Multiteam systems (MTSs) have been employed across numerous organizations and occupations (e.g., healthcare, emergency disaster response, business, and military) to achieve complex goals over time. As MTSs are inherently different than team level and organizational level theories, this chapter highlights the defining features of these dynamic systems through a temporal lens. Thus, the main purpose of our chapter is to address the challenges and issues concerning MTSs over time in order to provide a future agenda to guide researchers and practitioners.

To explore temporality throughout this chapter, we leverage two key MTSs frameworks along with contributions from the literature to produce a review, which demonstrates the extent of MTS theoretical and practical findings. After reviewing the definitional components of MTSs, we highlight various compositional, linkage, and developmental attributes that operate within a system. We then expand upon these attributes to consider the structural features of the system that enhance boundaries between component teams (i.e., differentiation) and may disrupt the system over time (i.e., dynamism).

After reviewing and integrating current MTS literature, we provide a new conceptual framework for MTSs and their temporal complexities. We offer several methodologies that managers and researchers can employ to assess these complex systems and suggest practical recommendations and areas for future research as we continue to study MTSs.

Our original conceptual framework considers MTSs through a dynamic lens developing over time and suggests the need for future research to build upon this perspective.

As work demands have become increasingly complex, organizations and agencies are progressively turning toward larger systems comprised of teams, or multiteam systems (MTSs), to accomplish multifaceted tasks in challenging environments. Today, many organizations require these complex systems in order to achieve the dynamic goals that are required of our ever-changing world. Subsequently, MTSs have become a growing area of interest in organizational research, primarily due to their increasing prominence in organizational settings.

In this introductory chapter, our goal is to highlight a selection of existing research regarding MTSs that serves to answer the question, “What do we know about MTSs?” while also setting up the question that serves as a recurrent theme throughout this volume, “Where does our research need to go in order to better serve MTSs in practice?”

While there has been a great advancement in the area of MTSs in recent years, there is still much to be explored in terms of the challenges and opportunities that MTSs afford in practice.

It is the goal of this chapter that we will set the stage for readers interested in identifying the current trends, dynamics, and issues in MTSs in the real world for the purposes of both expanding our research and theory on MTSs as well as further building the foundation for improving their development, implementation, and effectiveness “in the wild.”

Large-scale and complex issues tend to require a system of interconnected teams (i.e., multiteam systems) that offer more manpower, resources, and flexibility to meet more challenging demands. However, multiteam systems often work within “extreme environments” that can be very stressful, and the impact of this stress can deplete team members’ Well-Being and hinder team performance. Current research on multiteam systems does not address the need to understand how environmental stressors may impact component teams and overall team functioning and how multiteam systems in these environments can regulate stress to overcome these problems. NASA’s spaceflight multiteam system provides a unique example that organizational researchers can look at to understand how the Mission Control team helps regulate stress in the spaceflight team operating within an isolated, confined, and extreme environment. This chapter articulates how NASA’s spaceflight multiteam system stress regulation practices can inform organizational psychologists and advance our understanding of multiteam system functioning.

Meetings can serve the important role of facilitating communication and coordination for systems of teams known as “multiteam systems” (MTSs) that work interdependently to achieve grand societal challenges. Given that MTSs often appear in complex, ambiguous, urgent, and multifaceted task contexts, the MTSs require effective, and efficient but thorough, communication within and between teams in order to achieve shared goals. However, the extant literature regarding the science of meetings has left much to be explored in regard to the inter- and intrateam influences and impacts. This chapter considers the significance of meetings and their practical value in facilitating MTS processes and performance by leveraging what is known thus far regarding MTS structural attributes, their value, their challenges, and opportunities, integrating this foundation with the broader science of meetings. Building on this rationale, the authors move toward empirically and theoretically derived considerations for how meetings may best be designed, facilitated and utilized for MTS effectiveness, as guided by our current understanding of critical MTS attributes.

Although existing research on cohesion provides a robust understanding of the emergent phenomenon in small groups and teams, our comprehension of cohesion at the multisystem (MTS) level is quite limited. The simultaneous within- and between-team functioning inherent in MTSs produces more intricate dynamics than those observed at the team level. This added layer of complexity requires that many familiar team constructs, including cohesion, be systematically re-conceptualized and empirically examined through the lens of MTS theory (DeChurch & Zaccaro, 2010; Hackman, 2003). The present research addresses this gap by extending the conceptualization of team cohesion to the interteam level, and empirically investigating how cohesion functions across levels in a collective network of teams. Results from preliminary research suggest that intrateam and interteam cohesion share a curvilinear relationship with one another, while simultaneously interacting to affect overall system-level outcomes. This research not only illuminates the complexities associated with emergent phenomena in MTSs, but also serves as a starting point for continued, systematic research of the multilevel cohesive bonds that characterize MTS functioning.

