of their primary employer rather than the shareholders of the firm whose board they serve on, thus creating potential agency conflicts. Drawing on the relational view and agency theory, we explore the tension between rent generation and agency costs and consider how a firm can design governance mechanisms to effectively leverage customer or supplier representation on the board of directors. The associated hypotheses are tested using a large panel dataset constructed from multiple archival sources, and our findings suggest that supplier and customer board members are a double-edged sword: While they generate value in some instances, they can also be associated with lower performance depending on the levels of two key governance mechanisms—the number of inside directors on the board and the proportion of outcome-based board member compensation.

任命来自供应商和客户的个人进入公司董事会是一种日益流行的做法,这种做法可以加强组织间关系并产生关系租金。然而,这些董事会成员可能会从其主要雇主的最佳利益出发,而不是从其所在董事会的公司股东的最佳利益出发,从而产生潜在的代理冲突。借鉴关系观点和代理理论,我们探讨了租金产生和代理成本之间的矛盾,并考虑了企业如何设计治理机制,以有效利用客户或供应商在董事会中的代表权。我们的研究结果表明,供应商和客户董事会成员是一把双刃剑:虽然他们在某些情况下会产生价值,但根据两个关键治理机制--董事会内部董事人数和基于结果的董事会成员薪酬比例--的水平,他们也可能与较低的绩效相关联。

This research examines the impact of leader disability status on the operational performance of teams that include individuals with disabilities (IWD) using longitudinal micro-data from an apparel manufacturing company in a competitive integrative employment environment. To aid in developing the research hypotheses and in interpreting the empirical findings, the quantitative analysis is complemented with qualitative data collected through interviews involving managers and workers with and without disabilities at the focal firm and two other large companies that employ IWD. A beneficial moderating effect of leader-worker disability status similarity on team performance is hypothesized and subsequently tested using Prais-Winsten regression. The results show that a leader with a disability has a potentially beneficial impact on team performance as the number of workers with disabilities in the team increases, resulting in improved productivity (measured in labor hours per garment) and quality (measured in operator defects per garment). The theoretical, managerial, and policy implications of the study provide actionable insights for the creation of an inclusive labor force.

本研究利用一家处于竞争性综合就业环境中的服装制造公司的纵向微观数据,研究了领导者的残疾状况对包括残疾人在内的团队运营绩效的影响。为了帮助提出研究假设和解释实证研究结果,本研究在进行定量分析的同时,还通过访谈的方式收集了定性数据,访谈对象包括该重点公司和另外两家雇用残障人士的大型公司的残障和非残障管理人员和工人。假设领导者与员工的残疾状况相似性对团队绩效有有利的调节作用,并随后使用普雷斯-温斯顿回归法进行了检验。结果表明,随着团队中残疾工人数量的增加,残疾领导者对团队绩效有潜在的有利影响,从而提高生产率(以每件服装的工时衡量)和质量(以每件服装的操作缺陷衡量)。本研究的理论、管理和政策意义为创建包容性劳动力队伍提供了可操作的见解。

As the US healthcare system transitions from volume to value, various value-based programs tie medical reimbursements to hospital performance relative to national top performers (i.e., benchmarks). However, prior studies report very limited results on how such benchmarks affect care delivery and patient outcomes across multiple performance fronts. This study examines how general acute care hospitals progress toward benchmarks measured by performance frontiers in technical efficiency, clinical quality, and patient experience over time, subjecting to external market conditions and internal focuses. Based on a panel dataset comprising hospitals in California from 2012 and 2019, our results find support for competitive-distance-driven progression rates, suggesting that hospitals' competitive positions measured by their distances to benchmarks drive performance improvements. Yet, the effect diminishes as they move closer to performance frontiers. In addition, we find that market competition reduces the progression rate of technical efficiency. Finally, our results also suggest that focus improves performance progression rates, yet its effects are curvilinear.

