Line-down risk
Line-down risk is the exposure to production stopping because a required material does not arrive in time. In lean or just-in-time operations there is little inventory buffer, so line-down risk is driven mainly by how early a delay is detected.
Also known as: line stoppage risk, production stoppage risk
Detection time is the variable that matters
Manufacturers cannot eliminate supplier delays. What they can change is how long a delay stays invisible.
A delay identified six weeks out is a procurement problem with several options: expedite, partial-ship, re-source, or resequence the build. The same delay identified three days out is a production problem with one option, which is usually expensive.
Line-down risk is therefore best understood as a function of detection latency rather than supplier reliability alone. Two organisations with identical supply bases can carry very different exposure purely because one hears about problems sooner.
Where detection latency comes from
The delay is usually knowable well before it is known. Suppliers commonly mention slippage in an email — as an aside, in a reply about something else, or in an attached revised confirmation.
The latency is the interval between the supplier saying it and the organisation registering it. That interval is where the recoverable options quietly expire.
How Evolinq handles it
Evolinq compresses detection latency by registering a date movement when the supplier communicates it, rather than when someone next reviews the order book.
Frequently asked questions
What is line-down risk?
Line-down risk is the exposure to production halting because required material does not arrive on time. It is highest in lean and just-in-time operations, where there is little inventory buffer to absorb a late delivery.
How do manufacturers reduce line-down risk?
Principally by shortening detection time. Since supplier delays cannot be eliminated, the practical lever is learning about a slipped commitment early enough that expediting, partial shipment, re-sourcing, or resequencing are still available.
