Abstract The scale and required functionality of modern systems have increased and become more complicated. To successfully carry out the systems development projects, appropriate systems engineering (SE) and project management (PM) activities are required for the underlying process. In a system development organization, it is an effort to secure the SE & PM capability by adopting the CMMI is an evaluation model of improvement and ability of SE&PM process. To achieve the goal each organization establishes and uses its own organizational standard process, which satisfies the business characteristics. However, in practice, due to the lack of sufficient understanding on the interrelationship among different CMMI process areas, there still exist some difficulties with constructing organization processes. In systems development, the activities of SE are closely related with those of PM. Thus, the processes of SE and PM need to be fully integrated and explicitly linked to each other in order to complete the projects successfully. In this paper, we propose a SE&PM integration process architecture of organization that can be utilized in the system development organization is referenced in the construction of CMMI-based organizational process. Key Words : CMMI, Systems Engineering, SEPM, Process Architecture 1. 서론 현대시스템의규모와요구기능및인터페이스가대형화, 복잡화됨에따라연구개발조직에서는시스템공학 (SE) 과프로젝트관리 (PM) 역량이중요하게요구되고있으며시스템공학과프로젝트관리에관한국제표준에서도시스템개발활동에있어서의체계적인 SE&PM 활동을정의하고있다 [1,2,3]. * Corresponding Author : Jae-Chon Lee (Ajou Univ.)

2 한국산학기술학회논문지제 16 권제 6 호, 년미국카네기멜론대학부설연구소 (CMU/SEI) 에서는시스템개발조직의프로세스개선및능력성숙도평가모델인 CMMI(Capability Maturity Model Integration) 를개발하였으며, 전세계적으로많은조직에서 CMMI 를도입하여적용하고있다. CMMI는조직의능력성숙도를레벨1 부터레벨5 의 5단계로표현하고있으며, 레벨 2는프로젝트관리에초점을두고있으며레벨3에서는시스템엔지니어링에초점을두고있다 [4]. 아울러방위사업청에서는무기체계연구개발사업수행시체계공학적용을방위사업관리규정에서의무화하고있으며, 2012년에 CMMI 레벨2&3 요건을반영한연구개발사업의체계공학 (SE) 기반기술관리업무실무지침서를개발하여시스템공학기반시스템개발및프로젝트관리를강조하고있다. 시스템개발조직에서는 CMMI 기준에부합하는조직의표준프로세스를구축하고프로세스내재화를위한노력을하고있으나조직의규모 (Small Size), 소요비용 (Effort), 비즈니스특성, 기대효과등의이유로어려움이따르는건사실이다 [5,6]. SE와 PM은시스템개발활동에있어서상호밀접하게연관되어있으며일부업무는시스템공학활동과프로젝트모니터링및통제영역인두영역에서공통적으로포함하고있다 [7]. 따라서개발조직에서시스템개발표준프로세스를구축할때는 SE와 PM 프로세스가상호통합되고연계성이확보될수있도록구축되어야한다. 하지만 CMMI 프로세스영역간연관성과중복성등의구조적특성으로인해조직에서 CMMI 적용의어려움을겪고있으며, 이를해소하기위해해당조직에서시스템공학활동과프로젝트관리역량을자체평가하고지속적인개선활동에유용한참조기준이연구되어제시되었다 [8]. 조직의최상위수준에서프로세스지침을정의하고있는품질경영시스템국제표준인 ISO9001을인정받은조직이연구개발프로세스개선과프로세스능력성숙도인증을확보하기위해 CMMI 모델도입을시도하고있다. 이를위해기존 ISO9001기반프로세스와 CMMI 프로세스요건을상호매핑분석을통해통합된프로세스요건을제시한연구가수행되었으나연구결과가조직에서제대로이해되어성공적으로조직에접근하기위해서는조직의표준프로세스를구축하기위한상위수준에서의프로세스아키텍처가제시가필요하다고판단한다 [9,10]. 본논문에서는조직에서 CMMI 기반조직의 SE&PM 표준프로세스구축에참조되고활용될수있는조직의 SE&PM 통합프로세스아키텍처를제시하며, 본논문의구성은제1 장에서는서론을기술하고제2 장에서는 SE&PM 통합프로세스아키텍처의필요성을식별하기위해 CMMI에서 SE와 PM 프로세스를분석하고 SE와 PM의연관성을분석하였다. 제3장에서는개발된 SE&PM 통합프로세스아키텍처를제시하였으며, 제4장에서는구축된 SE&PM 통합프로세스아키텍처를바탕으로조직의표준프로세스구축사례를기술하고마지막제5장에는결론을기술하였다. 2. SE&PM 통합프로세스아키텍처필요성 2.1 CMMI에서의 SE&PM 프로세스분석 CMMI는 5단계 (Level) 의조직능력성숙도단계로구분하며조직프로세스관리 (Organization Process) 범주, 프로젝트관리 (Project Management) 범주, 엔지니어링 (Engineering) 범주, 지원 (Support) 범주등 4개의프로세스범주로나누어전체 22개의프로세스영역으로구성되어있다. 레벨1 의특징은프로세스가정의되지않고 Ad hoc Process 상태이고, 레벨2 는프로젝트차원에서프로세스가정의되어수행되고있으며프로젝트관리프로세스에초점을두고있다. 레벨3는조직표준프로세스가정의되며시스템엔지니어링프로세스에초점을두고있고, 레벨4와레벨5는조직의비즈니스및프로세스성과관리와지속적인프로세스개선활동에초점을두고있다. 레벨2 에서레벨5 까지전체 22개의프로세스영역중에서 18개프로세스가레벨2와레벨3에포함되어있으며대부분이프로젝트관리 (PM) 와지원 (SUP) 범주, 그리고엔지니어링 (ENG) 범주에해당된다 [4]. Fig. 1. 의 CMMI Institute의심사통계보고서에의하면 2014년수행한전체 1628 조직중에서레벨3 심사 ( 레벨2 요건을포함함 ) 를받은조직이전체 73% 이상으로서가장많다 [11]. 이는 CMMI 성숙도단계의프로세스중에서시스템개발활동과제품의품질에직접적인영향을주는성숙도단계의프로세스가레벨2와레벨3 의프로젝트관리, 엔지니어링, 지원프로세스범주의프로세스들이라는것으로해석할수있다. 즉고객이요구 4138

