How do you get partner status into the schedule?

Via partner portals (API or scheduled check-in), shipment confirmations, or an explicit phone/email cadence. Static lead-time offsets are not status.

Should you keep alternate outside processors?

For critical operations, yes. The scheduler should route to the partner with the lowest realistic turnaround, not the cheapest quote.

How does outside processing interact with finite capacity?

It is one more constrained resource. A finite-capacity scheduler that does not model partner queues is treating their capacity as infinite, with the same failure modes as treating in-house machines as infinite.

Outside Processing — Manufacturing Scheduling Glossary

Definition

Outside processing is any operation in a part's routing that is performed by an external partner rather than in-house — typically heat treatment, plating, anodize, painting, NDT, or specialty machining. Each partner has its own queue, capacity, calendar, and slip pattern, none of which are visible to an ERP that treats outside processing as a fixed lead-time offset.

Why it matters

In shops with heavy outside processing, partner delays are one of the top three causes of OTD miss. The official schedule assumes a 5-day plating turnaround; the partner is at 9 days this week and the shop does not know until the parts fail to ship back. The receiving operation cannot start, downstream queues empty, and the rest of the week rearranges itself.

Common failure mode

The ERP schedule treats heat treat as a 5-day fixed offset. The partner is overloaded. Parts return after 11 days. Three downstream operations are starved. Two customer commitments slip. The shop only learns the partner is slow when the parts do not arrive.

How Skody approaches it

Skody models each outside-processing partner with its own calendar, current queue, and recent turnaround actuals. When partner status changes, downstream operations are replanned and at-risk orders surface with the named partner constraint.

Production Rerouting

Moving a job from its planned machine or partner to an alternate when conditions change.

Schedule Instability

When the schedule changes so often that the floor cannot rely on it.

Queue Buildup

The growth of work waiting in front of a resource when arrival rate exceeds processing rate.

Manufacturing Variability

The unpredictable variation in setup, run, and queue times that makes plans drift from reality.
