An exact approach for the balanced <Emphasis Type="Italic">k</Emphasis>-way partitioning problem with weight constraints and its application to sports team realignment

In this work a balanced k-way partitioning problem with weight constraints is defined to model the sports team realignment. Sports teams must be partitioned into a fixed number of groups according to some regulations, where the total distance of the road trips that all teams must travel to play a double round robin tournament in each group is minimized. Two integer programming formulations for this problem are introduced, and the validity of three families of inequalities associated to the polytope of these formulations is proved. The performance of a tabu search procedure and a branch and cut algorithm, which uses the valid inequalities as cuts, is evaluated over simulated and real-world instances. In particular, an optimal solution for the realignment of the Ecuadorian football league is reported and the methodology can be suitable adapted for the realignment of other sports leagues.     

Self-management competencies in self-managing teams: Their impact on multi-team system productivity

This research examined how composition of individual capabilities within self-managed teams translates into greater effectiveness for multi-team systems (MTS) in which teams are embedded. We investigated how a broad range of self-management competencies by team members aggregate to form a collective construct that influences productivity of a team network. In a semiconductor plant, we surveyed 716 members from 97 self-managed teams in 21 MTS. We found that MTS comprising teams whose members widely practice self-management strategies attain higher productivity gains and that multi-team systems consisting of highly cohesive teams of self-managers are the most productive.     

How and When Servant Leaders Enable Collective Thriving: The Role of Team–Member Exchange and Political Climate

Thriving teams are critical to the effective functioning of an organization. Extending Spreitzer et al.’s (2005) socially embedded model of thriving at work to the team level, this study explores how and when servant leadership promotes collective thriving. Through data collected from 80 teams composed of 520 employees, the study reveals that servant leaders help embed members in high‐quality team–member exchange relationships, which in turn enables their collective thriving. The authors find that a highly political climate is a dual‐stage moderator hindering the positive impact of servant leadership on collective thriving. The findings move forward extant servant leadership and thriving literature. The authors also offer practical implications for how organizations can nurture and reap benefits from thriving teams and the active role of employees in this process.     

Mind the gap: The role of leadership in multiteam system collective cognition

The increasing prevalence of team-based organizations places a premium on leadership that will “mind the gap” and enable smooth synchronization of activities across multiple distinct teams. Prior work shows that leaders can be trained to directly facilitate between-team coordination processes. Yet, relatively little is known about the intervening psychological mechanisms that enable between-team coordination. Here, we advance multiteam-interaction mental models—cognitive structures containing knowledge of appropriate between-team activities—as one mechanism that facilitates coordination among multiple teams. We use leader and team cognition data gathered in DeChurch and Marks' (2006) MTS study to test these ideas. Results reveal leaders' multiteam-interaction mental model accuracy “transfers” to teams through strategic communication, and leader strategic communication enables between-team coordination by promoting accuracy in followers' mental models. This study highlights the importance of leadership for developing collective cognition that allows teams to “scale up” from small stand-alone teams to larger and more complex systems.

Harnessing Diversity and Collective Action in the Top Management Team

Diversity has become an important issue at all levels of the company from the boardroom to the back office. It is increasingly apparent that diversity is vital to productivity, with academic research indicating an important link between diverse top management team (TMT) composition and corporate performance. However, the nature of this link remains elusive, as there is little accessible research that can help top teams to evaluate how diversity impacts on their strategic capacity. This paper seeks to fill this gap by developing a conceptual framework, illustrated with case examples, to explain the relationships between TMT diversity and TMT collective action. As collective action is difficult to attain from top teams that are high in diversity, six practical processes are developed from this framework for establishing and exploiting top team strategic capacity. The paper concludes by outlining the theoretical implications of the framework.

It is the range of skills and attributes acquired through a diversity of experiences and backgrounds that combine to create a cohesive and effective board.¹

     

Path to “Stardom” in Globally Distributed Hybrid Teams: An Examination of a Knowledge‐Centered Perspective using Social Network Analysis

