14 SCM 정의 SCM is about the flow of products and services and
the associated information, across the whole business system to maximize value to the end customer. Managing the integration of supply chain elements through the design and integration of physical infrastructures as well as the supporting systems, processes, and organizational structures.

15 SCM의 등장 배경  기업의 전문화에 따른 핵심 역량 경영의 지향  기업의 전문화로 인하여 기능간의 제휴와 규모의
이점이 발휘되어 어려운 문제가 발생  분업화, 전문화의 장점을 취하면서 고객 만족의 실현과 최고의 생산성을 추구 할 수 있는 기업간 프로세스의 통합화가 필요  정보기술(IT)의 발달과 물류 인프라 및 아웃소싱 전문업자의 성장

16 SCM의 필요성  고속 경영, 캐시 플로우 경영의 필요성 대두  경영상의 현금 회전율을 증가시키려면 재고의 대폭
감소, 비즈니스 리드타임의 단축이 필요하며 이를 실현하는 메커니즘이 SCM이다.  비용의 획기적인 삭감의 필요성  다이렉트 판매 구조를 통한 간접 비용의 삭감  모듈화, 글로벌 아웃소싱, TOC(제약이론)적 접근에 의한 직접비용의 삭감  고객 만족의 극대화 필요성  고객과 직결된 supply chain 구축을 통하여 완벽한 만족감을 공급하는 구조 창출

17  부가가치(Value Added)의 발생 :
 제조(30-40 %) , 기타 Chains(60-70 %)  과잉 재고 보유 :  불확실성 대비(고객 수요, 공급자 Delivery)  IT(Information Technology)의 발전  Network, EDI, Internet/WEB/Extranet, EC, ERP

22 Proprietary information is shared.
In Supply Chain Relationships Proprietary information is shared. Assets are invested in joint projects. Joint improvements are pursued. Risks and benefits are shared.

24 Total Cost of Ownership
100% Total cost of ownership = 100% 20% End user’s maintenance 80% 16% OEM warranty costs 7% Transportation costs 60% 13% Holding costs Cost Price + Internal Support = 90% 40% 5% Purchasing costs Purchase price 8% Supplier profit margin 20% 21% The percentages on this slide are used only as an example and are not based on actual figures. Material costs 0% Integrated Circuits Adapted: C.D. Ittner and L. P. Carr, “Measuring the Cost of Ownership,” Journal of Cost Management (Fall 1992).

25 Process Reference Model
Process reference models integrate the well-known concepts of business process reengineering, benchmarking, and process measurement into a cross-functional framework. Quantify the operational performance of similar companies and establish internal targets based on “best-in- class” results Benchmarking Characterize the management practices and software solutions that result in “best- in-class” performance Best Practices Analysis Process Reference Model Capture the “as-is” state of a process and derive the desired “to-be” future state Business Process Reengineering Capture the “as-is” state of a process and derive the desired “to-be” future state Quantify the operational performance of similar companies and establish internal targets based on “best-in-class” results Characterize the management practices and software solutions that result in “best-in- class” performance Source: Slide presentation from Supply Chain Council, Inc, Stevens, Scott, “Supply Chain Operations Reference (SCOR) Model Overview.” Original Source: 1997 PRTM ISC Benchmark Study
