Development of the training method for improving team performance of dispatchers Masamichi KATO, Shinichi AONUMA, Hiromi SHIZUYAMA, Ken KUSUKAMI Safety Research Laboratory, Research and Development Center of JR East Group East Japan Railway Company The general role of the traffic control centers in the railway system is to manage the railway traffic as a whole through controlling train operation on the lines in their areas of responsibility. To accomplish the role, the centers are strongly expected to handle unexpected troubles or accidents correctly, safely and quickly as crisis management centers in the railway. The dispatchers in the center are, therefore, required to show and maintain high performance in emergency situations. An effective approach to raise their ability is to improve team performance between dispatchers, in addition to improve individual ability. This type of training is already common in the industries in which higher safety levels is required, for example, flight crews in airlines and operators in nuclear power plants. East Japan Railway Company has developed and introduced a training method for improving team performance of train dispatchers (JR version of CRM). In this paper, the aim, concept and contents of this method are outlined. 1. Introduction of Tokyo Control Operation Center JR East operates more than 12,000 trains per day, and carries 16 million passengers. On the busiest lines in the Tokyo metropolitan area, trains run every two minutes to transport a large number of passengers. The important roles of railway dispatchers are to assure safe and punctual transportation by collecting necessary information for railway operation, making quick and appropriate judgment, giving accurate instructions and information, and supporting actions by operators, such as drivers, conductors, and station staff. The Tokyo Control Operation Center where JR version of CRM was developed controls trains in the Tokyo metropolitan area. Here, railway transport dispatchers manage daily traffic operations and, once any trouble occurs, they play a main role in reorganizing the schedule by changing the operational plan. Railway transport dispatcher teams are composed of leaders (chief dispatchers), planners, system controllers, system sub-controllers, and communicators. 2. Purpose of the Research An effective approach to raise the performance of the operation center is to improve team performance of dispatchers, in addition to improving their individual ability. Risk management ability is also required, since every kind of information about irregular or emergency situations is received by the operation center. The Safety Research Laboratory and Tokyo Control Operation Center developed a training method for improving team performance of dispatchers, 1 based on CRM (Crew Resource Management), which is conducted in airline companies as a team performance training method. We call it the JR version of CRM. The flow of this research and development is described below. 1. Analysis of problems in the work of the operation center 2. Comparison between work of airline pilots and that of railway dispatchers 3. Formulation of the concept of JR version of CRM 4. Development of teaching materials and tests of the training method The JR version of CRM was developed in 2003 and introduced in 2004 through basic education. 3. Analysis of problems in the work of the operation center First, we researched the present problems of the operation center. As a result, we found these four problems. (1) The goal image of the chief dispatcher is not clear There are operating manuals. But, what he should do in some situations depends on each chief dispatcher’s judgment. What he should be is not consistent among operation centers. (2) Criterion of success or failure is not clear The criterion for judging whether a dispatcher’s judgment is right or wrong is not clear, so that everyone tends to think it is natural for dispatchers to do this well every time. (3) People gather and disturb the communication between members. Once any trouble occurs, many dispatchers for lines that are operating normally gather to get information about the trouble. This group of dispatchers disturbs the communication between the members in charge of the line where the trouble has occurred (4) Method of education of newcomers is not formulated The work of dispatchers requires a lot of knowledge even from newcomers, but the method of education largely depends on each dispatcher. 4. Research of team performance training methods Next, we did research into team performance training methods, and found CRM (Crew Resource Management) as an effective method that is conducted in airline companies and has acquired an established reputation. CRM is based on the concept that every resource available should be used effectively to attain a safe and efficient flight. The word “Resource” includes human resources such as knowledge, experience, and skill of flight crews and dispatchers, and hardware resources such as information provided from outside through hardware systems. In the context of CRM as a training method, “Resource” refers mainly to effective use of human resources by the flight crew. The reason why airline companies pay attention to this concept can be summarized below. Even if airlines had introduced various kinds of safety devices and systems, and assigned severe training and qualification tests to flight crews, the number of accidents could not