Defining goals up front with your contract manufacturer can help you properly establish your terms and conditions to establish a win-win partnership between the two parties. In general, this is what you are looking for:
- Lowest total cost
- Reduced Inventory
- Minimized risk of obsolete inventory
- Limited purchase order commitments
- No overproduction
- Reduced wait times and logistics costs
- Streamlined work flow
- Improved responsiveness to changes in demand
- Minimized impact of engineering design changes to manufacturing costs
In addition, the contract manufacturer finds it beneficial to have an annual contract with the customer to allow for better control of the manufacturing process, shipments and the production range. It also provides contract manufacturers the ability to negotiate with their vendors, taking advantage of economical order quantity. The annual contract doesn’t necessarily mean the customer takes on more liability but it provides the contract manufacturer with a better planning window. The customer can control his liability by doing the following:
Shipments based on Customer release
- No reschedules required
- Line resizing when appropriate / based on forecast
- Cancellation based on 30,60,& 90 day windows
Customer determines production range
- For example; 100 to 150 per month
- Additional provisions for Ramp Planning
- Provides rolling six month forecast
We recommend the following guidelines for defining fixed windows for reschedules and cancellations:
First 30 day window: All material and labor applied up to the stop date is 100% the responsibility of the customer.
Second 30 day window: No labor, and only material on hand with lead times greater than 4 weeks.
Third 30 day window: No labor and only material with lead times greater than 8 weeks. Plus material that is in place due to mutual agreement for the purpose of meeting release ranges and ramp readiness plan.
Engineering Change Orders: Customer is responsible for excess and obsolete material due to ECO’s inside negotiated windows for reschedules and cancellations.
To summarize, the benefits to established terms and conditions could help a relationship by providing:
- forecast visibility to help lower liability, negotiate best pricing and enter into Kanban agreements,
- consumption of material based on customer demand to simplify production planning and support and eliminate interruptions in material flow,
- the most efficient utilization of space.
