So, how to improve the quality and reliability of decision-making seems very necessary. Starting from the Prospect Theory of behavioral decision-making theory, this paper puts forward testing decision-making behaviors of Top Management Team, and analyzes the specific process and methods of decision-making. According to results of the decisionmaking behavior testing, the characteristics of Top Management Team can be obtained, and so as to provide reasonable foundation for evaluation and improvement of decision-making behaviors. Keywords - Behavior testing, decision-making behavior , decision simulation, top management team I. INTRODUCTION The Nobel Prize Winner Herbert Simon used to say that “management is making decision”, which reveals how important the decision-making is in business administration. With the global economic integration goes further in China, drastic market competition and rapid changes of information revolution, diversification oriented business and close coordination oriented department all present new challenges to executive leaders[1]. At the same time, team decision-making gradually takes place of personal decision-making and is becoming more and more important in business administration. By full understanding of Top Management Team (TMT) on decision–making behavior characteristics, we can make better use of the advantages of certain teams and achieve the effect that team decision is superior to individual decision, thus we can keep continual development of business in the long run. Katzenbach defined TMT as “top leaders team in organizations and institutions”, they usually have the power to solve problems, coordinate activities, mobilize organization members and make important decisions of the company. Because of the importance of the TMT, researchers in both domestic and overseas do a lot of ____________________ This work was partly supported by the National Science Foundation of China (Project No. 71171043), the National Basic Scientific Research Expenses - National Project Breeding Fund (Project No. N090406006) and the National Undergraduates Innovating Experimentation Project “Under Team Task Situations Decision-Making Behavior of Business Executives Test Platform” (Project No. 110105). researches on behaviors of TMT. Henning Bang and his partners got the conclusion that goal clarity and focused communication is positively related to team effectiveness by self-report and observer data from eight top management groups that processed 56 agenda items during meetings, thus provided instructions on how to make decisions efficiently. At the same time, they extended three dimensions related to team efficiency: task performance, relationship quality, and member satisfaction [2]. From two total different aspects: functional-background and locus-of-control, Chirstophe Boone and Walter Hendrisks analyzed the compositional diversity and organizational performance by collecting and analyzing the data collected from scientific and technical corporations, and they finally provided instructions on the optimizing of team composition [3]. In this paper, we introduce decision simulation system into the research of decision-making test of TMT, so we can avoid the problems that are met in traditional surveys, such as information distortion and data ambiguous. This paper also takes advantage of management simulation programs to create management decision scenarios which are very similar with real market. By data collection and result analyzing, we can obtain decision-making characteristics of TMT, and finally help TMT to improve their decision performances. II. METHOD A. Behavioral decision-making effect Behavioral decision-making theory is a new theory developed to solve problems that are difficult to rational decision-making theory; classical decision theory also can be regarded as special case of behavioral decision-making theory when there are a lot of hypotheses. In 1979, Kahneman and Tversky (KT) put forward the Prospect Theory under uncertain conditions of personal decision behavior based on economic experiments[4], thus denied the Expected Utility Maximization Theory proposed by Van Newman and Morgenstern in 1944 [5]. Expected Utility Maximization Theory holds the opinion that the preference of a decision maker is changeless, and his decisions can be predicted by statistical methods. On the contrary, Prospect Theory indicates that there exists Framing Effect, Reference Point Effect, Deterministic Effect and other effects caused by irrational behaviors under uncertain conditions, what’s more these irrational behaviors make individual decisions betray the Expected Utility Maximization. Framing Effect manifests that different formulations can lead to different preferences to the same problem. Deterministic Effect manifests that decision makers have obvious preference on certainty. In fact, these two effects are both caused by the changing of reference point which has a big influence on individual decisions. In different fields, different environments and among different individuals, decision makers’ reference points may change, and we define this change as Reference Point Effect. For example, through experiments Zhan-lei Li validated that there exist Framing Effect, Reference Point Effect and Deterministic Effect in individual decisions under the environment of economy, society and culture [6]. In view of different behavioral decision-making effects’ different influences, in this paper we mainly use four effects (Reference Point Effect, Framing Effect, Fuzzy Avoid Effect and Deterministic Effect), which are extended from Prospect Theory, to test decision behaviors of TMT under different decision scenarios and analyze their behaviors’ characteristics. B. Management simulation Management Simulation is a kind of Computer simulation system using Computer Science, Management, Game Theory and Operational Research, and it is used to simulate management activities of business. The earliest Management Simulation came from some of American famous universities in 1850s, and the first university to use it was the University of Washington. In 1957, the University of Washington used a simulation system named High-level decision-making and management in the course of Business guidelines [7]. According to the data of 2001, more than half of the core members belonging to the Association to Advance Collegiate Schools of Business (AACSB) widely use Management Simulation in such courses as Strategic Management, Marketing, Accounting and Finance, and there are also Management Simulation Competitions in America and some other regions. At present, there are mainly 3 kinds of Management Simulation in the world, these are Management Game governed by Carnegie Melton University (CMU), MBABEST21 governed by CSIM College of Aoyama Gakuin University and Global Management Challenge [8]. When taking part in these Management Simulation systems, corporate executives will form several teams. These teams compete with each other and try to improve their own business’s performance. As a result, they can experience management, use theory and cultivate innovative thinking [9]. Aiming at testing subsjects’ decision-making behaviors, this system takes advantage of parameter model used in traditional Management Simulation systems when design testing scenarios. Besides, we create various kinds of testing scenarios based on four basic effects. At last, we can analyze their decision-making characteristics by the data we collected. C. Methods of decision-making testing From the middle of 1970s, behavioral decisionmaking