be reduced after 1970. Based on the analysis of flight accidents, NASA (Aeronautics and Space Administration) identified problems of team performance (details are described in the left side of Figure 1). The same kind of problem is also found in the results of the research by the railway operation center (shown on the right side of the 2 Figure). It can be said that the problems of flight crews and railway dispatchers have much in common. On the other hand, we find differences of job characteristics between flight crew and railway dispatchers. (1) A flight crew is basically composed of two members, a captain and a copilot, while teams in the operation center have about seven to fourteen dispatchers and the communication to station staff, drivers, and conductors is complicated. (2) In the airline, CRM is applied to technically fully-qualified pilots. On the other hand, a railway team often has a less experienced dispatcher who is acquiring knowledge and skill. (3) In CRM for pilots, problems in the flight are the principal subjects to discuss, while railway CRM has to cover the problems in usual situations, such as comprehension and trust between members, since dispatcher teams are generally formed by the combination of the dispatchers in charge of individual railway lines. Problems among railway dispatchers Problems in the flight crew Allocation of roles and responsibilities is not clear. Individual members cannot be fully controlled during trouble. Priority of work is not defined. Information does not spread to all the members. Important meters are not monitored cross-checked. Repetition of policy changes is caused by insufficient information. Trifling things absorb all attention. Some data are not used Prioritization is wrong because of poor distribution of attention. Policies are not shared. Emergency operations are delayed by improper risk management. Leadership is not taken. Figure 1 Comparison between flight crew and railway dispatchers in the problems of team performance 5. The concepts of JR version of CRM Next, we explain the four concepts of the JR version of CRM, identified by examination of the common and different features of cockpit crews and railway dispatchers. 5.1 Management cycle formed by the three phases of usual, emergency, and end of work Dispatcher’s work is composed of the sequence of usual and emergency operations. 3 The goal image of the chief dispatcher and the criterion of success or failure are not clear. In addition, dispatcher performance in emergencies is based on the performance in usual situations. We therefore think the following three points are important in forming the concepts of JR version of CRM. (1) We divide the dispatcher’s job into the three phases of usual, emergency, and end of work, and make the goal image of the dispatcher team in these phases clear. (2) We let dispatchers find that a good team condition in usual situations is closely linked with high performance in emergency. (3) We also let dispatchers understand the importance of the following process. After troubleshooting, the dispatcher team looks back at the actions they took and at the team coordination with respect to the standard, they identify lessons as a team, and this gives feedback to their usual work Through the above process, we can form the management cycle of usual, emergency, and end of work, and by going through this cycle, lessons are found and accumulated in the team, which makes the team performance continuously higher. We call it the CRM cycle (Figure 2). Reflect the lessons obtained by the analysis of the problems, and troubleshoot with the improved team performance Show the improved team performance Look back quickly and calmly CRM (debriefing) A cycle turns around Usual situation End of work Share problems, factors, and lessons Figure 2 CRM cycle 4 Identify and share the problems in the emergency situation, and seek the causes underlying the problems. Improve team performance and train each member, preparing for emergencies Emergency situation 5.2 Specification of goal image of chief dispatchers, other dispatchers, and dispatcher teams We specify the goal image of chief dispatchers, other dispatchers, and dispatcher teams to form the CRM cycle. Several images are for example described in Table 1 (emergency situation) and Table 2 (usual situation). Table 1 Examples of the goal image (emergency situation) # A chief dispatcher can always comprehend the situation as a whole. # A chief dispatcher can make the members completely understand his or her policy. # A chief dispatcher can appropriately give caution to the members in risky situations # A chief dispatcher can listen to the opinions of members objectively and neutrally. # A chief dispatcher and a deputy chief dispatcher can cover for each other in very busy situations. # Every member can share the information of the policy, present situation, etc. # A dispatcher other than the chief dispatcher can give necessary information to the members at the proper time. Table 2 Examples of the goal image (usual situation) # Members understand and accept the chief dispatcher’s policy and method. # Members often make proposals for work improvement. # Lessons and know-how are accumulated by looking back at cases. # Members understand the significance and importance of the dispatcher’s work. # Members accept other members, including the differences between others and themselves. # A chief dispatcher can teach and support inexperienced dispatchers. # A chief dispatcher can always communicate with chief dispatchers for other lines and with the general chief dispatcher. 