Software Process Improvement(SPI) has been a challenging issue to software organizations. The factors affecting SPI were analysed for improving software development processes. Numerous studies suggested influencing factors, and assessment models were utilized for software improvement. This research suggested that SPI factors affecting on an organizational performance may vary according to the CMM(Capability Maturity Model) level. The moderating effects of organizational maturity level between the SPI factors and the organizational performance were empirically tested. This research found that all six SPI factors except for the resistance to change affected the organizational performance. The moderating effects of management support, goal alliances, participation, and effect analyses were empirically supported. These results can provide several implications or a practical guidance to academic and industry professionals.

The international SPICE (Software Process Improvement and Capability determination) Project ISO/IEC 15504(SPICE : Software Process Improvement and Capability determination) is an emerging International Standard on SPA(Software Process Assessment). A prime motivation for developing this standard has been the perceived need for an internationally recognized software process assessment framework that pulls together the existing public and proprietary models and methods. A SPICE assessment can be considered as one of representative SPA model since assessors assign ratings to indicators and metrics to measure the capability of software process. But this models doesn't provide a systematic measurement procedures and dynamic method for SPI(Software Process Improvement). Through the evaluation of SPICE is capable of providing a substantiated basis for using the notion of capability, as well as providing information for nacessary improvements to the standard using 6sigma process. As a result, this paper propose a measurement procedure and guidelines for application of 6sigma process to guarantee the reliability in SPI and suggest the structure to support SPI on overall organization.

SPI (Software Process Improvement) activities have been considered one of the crucial approaches to achieve high quality, productivity and timely delivery of software products and services. The basic premise of SPI model is that higher maturity levels lead to better performance. In this research, the relationships between SPI results and performance were empirically investigated with Korean software companies. CMM key process areas were categorized into two dimensions, "Process Implementation" and "Quantitative Management". The relationship between process implementation and performance was significant, but the relationship between quantitative management and performance was insignificant. The control variable, size of OU(Organizational Unit), did not have significant impact on the relationships between SPI activities and OU performance.

Software companies try to upgrade the level of technology and quality of their products by adopting Software Process Improvement (SPI). First of all, the companies must understand affecting factors based on various environmental view points in order to acquire competitive advantage. In this study, a research model gets started on the basis of literature reviews, and identifies SPI factors that affect the maturity levels of organizations. Organizational members and assessment types are chosen as moderating factors. An empirical research has been made for analyzing the causal relationships among affecting factors and CMM levels. The results of this study will suggest several implications to decision makers who handle SPI issues.

Software Process Improvement(SPI) becomes an important issue at software quality. A research model is suggested on the basis of previous literature. The model includes success factors for SPI as independent variables and CMM levels as mediating variables, and defines organizational performance as dependent variables. This study basically investigates causational relationships among SPI success factors, CMM levels, and organizational performance through a structured equation model. A LISREL v8.72 for windows is used for statistical analysis. Even through success factors for SPI partially influences the CMM level, the CMM level is fully related to the level of organizational performance. The results show that the success factor for SPI in Korean companies are not equal to the factors abroad, but indicate that the CMM level is closely related to the organizational performance. These results will be helpful to academicians as well as to practitioners.

소프트웨어 개발 성숙도를 향상시키기 위한 프로세스 프레임워크로써 IS 15504(SPICE) 및 CMMI 등은 이미 검증된 모델이다. 하지만 이들 프로세스 성숙도 모델들이 기업의 개발능력 및 효율을 높여주는 구체적인 실천방법을 제시하지는 않는다. 기업 내에서의 실제적인 적용을 위해서는 위의 모델들을 기반으로 제품이나 기술 도메인, 사업 및 조직의 규모 등 기업환경이 고려된 기업 고유의 모델의 개발 및 적용이 필요하다. 본 논문에서는 소프트웨어 개발 프로세스에 대한 수년 간의 지속적인 적용 및 개선 경험을 바탕으로 기존의 SPI(Software Process Improvement) 모델을 확장하여 기업의 비즈니스 목적과 환경에 부합하도록 조직차원의 전반적인 소프트웨어 개발 경쟁력을 강화한 사례를 소개한다. 기존의 SPI 모델이 프로세스 각 분야에 대한 정의와 성숙도를 판단하기 위한 능력 수준을 정의한 것에 비해 본 논문에서는 그 영역을 핵심기술 및 조직구조까지 확대하고, 능력 수준을 일반적인 프로세스 능력 수준이 아닌 조직에서의 모델의 확산도로 확장하여 소프트웨어 개발 경쟁력을 강화하기 위한 통합된 모델을 정의하여 적용하였다. 본 논문은 기업에서 확장된 프로세스 성숙도 모델을 이용하여 조직의 능력을 향상시키는 구체적인 사례로 유사 영역에서 참조 모델로 활용될 수 있을 것이며, 프로세스 성숙도 모델 연구에 대한 기업의 피드백으로의 기여가 있을 것이다.

최근의 소프트웨어 시장에는 조직의 사업 목적 달성을 위한 성숙모델, 표준, 방법론 및 지침들이 개발되고 있다. ISO/IEC 15504와 CMMI등 모든 SPI 모델들은 숙련된 전문 심사원을 통하여 소프트웨어 프로세스의 능력수준을 결정한다. 그러나 숙련된 전문심사원이라 할지라도 프로세스 측정을 위한 체계적인 척도를 제공하지 않으므로 심사원은 심사대상 프로세스의 정량적인 수준 측정을 위하여 객관적이며 일치된 판단을 통해 프로세스를 평가할 수 없다. 본 논문에서는 ISO/IEC 15504와 CMMI의 핵심 프로세스들에 대하여 정량적이고 객관적인 측정을 위하여 척도를 설계하였고, 실험을 통하여 척도의 타당성을 분석방법을 이용하여 증명하였다. 이를 통해 객관적인 측정 절차와 척도의 사용을 통하여 효과적 SPI 활동을 기대할 수 있다.

The analysis on the relationships among SPI models and restructuring SPI models according to a common framework makes it possible to compare and integrate the numerous research results about the models. It also makes it possible to assess objectively and accurately the results and benefits of evaluating an organization which has been evaluated according to a partial SPI model according to a new and integrated SPI model.
