A transactive memory system (TMS) is a means by which people may store information externally; in such a system the task of remembering is offloaded by remembering where information is located, rather than remembering the information itself. As Sparrow et al. (2011) suggest in the article Google Effects on Memory: Cognitive Consequences of Having Information at Our Fingertips, people are beginning to use the internet and computers as a TMS, and this use is changing the way people encounter and treat information. The purpose of this thesis is to investigate whether preference for TMS type (either with books or with computers) varies across age groups. An interaction between TMS preference and age was hypothesized. Before the onset of the internet age, information was primarily found in books and other print materials whereas now the internet is more frequently used, thus this shift in thinking and habit across generations was expected to emerge in the data. The study yielded a total of 51 participants, 32 from the young age group (ages 18-24) and 19 from the old (ages 61-81). A modified Stroop task and question blocks (for priming purposes) were employed to examine whether people are prone to think of book- or computer-related sources when in search of information. Also, a "Look up or Learn" tendencies survey was used to better understand how people decide whether certain information should be learned or left to be "looked up" later (Yacci & Rosanski, 2012). The mixed ANOVA did not reveal main effects for question difficulty or TMS type, nor was an interaction with age found. The results were not consistent with those of Sparrow et al. (2011) and did not show significance for TMS preference. Future studies should continue to examine the Google effect and TMS preference, as it bears important applications for a number of fields.

L’organisation fonctionnelle des entreprises impose un fonctionnement en mode projet. Ces projets sont menés par des experts de différentes spécialités et d’origine diverses. Ces équipes ont besoin d’outils pour être performant et proposer des solutions adaptées aux multiples besoins des marchés de plus en plus exigeants. Au cours de leurs réunions et activités, ils se créé une conscience de groupe qui s’enrichit à travers les interactions et s’appuie sur divers représentations externes. Cette thèse aborde l’étude des mécanismes permettant la performance des équipes de conception collaborative en réunion synchrone. Elle a essayé de démontrer les liens entre leur Système de Mémoire Transactive (TMS), leurs Activités de Conception Collaboratives (CDA) et leurs Objets désignés Ressources (RSC), et d’identifier les éléments favorisant ces liens. Nous avons dans un premier temps réalisé une enquête auprès des équipes de conception collaborative en environnement universitaire. Puis dans un second temps nous avons réalisé une expérimentation sur deux équipes en situation de conception collaborative synchrone autour du Serious Game Delta Design déployé sur une table interactive. Les résultats de cette recherche montrent que si la performance est favorisée par la TMS ou la CDA, leur lien statistique est établit, de même que le lien entre les activités de conception et les ressources mobilisées. Cependant, l’absence de lien statistique fort TMS CDA montre que les équipes ne semblent conscientes de l’utilisation des objets dans la construction de leur TMS, alors que les artefacts de la table interactive sont les plus sollicités et les activités de prise de décision semblent les plus importantes dans ces séances.Cette thèse contribue au corpus de connaissance sur l’étude des équipes de conception collaborative et mets à disposition des outils d’évaluation de la performance des équipes de conception collaboratives synchrone. / Today functional structure of enterprises requires teamwork and project mode organization. These projects are carried out by experts from different domains of expertise. Besides the teams need supporting tools in order to improve the efficiency of their design process and to propose adapted solutions to complex design problems. In the course of their meetings and collaborative activities they create group awareness through their interactions and creation of various artifacts. This thesis studies mechanisms that underlie performance of collaborative design team in synchronous meeting. In this thesis we demonstrate the links between Transactive Memory System (TMS), Collaborative Design Activities (CDA) and Objects called Resources (RSC), and identify the elements that drive these links. A survey has been used to study collaborative design teams in academic environment. Then, we performed direct observation of two teams during synchronous collaborative design meetings with a serious game Delta Design on interactive table. Results show that if performance is enhanced statistically by good TMS or CDA, and the link is demonstrate, so is the links between CDA RSC. However, the lack of statistical strong correlation between TMS and RSC seems to show that team members are not conscious of using artifacts during TMS building. While artifacts on interactive table are more solicited and decision making activities seems to be more important during their session. This thesis contributes to a better understanding of collaborative design teams and offers tools to evaluate collaborative design activities.