随着美国医疗保健系统从数量型向价值型转变,各种基于价值的计划将医疗补偿与医院相对于全国最佳表现者(即基准)的表现挂钩。然而,之前的研究报告对这些基准如何影响医疗服务的提供和患者在多个绩效方面的结果却非常有限。本研究探讨了在外部市场条件和内部关注点的影响下,综合急症护理医院如何逐步实现技术效率、临床质量和患者体验方面的绩效前沿基准。基于 2012 年至 2019 年加利福尼亚州医院的面板数据集,我们的研究结果发现,竞争距离驱动的进步率得到了支持,这表明以医院与基准的距离衡量的医院竞争地位推动了绩效的提高。然而,当医院越接近绩效前沿时,这种影响就越小。此外,我们还发现市场竞争会降低技术效率的进步率。最后,我们的研究结果还表明,专注会提高绩效进步率,但其影响是曲线性的。

The increased digitalization of shop floors has provided unprecedented opportunities for real-time sharing of process and resource details. Visualization boards (VBs), which provide ubiquitous technology-enabled renderings of such details, salient to a local shop-floor setting, have the potential to play a significant role in this regard. Critical to the effectiveness of this role is the fit between VB design and shop-floor needs. In our study, we apply task-technology-fit theory in case examinations focused on identifying mismatch, implications of mismatch, and putative best practices in designs for future interventions. Our assessment capitalizes on both core operations management design principles as well as technology management design principles. We develop grounded propositions regarding guidelines that should be applied in future VB designs and deployments.

车间数字化程度的提高为实时共享工艺和资源细节提供了前所未有的机会。可视化展板(VBs)通过技术手段为这些细节提供无处不在的渲染效果,突出了当地车间的环境,有可能在这方面发挥重要作用。这一作用能否有效发挥,关键在于 VB 设计与车间需求之间的契合度。在我们的研究中,我们将任务-技术-匹配理论应用于案例研究,重点是识别不匹配、不匹配的影响以及未来干预设计中的最佳实践。我们的评估利用了核心运营管理设计原则和技术管理设计原则。我们就未来虚拟局域网设计和部署中应采用的指导原则提出了有依据的建议。

Into the unknown? Explaining management nonresponse after a supply-base disruption 陷入未知?解释供应基地中断后管理层未作出反应的原因

The world is witnessing more supply-base disruptions, where multiple suppliers of a buying firm simultaneously experience disturbed operations. Compared to single-supplier disruptions, supply-base disruptions create a more uncertain situation for a purchasing manager, yet they can also reveal improvement opportunities. Hence, it is theoretically and practically valuable to understand why a purchasing manager might not be willing to explore these opportunities. Adopting a sensemaking perspective, we investigate how two dimensions of supply-base disruption severity, breadth and depth, influence managers' perception of disruption severity and post-recovery action (i.e., suggesting supply-base restructuring ideas). We conducted multiple scenario-based experiments with practitioners and triangulated the experimental results with interviews, finding that both breadth and depth have diminishing, positive effects on perceived severity. Interestingly, depth is less influential than breadth. These findings reveal the circumstances under which the severity of a complex, disruptive situation could be misestimated. Our results also show that supply-base structural complexity (a cue of the task environment) amplifies the positive effect of perceived severity on a manager's inclination to walk into the unknown to propose supply-base restructuring ideas. These findings provide an explanation for management nonresponse after a supply-base disruption.

世界上出现了越来越多的供应基地中断现象,即一家采购公司的多个供应商同时出现业务中断。与单一供应商中断相比,供应基地中断会给采购经理带来更多不确定因素,但同时也会带来改进机会。因此,了解采购经理为何不愿意探索这些机会具有理论和实践价值。我们从感性认识的角度出发,研究了供应基地中断严重性的两个维度--广度和深度--如何影响采购经理对中断严重性的感知以及恢复后的行动(即提出供应基地重组建议)。我们对从业人员进行了多个基于情景的实验,并将实验结果与访谈结果进行了三角测量,发现广度和深度对感知的严重性都有递减的积极影响。有趣的是,深度的影响要小于广度。这些发现揭示了在何种情况下,复杂的破坏性情况的严重性可能会被错误估计。我们的研究结果还表明,供应基地结构的复杂性(任务环境的线索)会放大感知到的严重性对管理者提出供应基地重组想法的积极影响。这些发现为供应基地中断后管理层不作出反应提供了解释。

These findings provide an explanation for management nonresponse after a supply-base disruption.</p>","PeriodicalId":51097,"journal":{"name":"Journal of Operations Management","volume":"70 8","pages":"1213-1233"},"PeriodicalIF":6.5,"publicationDate":"2023-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139067337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rethinking Six Sigma: Learning from practice in a digital age 反思六西格玛:数字时代的实践学习

