  • 35. 어느날 T사의 공장 현장 책임자에게 들은 이야기원재료에서 완성까지 대략 4일 정도 걸립니다. 한 달에 20만대 정도를 이공장에서 출하하고 있습니다. 우리 그룹에서 두 번째로 큰 공장이지요.이곳에서는 크게 나누어 다섯 가지 공장을 거칩니다. 먼저 매입한 부품을확인하고, 그것을 조립할 수 있도록 준비합니다. 다음으로 조립을 하고,완성된 제품을 검품합니다. 아, 조립 라인에서 일하는 사람들 중에 지금은40%가 외국인입니다. 그건 그렇고, 검품에서 문제가 없으면 이곳에서 출하준비를 보냅니다. 사내에서는 부품의 확인과 매입을 사전 작업, 검품과 출하준비를 후반 작업이라고 부릅니다. 이 생산 라인도 여러 번 개선을거듭하면서 조업할 때는 생산성이 50% 가까이 올라갔습니다. 굉장하죠?다만 최근 갑자기 대형 오더가 들어와서 부품을 제때 조달하지 못하는문제도 갂갂히 발생하고 있습니다. 좀 더 빨리 수요를 알 수 있으면 좋을텐데요……… 조립 라인은 아무래도 인력이 많이 필요해서 외국인의 비율이높지만, 다른 공정은 그 정도는 아닙니다. 시스템이 잘 구축되어 있어서경력 사원 몇 명이 운영하고 있습니다. 부품은 가까운 곳에 있는 여섯 굮데협력 공장에서 저렴하게 들여옵니다. 출하는 지바에 있는 창고로 전량납입하여 그곳에서 각 영업소로 배송됩니다. 2-35