Context. Large-scale software development projects are those consisting of a large number of teams, maybe even spread across multiple locations, and working on large and complex software tasks. That means that neither a team member individually nor an entire team holds all the knowledge about the software being developed and teams have to communicate and coordinate their knowledge. Therefore, teams and team members in large-scale software development projects must acquire and manage expertise as one of the critical resources for high-quality work. Objectives. We aim at understanding whether software teams in different contexts develop transactive memory systems (TMS) and whether well-developed TMS leads to performance benefits as suggested by research conducted in other knowledge-intensive disciplines. Because multiple factors may influence the development of TMS, based on related TMS literature we also suggest to focus on task allocation strategies, task characteristics and management decisions regarding the project structure, team structure and team composition. Methods. We use the data from two large-scale distributed development companies and 9 teams, including quantitative data collected through a survey and qualitative data from interviews to measure transactive memory systems and their role in determining team performance. We measure teams’ TMS with a latent variable model. Finally, we use focus group interviews to analyze different organizational practices with respect to team management, as a set of decisions based on two aspects: team structure and composition, and task allocation. Results. Data from two companies and 9 teams are analyzed and the positive influence of well-developed TMS on team performance is found. We found that in large-scale software development, teams need not only well-developed team’s internal TMS, but also have well- developed and effective team’s external TMS. Furthermore, we identified practices that help of hinder development of TMS in large-scale projects. Conclusions. Our findings suggest that teams working in large-scale software development can achieve performance benefits if transactive memory practices within the team are supported with networking practices in the organization.

「兩人」是團隊組成的最小單位，回顧人類社會經濟活動的發展，許多重要的創新，經常是從兩人團隊開始。特別是以創意為核心的任務或作為，更易於以兩人為基礎，個別尋覓契合自我價值觀、專業能力，和人格特質的合作搭檔。雖然兩人團隊是人類社會經濟活動的常態，存在著重要的學理和實務意涵需要探討；但是，目前有關兩人團隊的文獻仍不多見。本研究的目的，即在回應此一文獻缺口，探討兩人團隊創意交融的系絡。 研究採取比較個案研究法，以八個兩人設計團隊進行半結構的深度訪談，正式研究前則進行了兩個前導個案的研究。經彙整訪談逐字稿之文本分析內容後，本研究有三個主要發現。第一，兩人設計團隊創意協作的歷程，從成員對產品核心概念的探索開始，之後會經歷共同建構創意、精緻化創意和實踐創意等過程。而產品核心概念的頓悟，通常是兩人在相近的問題意識下，從參與共享的情境當中浮現。此一情境浮現之頓悟並不專屬哪一方，但又必須仰賴兩人共同參與情境而獲得。第二，友誼是促進兩人設計團隊發展交融記憶系統的重要因素，友誼不僅帶動了兩人從玩票接案到正式形成團隊，同時也在團隊運作過程中，增強交融記憶系統本身的能量。第三，成員會透過不同形式的溝通互動，促進資訊的交流並精緻彼此的創意，這些形式包括了競爭型互動、合作型互動，和基於玩興的互動。 整體而言，本研究拓展了吾人對於兩人團隊及其創意交融的理解，也對團隊經營和團隊創意管理的實務有所貢獻。團隊發展實務上，可培養交融記憶系統成為團隊賴以運作的核心能耐，並透過成員共同參與情境的方式，營造有利於兩人從事創意交融活動的場域。 / ‘Two person’ is a basic unit of the composition of a team. Looking back on the historical development of the social and economic activities of the human, many radical innovations were often invented by two-person teams. Especially, creative workers, based on the two-person team structure, are more likely to search for the right partner that whose vision, value, expertise, and personality are best fit with each other. Despite the research on two-person team could provide valuable theoretical and practical implications for team literature; very little attention has given to such phenomena. Using a multi-case of eight two-person design teams, this dissertation explores the creative collaboration within the two-person teams. Through the qualitative analysis of the data, this dissertation provides three major findings. First, the creative collaboration processes within the two-person team contain four stages which begin exploring the core concept of the product. Then, team members collectively co-construct, elaborate and execute the core concept of the product. The insight of core concept of the product usually emerges from the two persons who have similar problem awareness and collectively engage in a shared context. This insight is not exclusive which party, but must rely on both sides to collectively engage in the shared context to develop. Second, friendship plays an important role for facilitating the development of the team’s transactive memory system (TMS). Friendship not only helps the two persons to build a team, help the team’s TMS function well in the team development processes. Third, members within the two-person team use three kinds of dialogue communication for exchanging information and elaborating creative ideas of the members. The three kinds of dialogue are: competitive dialogue, collaborative dialogue, and playfulness dialogue. Overall, this dissertation extends the current knowledge in management area about the creative collaboration within the two-person teams. Results of this dissertation also contribute to the management for two-person teams and the management of team members’ creative ideas. This dissertation suggests the two-person teams can build TMS as a team’s core capability and engage in shared contexts where beneficial for the creative collaboration.
