In this paper, we are examining the implementation of Just-In-Time methodology in Ford for its latest small car KA; possibly one of the most interesting manufacturing revolution where companies involved in the production are integrated not only in their business processes moreover in their physical plants. The concept has been successfully developed and implemented in Valencia, Spain and is due to be adopted in other Ford production plants. The case study clearly shows how companies can work together in a harmonic and synchronised system meeting probably the most idealistic manufacturing principles (JIT) to produce the best quality product within the shortest time frame with minimum/no wastage and cost-effective to all parties. Careful production planning, cost-benefit analysis, adequate outsourcing plans and customer orientation are being praises as the key success factors of this amazing Just-In-Time concept.
