JIT란 무엇인가? 정의

JIT는 일본의 Toyota 자동차 조립공장에 있던 Taiichi Ohno에 의해 1970 년대 초기에 개척되었다. JIT는 제조업 조직의 철학이다.   JIT는 조립프로세스에서 부품을 필요로 할 때에만 부품을 공급하게 함으로써 낭비를 줄인다. JIT의 중심에 카드를 의미하는 일본어인 간반(Kanban)이 있다. 이러한 간반카드를 부품이 조립/제조 프로세스에서 소모될 때 창고에 보내 부품의 표준수량을 요청한다. JIT는 올바른 부품이 올바른 장소(조립라인의 작업대)에 적시에(just-in-time)에 보내져야 하므로 정밀도를 요구한다. JIT는 주로 수량이 많은 반복적인 제조 프로세스에 사용된다.

JIT의 역사

역사적으로 JIT 철학은 다음 2가지로부터 발생했다:

1. 생산품질을 개선하려는 일본의 바램. 당시 일본 기업들은 제조품질 특히 자동차 제조에 관련하여 나쁜 평판을 받고 있었다.
2. Kaizen[카이젠, 개선기법], 또한 지속적인 개선을 위한 일본식 방법.

JIT모델은 재고를 기획부실, 경직성(inflexibility), 잘못된 기계, 품질 문제 등에 대한 변명으로 보았다. JIT의 목표는 재고를 최소화하는 동시에 고객반응의 속도는 높이는 것이다. 재고는 변화하는 고객의 수용에 신속히 대응하는데 도움이 되지만, 어쩔 수 없이 원가가 증가하고 필요한 운전자본이 증가하게 한다.

1990년에 James Womack은 "The Machine That Changed The World"란 책에서 '린생산방식(Lean Manufacturing)'이라는 용어를 소개하였다. 또는 "린 생산 (Lean Production)"이라는 단어로도 불린다. 이러한 접근법의 배경에 있는 원칙은 Toyota의 Ohno가 개발한 기술과 내용이 많이 다르지 않다.

JIT의 관심영역

JIT 실행의 일반적인 관심영역은

• 재고 감소.
• 더 작은 생산 롯트(lot) 및 배치(batch) 크기.
• 품질 관리.
• 복잡성 감소와 투명성.
• 수평적 조직구조와 권한위임.
• 낭비 최소화.

외부 확장

인터넷 시대의 도래와 공급망계획(Supply Chain Planning) 소프트웨어를 통해 기업은 JIT 제조방법을 기업의 경계선 밖으로 확장하여 왔다. 공급자들이 조립공정에 필요할 때에만 공장으로 재고를 배달하도록 함으로써, 제조, 주문 배달 프로세스를 더욱 신속하고, 유연하며 효율적으로 하고 있다. 이러한 방식으로 통합된 공급네트워크(integrated supply network 또는 수요네트워크 demand network) 또는 전자공급망(Electronic Supply Chains)이 형성된다.
