Research On The Relationship Among Team Faultlines,Transactive Memory System And Team Performance

In order to gain advantages in the increasingly fierce market competition,it has gradually become one of the main work forms adopted by enterprises to complete work tasks by organizing teams.In recent years,employee diversification has become a basic feature of enterprise personnel structure,which leads to the increasingly diversified attributes of team members in enterprises.The diversity of membership attributes not only brings vitality to the team,but also challenges team management and team effectiveness.On the one hand,under the dynamic aggregation of the same or similar attributes such as members'gender,age,nationality,educational background,profession and functional background,teams are easily divided into multiple homogeneous but heterogeneous sub-teams,the hypothetical dividing line between these sub-teams is the team faultlines.Team faultlines is inevitable and has become an unavoidable problem in enterprise team management.Therefore,we need to face up to the impact of team faultlines on team process and team performance.On the other hand,team diversification is manifested in the differences of members'expertise,such as knowledge and skills.How to effectively manage,coordinate and complement the heterogeneous characteristics of team members,and promote the collaboration of team members in the process of team work,so as to achieve the value of team cognitive resources is one of the major challenges facing organizations.According to the above practical problems,based on I-P-O model,synergetics and other related theories,the study constructs a research model describing the relationship among team faultlines(social categorization faultlines and information recognition faultlines),transactive memory system and team performance,aiming to reveal the impact of team faultlines and transactive memory system on team performance,the mediating role of transactive memory system in the relationship between team faultlines(social categorization faultlines and information recognition faultlines)and team performance,and the mediating role of exploratory learning and exploitative learning in the relationship between transactive memory system and team performance.Specifically,the study mainly includes the following contents:First of all,through combing and summarizing the literature at home and abroad,we can understand the development process and research status of team faultlines,transactive memory system,exploratory learning,exploitative learning and team performance,so as to grasp the shortcomings of existing research and the research fields that need to be further explored.And then,on the basis of defining the concepts of team faultlines,transactive memory system,exploratory learning,exploitative learning and team performance,the paper proposes the possible logical relationship between variables based on relevant theories,and constructs a research model.At the same time,13 hypotheses are put forward to reveal the mechanism of team faultlines and transactive memory system on team performance,i.e.,social categorization faultlines has a negative impact on team performance,information recognition faultlines,transactive memory system,exploratory learning and exploitative learning all contribute to improving team performance,and transactive memory system can mediate social categorization faultlines and information recognition faultlines on team performance,transactive memory system can also indirectly affect team performance through exploratory learning and exploitative learning.The study collects data through questionnaire survey,taking project teams in enterprises as research objects,and obtains 255 valid questionnaires from 44 project teams.The reliability and validity of the collected data are tested by homologous deviation test,reliability test and validity test,and the research hypotheses are tested by using multiple regression analysis and Bootstrap method.The results of data analysis show that social categorization faultlines has a significant negative impact on team performance,information recognition faultlines has a significant positive impact on team performance,and transactive memory system can partly mediate the relationship between social categorization faultlines,information recognition faultlines and team performance.Transactive memory system not only has a significant positive impact on team performance,but also indirectly affects team performance through exploratory learning and exploitative learning.In the end,the paper discusses the results of empirical analysis and puts forward practical enlightenment in order to provide theoretical guidance for the development of practice.Finally,the possible innovation points and future research directions are proposed.The main contributions of the study are as follows:Firstly,the relationship between team faultlines and team performance is clarified.Based on the difference of members'attributes,the team faultlines is divided into social categorization faultlines and information recognition faultlines,and the effects of two kinds of team faultlines on team performance are discussed respectively.Empirical studies are conducted to examine the differences in the roles of social categorization faultlines and information recognition faultlines in team performance,and to explain the differences in existing studies.The conclusion of the study is helpful for managers to rationally view team faultlines,fully consider the attributes of team members in team formation,and provide references for managers in recruiting team members.Secondly,it further opens up the"black box"of the role of team faultlines on team performance,and enriches the research on the intermediary mechanism between team faultlines and team performance.That is,introducing the variables of transactive memory system to analyze the mediating effect between team faultlines(social categorization faultlines and information recognition faultlines)and team performance,and verifying the mediating effect of transactive memory system through empirical analysis.Thirdly,the paper enriches the research on the mediating mechanism of transactive memory system on team performance,i.e.,exploratory learning and exploitative learning are introduced as mediating variables between transactive memory system and team performance,and the mediating effects of the two kinds of learning are verified by data analysis.The conclusion of the study helps managers to fully realize the important role of team members'differentiated expertise in team performance.When forming a team,managers should fully consider the cognitive structure of the whole team and pay attention to the positive role of different learning styles.Finally,the application of ASW algorithm is generalized.The existing research on team faultlines mainly uses Fau_g algorithm to measure its strength.However,the drawback of Fau_g is that it only considers the situation of dividing the team into two sub-teams,which may be different from the actual team.ASW algorithm has the advantage of not restricting the number of sub-teams and is more universal,which helps to improve the reliability of research conclusions.