3 CMMI 기반시스템공학과프로젝트관리통합프로세스아키텍처개발 하는제품을개발하고품질을향상하기위해서개발조직이필수적으로 SE&PM 역량을제고하여야하며, 이를위해서는조직에서는 SE&PM 표준프로세스가구축되어프로세스에의한체계적인개발활동이수행되어야한다는것이다. 공통적으로포함하며상호밀접하게연계되어있다 [7]. Table 1.

Fig. 2. 와같이프로젝트관리는시스템공학활동과프로젝트모니터링및통제영역으로분류되며범위정의, 리스크관리, 고객과의상호작용업무는시스템공학활동과프로젝트모니터링및통제영역인두영역에서 Fig. 2. Relationship between SE and PM [7] 2.3 SE&PM 통합프로세스아키텍처필요성 시스템개발조직이 SE&PM 역량을확보하기위해서는조직의표준프로세스 (Process), 교육받은사람 (Skilled People), 그리고도구와기법 (Tools & Method), 이 3가지요소가상호유기적으로통합되고관리되어야한다. 그중가장중요하다고판단되는조직의표준프로세스는 SE와 PM 프로세스간상호연계성이확보되어야만효과적이고효율적인프로세스가될수있을것이다. 이를위해서는먼저프로세스의아키텍처를작성해서프로세스의완전성과프로세스간의연계성검증이필요하다. 하지만개발조직현장에서는 CMMI 프로세스영역간연관성과중복성등의구조적특성의어려움으로인해조직표준프로세스의완전성과프로세스간연계성이미흡하며이는프로젝트에프로세스이행과조직전반에걸친실질적인프로세스내재화의장애요소가되고있다. 본논문에서는 CMMI기반에의한프로세스개선및내재화를통해 SE&PM 역량을제고하고제품의품질을향상하기위해필수적으로요구되는 CMMI 레벨2와레벨3의 SE&PM 통합프로세스아키텍처를제안하고자한다. 3.