had become an independent subject, and was widely used in areas of economy, finance and management. In this stage, research methods includes observational method, investigation method (mainly are questionnaire survey and interview survey) and experimental method (psychological experiment and economical experiment). Since then, these methods are also called general empirical research of decision-making behavior [10]. For example, by using “Asian disease problem”, Tversky and Kahneman testified the existing of Framing Effect and successfully questioned traditional invariance [11]. At present, researches of behavioral decision-making theory mainly focus on summarizing behavioral characteristics and refining the behavioral variables, then apply it to analysis of rational decision-making. Representative studies of this kind of researches include such four investor psychology models as BSV model [12], DHS model [13], HS model [14], BHS model [15], and Behavioral Asset Pricing Model [16], Behavioral Combination Model [17]. Being different with general research methods, this paper’s method uses logical processes to test TMT’s decision-making behavior under management simulation scenarios. That is testing decision makers’ behaviors and analyzing experiment results by controlling some variables under controlled experiment conditions, thus reinforce the reliability of the results. Besides, high emulation situation have directive functions in real life. III. SYSTEM DESIGN A. Overall structure of the system Aiming at testing decision-making behavioral characteristics of TMT, this system includes the function of managing multitask scenarios. There are two main subsystems: testing subsystem and analyzing subsystem. The overall structure of the system is shown in Fig. 1. As we can see, there are two modules in testing subsystem which are module of testing online and module of information services, and two modules in analyses system: module of data statistics and module of management of testing scenarios. At first, subsjects log in. Secondly, they should input their team information and then they can choose testing scenarios. After all of these, they will enter into testing subsystem to finish the whole processes under the guide of the system. B. Design of database Database is used for depositing testing data of testing subsystem and system parameters of simulation programs. Login Subjects Manager Testing online Data Statistic Database Information services IV. SYSTEM IMPLEMENTATION Based on decision-making testing scenarios and researches of four effects, variable testing scenarios can be designed to cater for different demands of subjects. According to different testing scenarios and relevant parameters this system can provide special decisionmaking situation for subjects. There are mainly four functional modules in this system: situation management, testing online, data statistic analysis and information services. A. Situation management Management of testing situation Fig. 1 Overall structure of decision-making behavior testing In testing phrases, subjects input decision variables and decision values as the simulation system asked. Then, the system will use relevant decision parameters that are set by managers in advance to calculate the results of simulation operation. Finally, the results will be seen in the interface as the form of reports; in decision-making behaviors analyzing phrase, managers take advantages of statistic analysis software to analyze all the decision data and give the results of the subjects’ characteristics of decision-making behaviors. C. Design of function module This system obtains results of decision-making testing and of behavioral testing by calculating various of function modules, which includes module of parameter setting, module of operation calculating and modules of decision behavior analyzing. Among these modules, module of parameter setting is used for creating decision simulation environment and reducing errors to real situation; module of operation calculating, which includes demand function, constant cost function, variable function and so on, is used for calculating the operational results based on the values inputted by subjects; module of decision behavior analyzing is used for analyzing the decision data and the results of operation, and finally the testing results by classifying subjects’ behaviors based on four effects mentioned before can be obtained. This function includes adding testing scenarios that have been designed, modifying relevant marketing parameters in every progress according to different behavioral decision-making effects, editing or deleting certain situations that are not significance in testing phrase. Only managers have the right to modify parameters to cater for demands. B. Testing online Testing online mainly provides functions that can be used to test subjects’ decision-making behaviors. At first, subjects log in main interface, then under the guide of the system they can implement testing needed. This system provides individual settings, which are single-period testing and multiple rounds of simulations decision testing, in view of different testing aims. In single-period testing, system will guide subjects to another decision situation after they finished their first decision-making and provide simulation operation results. Subjects will be tested a lot of times under certain testing scenarios, where only some certain parameters will be changed in order to control certainty of simulation situation, until enough data has been collected. In multiple rounds of simulations decision testing, subjects will be required to manage a company for several periods and testing scenarios will be changed along with subjects’ decisions. And different with single-period testing, subjects’ decisions will always affect next period in multiple rounds of simulations decision testing. directions on the composition of TMT according to their different decision-making behavioral characteristics. Login main interface User Information services Yes Other operations No Select criteria Searching criteria Whether do further searching Getting the result Fig. 2. Process of searching C. Data statistic analysis After all the tests are over, managers will use statistical analysis software to analyze data which subjects submitted, and final results will be obtained. D. Information services There are mainly two aspects: in multiple rounds of simulations decision testing, operational results will be provided and can be searched; after tests over, decisionmaking behavioral characteristics and relevant suggestions will be provided. The process of searching is showed in Fig. 2. V. SUMMARY The trend of economic globalization has brought great challenges to companies, so how to ensure the quality of executives in decision-making will become increasingly important. Decision simulation system, which integrates application of management science, decision science, computer technology and IT, can provide managers with a realistic management environment and good experimental environment for researches on decision-making behaviors. Based on the four behavioral decision-making effects of prospect theory, we develop a testing system to test executives’ decision-making behaviors. Using this system, TMT can obtain their different decision-making preferences under the conditions of uncertainty and understand their own decision-making behavior characteristics. Thus, they can avoid decision-making bias in a major decision and improve their decision-making as a whole quality.
