Why Good Chassis Arrival Dates And VIN Numbers Are Critical

Managing a production schedule is difficult. To salesmen, customers, and individuals that are not involved in work order processing and production planning, it may seem like voodoo and witchcraft, seasoned with a little crazy. It is not. Production planning is based on 4 things:

    1.) Labor availability.
    2.) Raw material availability.
    3.) Long lead time component availability (critical path).
    4.) Chassis arrival date and VIN  (to identify chassis by J&J work order).

To describe something complex, simply, J&J’s production schedule is based on chassis arrival date and the first available production slot (labor) after the chassis arrival date. In certain cases, production may be scheduled based on a long lead time component delivery date (critical path), if that date occurs after the chassis arrival date and after first available production date. J&J has control of items 1 – 3 in the list above. J&J does not have control of number 4 – chassis arrival and VIN. You have control over accurate chassis arrival dates and accurate VIN. 

Bad chassis arrival dates cause major scheduling problems. The first time a chassis arrival date is missed, the corresponding work order rolls back in the schedule one week and a good order (chassis arrived) is pulled forward. If chassis arrival misses the second week, the work order is pulled from the production schedule and placed in “Unscheduled” purgatory until chassis arrival can be validated; then the work order is placed in the next available production slot. The next available slot may be significantly later than the original scheduled date. You may ask, “Why do you do that? It’s not fair.” J&J processes and produces hundreds of work orders a month. Bad chassis arrival dates wreak havoc on the production schedule. Our answer, “It is not fair to customers with work orders that have good chassis arrivals to allow schedule churn for poor communication.”

 What can I do to assure my work orders are produced when scheduled?
•  Provide the best possible chassis arrival date when you place your order with J&J.
• As chassis delivery dates from the OEM become firm, communicate those dates to your J&J sales representative or to the factory.
• Assure your body specifications, chassis arrival, and VINs are firm no later than 3 weeks before scheduled production at J&J.

Help us, help you satisfy your customers and meet their delivery expectations.