<p>As scholars in the field of operations management (OM), we would like to suggest that our field fell short in terms of due diligence when transitioning from statistical process control (SPC) to Six Sigma—accepting without scrutiny, building theory around, and teaching heuristics and algorithms without recognizing its underlying statistical inaccuracies. It is our view that these incorrect heuristics and algorithms have introduced bias and inefficiencies in process improvement throughout the OM field, contributing to a disconnect between OM and knowledge development in data science more generally. We call for a return to first principles and the establishment of formal conceptual definitions for the theory and methods underlying Six Sigma. We urge the OM academic community to embrace the lessons from SPC and Six Sigma so that we prioritize our due-diligence role, beginning with a requirement that all algorithms and tools be vetted before entering our curricula and case-study repertoires, especially as we move forward into an age of big data and potentially further opaque algorithms and tools. We propose that our top journals be open to research that scrutinizes methods developed in practice, so that OM will continue to be the focal field for quality assurance—even when the “product” of a process is data.</p><p>The application of statistical methods to quality management has been a central theme in OM since Shewhart's seminal work at Western Electric's Hawthorne Works nearly a century ago (Shewhart, <span>1925</span>; Shewhart, <span>1926</span>). He studied process variation to determine “how and under what conditions observations may contribute to a rational decision to change or not a process to accomplish improvements” (W. Edwards Deming, p.i, in the foreword of the 1986 edition of Shewhart, <span>1931</span>). His work fostered methods and tools to monitor, diagnose, measure, reduce, and control variation in the output of a process to increase its consistency and capability.</p><p>The capability of a process with respect to a process parameter hence can be defined as the number of standard deviations (“sigmas”) of the parameter that fit between the mean for that parameter and its specification limits. If the process is not centered between the specification limits, then the process capability is set using whichever specification limit is closer to the process center. Six Sigma moves the concept of process capability from descriptive to prescriptive. At the time that Motorola's process-improvement ideas were proposed by Bill Smith in 1986 (Harry, <span>1994</span>), process capability was defined in terms of specification limits set three standard deviations from the process mean (a “3<i>σ</i> process”). Following Shewhart's logic, a centered and normally distributed 3<i>σ</i> process is expected to produce 2700 parts-per-million (ppm) pieces that are more than three standard deviations from the process mean.</p><p>Motorola quantified the “z