CMMI SE와 PM 프로세스식별은시스템개발활동에직접적으로관계있는 CMMI Project Management, Engineering, Support 범주의레벨2와레벨3의 15개프로세스영역에제한을두었으며, 프로세스영역별주요수행활동과작업산출물을 Fig.3. 과같이식별하였다. 두번째는 CMMI 프로세스간연계성을파악하고수행활동 (SP) 간의중복성을 Fig. 4. 와같이파악하였다. 중복성이라는의미는시스템개발조직에서 CMMI기반 SE 와 PM 조직표준프로세스를구축함에있어서서로유사한활동으로통합이요구된다는의미이다. 프로젝트계획수립에대한활동은프로젝트계획수립 (PP) 과통합프로젝트관리 (IPM) 프로세스영역에서일부수행활동이중복되어설명되고있다. 프로젝트모니터링활동은프로젝트모니터링 / 통제 (PMC), 통합프로젝트관리 (IPM) 프로세스영역에서일부수행활동이중복되어있고위험관리활동은프로젝트계획수립 (PP), 프로젝트 모니터링 / 통제 (PMC), 위험관리 (RSKM) 프로세스영역에서중복성이나타나고있다. 그리고의사결정및문제해결활동은기술적솔루션 (TS) 과의사결정분석 / 해결 (DAR) 프로세스영역에서중복되어있음을발견하였다. 세번째는 CMMI 프로세스수행활동간중복성을제거한 SE&PM 통합프로세스영역을도출하였다. 프로젝트관리프로세스영역은 CMMI의프로세스영역의중복된내용을제거하고프로세스영역을통합하였으며, 엔지니어링프로세스는 CMMI 프로세스영역 (RD, TS, PI, V&V) 을시스템개발수명주기단계관점으로프로세스영역을재정의하였다. 마지막으로통합된 SE와 PM 프로세스의입력과출력정보식별을통해프로세스간연계성을분석하고 SE&PM 통합프로세스가 CMMI 레벨2와레벨3의 SE 와 PM 관련프로세스의커버리지를확보하고있음을확인하였다. 4140