5.3 Everyday training method Our training method is composed of two steps, basic education and everyday “debriefing”. Through the basic education, dispatchers are expected to understand the significance of improvement of team performance and the goal image of the dispatcher team, and learn the method of “debriefing”. Based on this, “debriefing” is held in every team every day. In the debriefing, team members look back and talk freely about the process and the method of the troubleshooting they handled on that day, by which they find and share the lessons. Debriefing was originally adopted in airlines, in which the crew reviews the flight and finds lessons through dialogue. The procedure of the debriefing is as follows. 1. Talk about which issues members should discuss 2. Decide on the issue 3. Identify the essence of the issue through dialogue 4. Decide the actions they should take after that 5 5.4 Establishment and progress of the basic conditions as a team We think that the two basic conditions described below are required to conduct CRM under the above three concepts. (1) Team members can talk about the problems of the team freely Trust between team members can be formed by free dialogue and discussion. Based on it, problems at the troubleshooting that chief or other dispatchers cannot find individually can be opened through dialogue, and the solutions can be discussed in the team. (2) A chief dispatcher can not only manage the team, but also teach and support the members It is important for chief dispatchers to give technical teaching and support to their members, rather than to only give necessary instructions in the work, since young or inexperienced dispatchers are always in the team. 6. Development of JR version of CRM We tested the “basic education” to develop the curriculum and the textbooks in accordance with the CRM concepts. As a result, we worked out three courses as basic education. These are for chief dispatchers, other dispatchers, and dispatcher teams. Details are as follows. (1) Educational course for chief dispatchers Chief dispatchers are expected to learn the basic knowledge and necessary skills for CRM, and management to raise the performance of the dispatcher team (2) Educational course for other dispatchers In this course, dispatchers are expected to recognize their own role in the team clearly and moreover to develop the ability to assist the members quickly and properly beyond their own roles in an emergency. (3) Educational course for dispatcher teams (Debriefing training) Chief and other dispatchers take this training together, in which the dispatcher team learns the objectives, significance and the method of debriefing, through experiencing it by themselves. In the test process of the basic education, we train “debriefing trainers”. Their role is to help the dispatcher team conduct debriefing appropriately according to the CRM concepts. On the other hand, all the problems discussed in the debriefing cannot be solved within the team. In order to solve them in the operation center as a whole and to share the solution, we organized the “larger CRM cycle” described in Figure 3. The CRM secretariat collects the problems which cannot be solved by the team alone, and works out solutions involving the upper level in the operation center. 6 Upper level in the operation center ・Leadership in CRM promotion ・Comprehension of the problem ・Implementation of the solution Provide Implement CRM secretariat ・Collect the problems found out in the debriefing ・Analyze the problems ・Feed the solution back to each team ・Send problems or proposals to the upper level Collect Provide Collect Provide D.F sheet Provide chief dispatchers for various areas Collect team debriefing team debriefing team debriefing Figure 3 Organizing the “larger CRM cycle” 7. Present CRM Tokyo Control Operation Center has introduced the JR version of CRM, taking three steps, since April 2004. In the first step that we call “Basic Education Step”, dispatchers learn the objective, concept, and method of CRM. In the second step called “Introduction Step”, debriefing is introduced in the real work for dispatchers to experience and understand the real CRM. In “Action Step” (the third step), the dispatcher team is expected to conduct debriefing without the assistance of debriefing trainers or the CRM secretariat. The teams of Tokyo Control Operation Center are now in this step. In more detail, each dispatcher team holds a debriefing about the troubleshooting they managed every day for around 30 minutes, using a “Debriefing Sheet” written by one of the members and “Management Sheet” by the chief dispatcher. Just after starting these debriefings, chief dispatchers were unsure about how to carry the debriefing forward. Other dispatchers also tended to hesitate to express their opinion. But, with the everyday repetition, dispatcher teams have gradually come to proceed with debriefing smoothly and to understand that appropriate debriefing achieves progress in team performance. Young or middle-experience dispatchers can talk frankly step by step, and find the significance and effect of talking freely in the team. We are now planning to spread the JR version of CRM to the other kinds of dispatchers who manage railway facilities such as tracks, structures, signals, and telecommunications. 7