Although distributed teams have been researched extensively in information systems and decision science disciplines, a review of the literature suggests that the dominant focus has been on understanding the factors affecting performance at the team level. There has however been an increasing recognition that specific individuals within such teams are often critical to the team's performance. Consequently, existing knowledge about such teams may be enhanced by examining the factors that affect the performance of individual team members. This study attempts to address this need by identifying individuals who emerge as “stars” in globally distributed teams involved in knowledge work such as information systems development (ISD). Specifically, the study takes a knowledge‐centered view in explaining which factors lead to “stardom” in such teams. Further, it adopts a social network approach consistent with the core principles of structural/relational analysis in developing and empirically validating the research model. Data from U.S.–Scandinavia self‐managed “hybrid” teams engaged in systems development were used to deductively test the proposed model. The overall study has several implications for group decision making: (i) the study focuses on stars within distributed teams, who play an important role in shaping group decision making, and emerge as a result of a negotiated/consensual decision making within egalitarian teams; (ii) an examination of emergent stars from the team members’ point of view reflects the collective acceptance and support dimension decision‐making contexts identified in prior literature; (iii) finally, the study suggests that the social network analysis technique using relational data can be a tool for a democratic decision‐making technique within groups.     

Leader self-projection and collective role performance: A consideration of visionary leadership

Leaders often need to project themselves into alternative situations, but there is a limited understanding of how, why, or when leader self-projection might influence their teams’ outcomes. Based on the notion that brain activity in the default mode network (DMN) underlies self-projection, such as future-oriented mental simulations, we argue that the effect of leaders’ DMN activity on team behavior such as collective role performance may be understood by considering both the leaders’ visionary behavior and their orientation towards socialized vision. Specifically, we posit that a leader’s trait-like brain activity in the leader’s DMN is associated with the leader’s visionary behavior. Furthermore, we argue that visionary leader behavior, when accompanied by socialized vision orientation, facilitates collective role performance of the team. As such, we examine the moderating role of a socialized orientation toward serving the interests of a wide range of stakeholders in reinforcing the positive effect of visionary leader behavior on collective role performance of team members, as well as the indirect effect of leader DMN activity on collective role performance via visionary leader behavior. We found support for our hypotheses using diverse research methodologies, including quantitative electroencephalogram (qEEG), multi-source multi-wave surveys, and interview coding.     

A THREE-PHASE APPROACH TO INSTILLING A CONTINUOUS LEARNING CULTURE IN MANUFACTURING EDUCATION AND TRAINING

We describe a “learn-by-doing” approach that involves the following three phases designed in part to integrate management and engineering curricula and instill a continuous learning philosophy: (1) involve cross-functional teams as “process and business owners” in a replica of a real-life manufacturing/design problem (Do), (2) require teams to not only learn by doing but to then apply or implement what they have learned in phase 1 (Apply), and (3) share best practices and knowledge gained with subsequent participants (Document). These last two phases are essential and potentially the most valuable but are often ignored in the learning process. They can be accomplished either manually or through the use of an electronic bookshelf (e.g., company or school intranet), which is a database system used to collect and store templates of best practices, collective wisdom, and related information associated with learning and operational activities. We describe two of several educational packages we have developed and discuss their impact on our teaching, our students, and practitioners.     

Creating team ambidexterity: The effects of leader dialectical thinking and collective team identification

In the current, increasingly dynamic environment, more attention is being devoted to ambidexterity (both explorative and exploitative learning), as it is beneficial to organizational functioning. Despite an abundance of research on organizational ambidexterity, there is a paucity of research examining team-level ambidexterity. In a cross-level empirical study, we examine a leader's dialectical thinking as an antecedent of team-level ambidexterity. We also incorporate collective team identification as a moderator in the study. Our findings support that a leader's dialectical thinking can help facilitate team ambidexterity that, in turn, improves employee performance. Those teams whose members have strong team identification and whose leader is high in dialectical thinking will reap the most benefit from team ambidexterity.     

基于创业团队先前经验的新技术企业市场进入战略选择研究

基于社会认知和战略选择等理论知识,探讨创业团队先前经验构成特征与进入战略创新性的逻辑关系,并探索技术独享性和环境宽松性对团队决策的影响。基于随机抽样的问卷调研方法,利用150份新技术企业样本进行实证分析。研究结果表明,新技术企业初始战略来源于创业团队基于先前经验而达成的集体认知决策,技术导向型团队倾向于通过产品或服务的创新进入市场,而市场导向型的团队则会竭力从交易结构的创新入手,兼顾技术和市场导向的团队,虽然拥有多元化的认知模式,却没能迸发出应有的创造力。技术独享性在创业团队经验构成与进入战略创新性之间发挥正向调节作用,但没有改变团队成员固有认知模式;环境宽松性改变了创业团队在选择市场进入战略时的关注点,当环境较为宽松时,技术导向型和市场导向型的创业团队都呈现出对产品或服务创新的忽视,而加大了在交易结构上谋求创新的力度。     