作为运营管理(OM)领域的学者,我们想说的是,在从统计过程控制(SPC)过渡到六西格玛的过程中,我们的领域没有尽到应有的责任--在没有认识到其背后的统计不准确性的情况下,不加审查地接受、围绕其建立理论并传授启发式方法和算法。我们认为,这些不正确的启发式方法和算法给整个运营管理领域的流程改进带来了偏见和低效,导致运营管理与数据科学知识发展之间出现脱节。我们呼吁回归第一原则,为六西格玛的基础理论和方法建立正式的概念定义。我们敦促OM学术界接受SPC和六西格玛的教训,从而优先考虑我们的尽职调查角色,首先要求所有算法和工具在进入我们的课程和案例研究之前都必须经过审查,尤其是在我们迈入大数据时代,算法和工具可能会更加不透明的情况下。我们建议,我们的顶级期刊对在实践中开发的方法进行严格审查的研究持开放态度,这样,OM 将继续成为质量保证的重点领域--即使过程的 "产品 "是数据。自 Shewhart 近一个世纪前在西电霍桑工厂的开创性工作(Shewhart,1925 年;Shewhart,1926 年)以来,统计方法在质量管理中的应用一直是 OM 的核心主题。他研究流程变异,以确定 "观察结果如何以及在何种条件下有助于做出合理决策,改变或不改变流程以实现改进"(W. Edwards Deming,第 i 页,见《Shewhart,1931》1986 年版前言)。他的工作促进了监控、诊断、测量、减少和控制流程输出变异的方法和工具,以提高流程的一致性和能力。因此,流程在流程参数方面的能力可定义为该参数的标准偏差("西格玛")的数量,该数量介于该参数的平均值和规格限制之间。如果流程的中心不在规格限制之间,那么流程能力的设定就以更接近流程中心的规格限制为准。六西格玛将过程能力的概念从描述性转变为规范性。1986 年,比尔-史密斯(Bill Smith)提出摩托罗拉流程改进理念时(Harry,1994 年),流程能力的定义是在流程平均值的三个标准差("3σ 流程")范围内设定规格限制。按照 Shewhart 的逻辑,一个居中且正态分布的 3σ 过程预计将生产出 2700 个与过程平均值相差 3 个标准偏差以上的百万分之件(ppm)。摩托罗拉公司通过将过程中心与最严格规格限制之间的标准偏差数转化为百万分之缺陷,量化了 "零缺陷 "理念,该理念是 Crosby(1979 年)等流行且有影响力的作者提出的 "质量是免费的 "论点的核心。在过去,人们认为 3σ 的工艺能力已经足够好了。然而,在许多情况下,3σ 工艺能力所产生的 2700 ppm 的不合规格工件是过高的。哈利认为比尔-史密斯提出了更高的要求:"比尔的提议非常简单。他建议摩托罗拉应要求其所有关键产品性能特征的设计余量为 50%"(Harry,2003 年,第 1 页)。这个缓冲区在平均值和规格限制之间又增加了三个标准偏差(如图 1 所示),标志着 "六西格玛 "概念的诞生。到此为止,摩托罗拉公司的方法可以看作是在简单应用过程能力理论的基础上增加了直觉和目标设定的协议。如果摩托罗拉公司的项目就此打住,一个经过改进的、更加严格的规程可能就会出现,从而对应用于大批量、重复性生产的 SPC 进行渐进但非常合理的扩展。遗憾的是,事实并非如此。应用这些核心概念的几种方法--当时实际应用的局限性的产物--如今已难以自圆其说。在下面的小节中,我们将讨论这些遗留问题中比较突出的几个,以及如何在当前的实践、教学和研究中重新评估和解决这些问题。我们的目的并不是要否认六西格玛的实施在过去几十年中对许多公司产生的积极影响,也不是要诋毁作为 SPC 基础的久经考验的启发式方法。 我们力图引起人们的注意,并纠正本领域长期以来未能利用同行评审程序来澄清六西格玛的统计主张,以及更新过程能力和 SPC,使决策者能够充分理解地使用这些工具。同行评审研究旨在消除这种误解和神秘感,促进将实践世界中出现的有趣想法转化为扎实的知识增长。在同行评审发挥作用之前,顶级期刊有必要对投稿持开放态度,而投稿的贡献就是这种尽职调查。20 世纪 90 年代中期,当六西格玛兴起并引起巨大反响时,人们认为顶级 OM 期刊并不欢迎这类投稿。苏里和德-特雷维尔(Suri and de Treville,1986 年)在 JOM 上发表了一篇概念性文章,为我们所呼吁的事实核查开辟了道路。20 世纪 80 年代初,"岩石与溪流 "的概念开始流行:当时的说法是,随着库存从系统中移除,由此产生的生产线停工将导致学习。Suri 和 de Treville 详细探讨了当中间库存减少时,两个工作站之间会发生什么。当一个工作站堵塞或饿死另一个工作站时,学习就会发生,但这种堵塞和饿死也可能导致学习失败。这一学术探讨有助于我们更细致地理解库存减少与学习之间的关系。允许这些 SPC 和六西格玛方法不受质疑、一成不变地存在,已经造成了混乱,并阻碍了 OM 理论和工具的发展,使其无法应对当今数据丰富的环境。现代统计质量监控系统不是分析人工从生产线上收集的小样本数据,而是以数字形式自动生成高频率的实时数据。通过将 SPC 和流程能力与合理的统计原理联系起来,我们就能够使用 OM 思维和工具对物联网(IoT)和实时定位与传感等系统进行评估。我们呼吁 OM 社区坚持将流程能力和 SPC 回归到可靠的统计基础和正式的概念定义上来,认识到六西格玛是来自实践世界的协议,它引发了重要的讨论,但其基本假设存在根本性缺陷。如果我们要与质量保证和数据科学领域正在发生的事情保持关联,这种回归是必不可少的。我们进一步呼吁 JOM 成为一本欢迎将实践中的想法引入同行评审的期刊,从而以知识的扎实增长取代对神奇调味汁的盲目信仰。
