Prior research has emphasized the significant effect of service orientation on organizational performance. However, little research on service orientation has been conducted in the financial field, including the investment management service industry in which high quality service for clients is required. In this paper, we propose a research model that centers on the concept of service orientation as a type of dynamic capability affecting firm performance. The research variables include job competency, risk management capability, operational capability, service orientation, and service performance. We assume that service orientation partially mediates the effects of risk management capability and operational capability on service performance. To test the model, we collected data from 391 fund managers in 86 teams (37 investment management companies) and analyzed it with partial least squares (PLS) method. Each of the 391 fund managers was asked to answer team level measures, which is effective for team level analysis. We find that job competency positively affects both risk management capability and operational capability, which in turn affect service orientation. Risk management capability and operational capability are assumed to directly affect service performance. However, risk management capability does not influence perceived service performance, whereas operational capability does affect it. This result indicates that risk management capability does not directly affect service performance. However, via service orientation, considering that risk management inconveniences customers and is geared to enhance service orientation, service performance is positively affected. Operational capability does not influence service orientation, whereas it affects perceived service performance. This result reveals that operational capability directly affects firm performance. As expected, service orientation significantly affects the service performance perception of fund managers. This study contributes to the literature by introducing service orientation to the financial industry and measures and tests team-level service performance. Our findings also provide insights to practitioners because to enhance team performance, managers must focus on service orientation in addition to operational capability.

무기체계의 성능을 뜻하는 작전운용성능(Required Operational Capability)은 신규 무기체계의 소요 결정 시 함께 결정되며, 무기체계의 획득부터 전술적인 운용에 이르기까지 결정적인 영향을 미치기 때문에 이를 정의하는 것은 매우 중요한 일이다. 본 연구에서는 새롭게 개발되는 무기체계인 관측포탄의 ROC를 검증하기 위한 시뮬레이션 기반의 방법론을 제안한다. 이를 위해, ROC를 구성하는 무기체계의 주요 성능과 무기체계의 성능에 영향을 미치는 외부환경요인을 입력값으로 하고, 작전운용효과를 결과값으로 출력하는 이산사건 시뮬레이션 모델을 제안한다. 시뮬레이션 모델을 구현하는데 필요한 모의논리를 설명하고 민감도 분석 등 다양한 시뮬레이션 결과를 활용하여 ROC를 검증할 수 있는 방법에 대해 설명한다. 본 연구는 관측포탄과 같이 유사무기체계가 없고 군의 분석모델을 직접적으로 활용하기 어려운 무기체계의 ROC를 분석하고 작전효과를 예측할 수 있는 방법론으로 활용이 가능할 것이다.

The most important task in acquiring the weapon system is to determine the required performance and to test & evaluate it. The importance of the weapon system by ROC (Required Operational Capability) is not considered, and system development and test evaluation are carried out. In addition, technical incidental performance is tested on the same basis as ROC in the test evaluation and determined according to the result. Development test and evaluation that evaluates technical ability is very important, but development agency is supervised and performed. In this paper, we propose a method to give weights considering the importance of ROC, a technical incidental performance determination and test procedure, and a improvement plan for the development and operational test & evaluation.

최근 70여 년간의 주요 전쟁을 통해 본 무기체계의 핵심적 변화중 하나는 IT 활용을 통한 무기체계의 복합화 및 첨단화라 할 수 있다. 이러한 무기체계의 복합화 및 첨단화 추세는 IT의 효과적인 활용, 전력화 기간 단축, 복합 첨단 무기체계에 대한 명확한 운용개념(Operational Concept) 수립, 작전요구성능(ROC : Required Operational Capability) 관리 등을 포함하여 무기체계 개발 절차 전반에 대한 혁신적인 개선을 요구하고 있다. 특히, 새로운 무기체계에 대한 명확한 운용개념 수렴과 이를 근간으로 도출된 작전요구성능에 대한 체계적인 관리는 '저비용 고효율'의 무기체계 개발, 나아가 성공적인 군사력 건설을 위한 핵심 선결 과제라 할 수 있다. 본 논문에서는 한국군의 현 작전요구성능 관리절차 분석을 통해 요구공학 (Requirements Engineering) 개념에서의 요구사항 도출(Elicitation) 및 분석(Analysis)과 요구사항 확인(Validation)측면을 고려한 개선 방안을 제안 한다.

Remote-controlled and autonomous driving based on artificial intelligence are key elements required for unmanned combat vehicles. The required capability of such an unmanned combat vehicle should be expressed in reasonable required operational capability(ROC). To this end, in this paper, the requirements of an unmanned combat vehicle operated under a manned-unmanned teaming were analyzed. The functional requirements are remote operation and control, communication, sensor-based situational awareness, field environment recognition, autonomous return, vehicle tracking, collision prevention, fault diagnosis, and simultaneous localization and mapping. Remote-controlled and autonomous driving of unmanned combat vehicles could be achieved through the combination of these functional requirements. It is expected that the requirement analysis results presented in this study will be utilized to satisfy the military operational concept and provide reasonable technical indicators in the system development stage.

The Korean medical evacuation helicopter was developed based on the Korean Utility Helicopter (hereafter referred to as 'Surion'). It uses an auxiliary power unit and engine for heating during winter operation. The helicopter maintains the internal temperature of the aircraft using its bleed air to satisfy its operational capability. However, due to the air inflow through the gap between the aircraft skin and door, additional heating for operating the portable medical equipment and preventing hypothermia in evacuated patients is required. Accordingly, an electric auxiliary heater was developed for additional heating during winter operation, and environmental, durability, and performance tests were conducted per MIL-STD-810G and MIL-STD-461F. The auxiliary heater was verified per the tailored airworthiness certification criteria.

Today's world is generation of Transformation. The Term "Transformation" is widely used in many nations and international organizations such as U.S. and NATO to describe the course of change undertaken by militaries to respond to the new and emerging security environment. Transformation involves all elements of the defense enterprise including Operational Environment, Operational Concepts, Doctrine, Structure and Technologies, within a supportive Cultures context. An Operational Environment is defined as "a composite of conditions, circumstances, and influences that affect the employment of military forces and bear on the decisions of the unit commander." The context for developing future military concept and capability lies essentially within the anticipated boundaries of the operational environment in a collective sense. The joint operational environment is essential to the nation's defense. It describes volatile, complex, and dangerous environment in which the military personnel. organizations, and material will operate. Implications coming forth from joint Operational Environment are but a starting point - many others exist. More and better Implications will come forth as people think about massages of Operational Environment, experiment its characteristics, learn to deal with its threats and scenarios, apply their experience and judgement, and then consider what is required of Korean military doctrine, organizations, training and education, material development, and leadership for operations in the joint Operational Environment.