Data analytics effects in major league baseball

The use of data analytics has enjoyed resurgence over the last two decades in professional sports, businesses, and the government. This resurgence is attributable to Moneyball, which exposed readers to the use of advanced baseball analytics by the Oakland Athletics, and how it has resulted in improved player selection and game management. Moreover, it changed managerial vocabulary, as the term “Moneyballing” now commonly describes organizations that use data analytics. The first research question that this study examines is whether the organizational knowledge related to baseball data analytics has provided any advantage in the competitive Major League Baseball (MLB) marketplace. The second research question is whether this strategic advantage can be sustained once this proprietary organizational knowledge becomes public. First, I identify “Moneyball” teams and executives, i.e., those who rely on baseball data analytics, and track their pay/performance over time. Next, using econometric models, I analyze whether these “Moneyball” teams and GMs, have enjoyed a pay-performance advantage over the rest of MLB, and whether this advantage persists after the information becomes public.     

A Dynamic Perspective on Diverse Teams: Moving from the Dual-Process Model to a Dynamic Coordination-based Model of Diverse Team Performance

The existing literature on diverse teams suggests that diversity is both helpful to teams in making more information available and encouraging creativity and damaging to teams in reducing cohesion and information sharing. Thus the extant literature suggests that diversity within teams is a double-edged sword that leads to both positive and negative effects simultaneously. This literature has not, however, fully embraced the increasing calls in the broader groups literature to take account of time in understanding how groups function [e.g. Cronin, M. A., Weingart, L. R., &; Todorova, G. (2011). Dynamics in groups: Are we there yet? The Academy of Management Annals, 5, 571–612]. We review the literature on diverse teams employing this lens to develop a dynamic perspective that takes account of the timing and flow of diversity's effects. Our review suggests that diversity in groups has different short-term and long-term effects in ways that are not fully captured by the currently dominant double-edged sword metaphor. We identify an emerging perspective that suggests a tropical depression metaphor—that has the potential, over time, to develop either into a dangerous hurricane or diffuse into a rainstorm that gives way to sunshine, as more apt to capture the dynamic effects of diversity in teams. We conclude by outlining an agenda for redirecting future research on diverse teams using this more dynamic perspective.     

考虑产能约束的新产品与旧产品预售策略研究

预售商品种类繁多，可分为从未上市过的新产品和已经上市过旧产品。面对不同类型的产品，根据消费者效用理论，消费者可能做出不同的决策。研究在产能约束的前提下，零售商销售不同类型产品的最优预售策略问题。结果表明，新产品的最优预售策略取决于正常销售价格，旧产品的最优预售策略受正常销售价格与消费者构成的共同影响，且前者的影响作用大于后者。较低的正常销售价格或较大的高估值消费者比例增大了消费者在正常销售期购买的缺货风险，零售商应采取溢价预售策略，否则应采取折价预售策略。此外将新产品和旧产品的最优预售策略对比发现，利用消费者对产品估值的不确定性，新产品预售比旧产品预售更具优势。     

Organizational Learning: A Radical Perspective

The teamworking and knowledge management fields are increasingly converging. Teamworking is turned to with a growing disillusion with knowledge management approaches that are seen as excessively 'hard', 'objectified', or 'information technology dominated'. This paper is a critical review, the purpose of which is to survey the literature across several fields that provide insights into teamworking aspects of knowledge management, and the reverse. This approach is chosen as disciplines tend to sustain presumptions and preoccupations that may be contradicted by other fields, as is shown. In particular, the review challenges what is referred to as the 'organizational behaviour textbook theory of teamworking' and refers to research and theory from several disciplines that qualify what is still an influential orthodoxy. The paper attempts to draw together some principles from current themes such as collective mind, modularity, cross-functional teams and communities of practice.

A multilevel study of transformational leadership,identification, and follower outcomes

Using a sample from a large diversified company, this study examines the influence processes of transformational leadership (TFL) at both the individual and group levels concurrently and explores cross-level relationships. Results showed that, at the individual level, followers' personal identification with the leader mediated the effects of individual-focused TFL behavior on individual performance and empowerment. At the group level, group identification mediated the effect of group-focused TFL behavior on collective efficacy. Results also supported two cross-level effects from the group level to the individual level. The paper addresses the implications for leaders of motivating individuals and teams, at the same time.