Although the practice of multiteam systems (MTSs) has been around for decades, the science of these systems has only just begun. Within the past decade and a half, although much remains to be investigated, substantial progress has been made in breaking the surface of this research. The current volume provides a review of MTS case studies and the current chapter provides a synopsis of this research. The goal of this chapter is to identify how MTSs are operating under real-world conditions in order to bridge MTS science and practice.

In this chapter, the authors provide a case analysis of the presented MTSs in the current volume in order to identify issues innate to MTSs. An approach based on the SWOT analysis technique was utilized to identify strengths, weaknesses, threats, and opportunities of the identified MTSs. In addition, six lessons learned were extracted from a content analysis of the successes and failures of these MTSs.

Although MTSs may be unique to the environment in which they operate, there are several features which seem to be inherent to all. Strengths include possessing the ability to manage complex tasks and unexpected events, being flexible in nature, and integrating communication across levels. In opposition, weaknesses include the use of nontraditional communication patterns, challenges stemming from unit diversity and resources, and the lack of common training. Lessons learned from identified MTSs include (1) utilize effective communication; (2) establish shared mental models; (3) identify roles and responsibilities; (4) convey accountability and ownership; (5) consider the ramp-up period; and (6) train individuals in an MTS at multiple levels. Opportunities and threats to MTSs are also discussed in this chapter.

This chapter offers several contributions to the state of the field in regard to MTSs. The current chapter provides a detailed content analysis of several real-world MTSs. Characteristics inherent to MTSs are identified and discussed, and lessons learned are extracted. Traditionally, science and practice has focused on the presentation of lab-based MTSs; the current volume breaks new ground by identifying how MTSs operate “in the wild.” This chapter provides a summation of this volume and offers lessons learned for MTS researchers and those working within MTSs.

In this chapter, we raise awareness of the larger network in which multiteam systems (MTSs) are situated. We posit that in the complex operations conducted by military units, MTSs are not isolated entities, but rather exist in exponentially complex systems that include additional challenges for both research and practice.

An operational example involving an Army Brigade Combat Team Headquarters is presented to explain the details of the exponentially complex MTSs inherent in military operations, raise awareness about challenges that plague successful mission accomplishment, and discuss the way forward for research and practice.

The Army Brigade Combat Team Headquarters is characterized as a traditional MTS, embedded in a system of hierarchical MTSs, further embedded within a parallel structure of MTSs. Challenges inherent in these organizational structures provide direction for research and practice to address the exponentially complex meta-systems that are prevalent throughout the military.

While researchers have begun to address teams existing in larger networks, or MTSs (Mathieu, Marks, & Zaccaro, 2001), much of the existing research is based on small or isolated systems. As a result, our understanding of the meta-systems in which many of these MTSs exist is limited. This chapter provides concrete examples of an exponentially complex MTS within a military environment and highlights challenges to be addressed in both research and practice.

Group interaction networks are networks whose relations are defined by who engages with whom in communication, coordination, or other forms of joint activity. These interaction networks represent the patterns of action that unfold between members of a group and have the potential to inform research on how groups communicate, how psychological states inform, and how communication patterns can impact team performance. Interaction networks are unique in that they can be defined in terms of both structure and temporality; each interaction can be coded as an event that occurs at a specific point in time. Accordingly, interaction networks are well suited for process theories and methods. Further, the growing availability of fine-grained digital trace data makes it easier for researchers to study these networks in depth. In this chapter, theories of structure and time are reviewed in relation to group networks and interactions. A process-oriented relational event-based paradigm for studying group interaction networks is introduced as a possible alternative to prior methods. The chapter concludes with a comparison of relevant social network approaches, as well as a discussion of potential future research.

The purpose of this chapter is to illustrate some of the complexities and decision points that must be made while attempting to collect data on multiteam systems (MTSs).

An integration of the literature along with prior experience in collecting data on MTSs in both field and laboratory environments was used to identify a series of challenges, decision points, and mitigation strategies.

Ten challenges and corresponding decision points were identified with respect to collecting data on MTSs. Specifically, seven challenges were identified that are associated with defining the research context, two with methodology and measurement, and three related to management and analysis of the collected data. While the challenges presented here are by no means the only challenges and considerations, they are some of the more frequent ones.