5 CMMI 기반시스템공학과프로젝트관리통합프로세스아키텍처개발 Fig. 4. Identified Interrelationships of CMMI Specific Practices for Different Levels. 3.2 SEPM 통합프로세스아키텍처개발 3.1절에서 CMMI의 SE와 PM영역을분석하여 SE와 PM 프로세스를구성하는활동들을식별하였다. 기존의나눠져있던 SE, PM영역을통합하여프로세스로만들기위하여프로세스를구성하는활동들의입출력데이터흐름을바탕으로영역간의연계성을분석했다. Fig. 5. Derived Architecture Model for the Integrated Process of SE and PM 분석결과를바탕으로하여 Fig. 5. 와같이 SE&PM 통합프로세스아키텍처모델을생성하였다. SE&PM 통합프로세스를구성하는활동들과활동들간의연계성은모델을통해확인할수있다. 그러나실제시스템개발에통합프로세스를이용하기위해서는다양한관점의모델을통한분석이필요하다. 이를위해데이터관점에서분석을위한 N2 Diagram, 프로세스의흐름과활동들간의연계성을동시에분석할수있는 EFFBD(Enhanced Function Flow Diagram) 을활용하여 SE&PM 통합프로세스참조모델을생성하였다. Fig. 6. 은 SE&PM 통합프로세스의데이터측면에서의분석을위한 N2 Diagram모델링수행한것이다. N2 Diagram을통해서는두가지를파악할수있다. 먼저 SE와 PM영역내활동들간의데이터입출력관계를보여준다. 이를통해각영역내에서활동을수행하면서어떤산출물이나와야하는지, 이것들이다른활동들에어떻게영향을미치는지를확인할수있다. 두번째는 SE, PM 영역간의연계성을확인할수있다. 상호간의데이터교환을확인함으로써두영역이독립적으로수행되는것이아닌상호연계를이루며수행됨을확인할수있다. 이를통해실제시스템개발을수행하게될시활동들간의상호관계를미리파악함으로써프로젝트의지연을최소화하고문제발생시원인분석에활용할수가있다. Fig. 7. 은 SE&PM 통합프로세스를구성하는활동들의흐름과, 활동들간의상호연관관계를모두분석할수있는 EFFBD를활용한 SE&PM 통합프로세스모델이다. EFFBD는 SE&PM 통합프로세스아키텍처를구성하고있는활동들의흐름을파악할수있다. 활동들의선후관계, 특정시점이아닌수명주기전체에지속적으로수행해야할활동을한눈에파악할수있다. 이는실제조직에서시스템개발을수행하는과정에서프로세스를만들고자할때, 어느시점에어떤활동이수행되어야하는지를파악할수있어조직의프로세스를구축하는데기반이될수있다. 그리고활동들간의상호관계를확인할수있는데이것은데이터입출력을기반으로한분석결과이다. SE와 PM 프로세스에서특정시점에반드시도출되어야할산출물, 이것들이다른활동에어떻게활용되는지등을파악하여조직의프로세스를구축할때명확한업무분담및책임을할당할수있을것이다. 4141

Fig. 9. 과같이 3.2절에서제시한 SE&PM 통합프로세스아키텍처를기반으로도출된조직의표준프로세스는 CMMI 레벨 2&3의 SE와 PM 프로세스대부분의영역을포함한다는것을확인할수있다. 이는본논문에서제시한 SE&PM 통합프로세스아키텍처를기반으로조직의표준프로세스를도출하게되면 CMMI 레벨2&3의 SE와 PM 프로세스요건에부합되는프로세스구축이가능하다는것을의미한다. 따라서조직이 CMMI 기반에의한조직표준프로세스구축시본논문에서제시한 SE&PM 통합프로세스아키텍처모델이활용가능함을확인할수있다.

9 CMMI 기반시스템공학과프로젝트관리통합프로세스아키텍처개발 CMMI의 SE, PM 프로세스의복잡한연계성과프로세스영역간의일부프렉티스중복으로인해프로세스구축에어려움을겪고있다. 이로인해프로세스의개수가많아지고프로세스간의연계성미흡, 프로세스수행활동의중복등으로비효율적인프로세스가구축되어프로젝트의일정지연, 생산성저하등시스템개발활동에장애요소가된다. 본논문에서는 CMMI에서의 SE와 PM 프로세스의범위와관련성을분석후 SE&PM 프로세스통합을통해시스템개발조직에서프로세스구축에참조되고활용될수있는조직의 SE&PM 통합프로세스아키텍처를제안하였다. 제안된 SE&PM 통합프로세스아키텍처를활용하면효율적이고실용적 (Practical) 인조직프로세스구축이가능할것이며이는프로젝트참여조직간의역할과책임의명확화, 의사소통향상, 업무재작업감소등의정성적효과를가지고온다. SE&PM 통합프로세스아키텍처를참조하여구축한무기체계개발조직의표준프로세스는무기체계프로젝트의장기적인특성으로인해전체수명주기동안에서적용은하지못했다. 따라서 SE&PM 통합프로세스아키텍처를활용하여구축한조직표준프로세스적용의정량적효과검증은향후추가적인연구가필요하다.
