[Discussion] we are measuring reship at the wrong time and calling it noise
we are measuring reship at the wrong time and calling it noise. I have gone back and forth on this for months.
Why this board reports by lane and not by supplier.
Two members ordering from the same operation, in the same month, can see completely different transit times because they are on different routes with different carriers and different clearance points. Averaging them produces a supplier-level number that predicts nothing for either of them.
A lane — origin, destination, carrier, month — is the smallest thing that behaves consistently enough to be worth measuring. Once a route has a dozen reports behind it the median is genuinely useful, and that is what the tables on the source pages are built from.
The rigid outer with no rattle in it was the thing that told me most about that supplier, before I had tested anything.
Clearance took three days and the carrier took nine. I had been blaming the wrong half for two years.
If two or three other people have done the same thing we might actually learn something. Alone it is an anecdote.
best — the order this archive was captured in
Total transit decomposes into first mile, international leg, clearance and last mile. Only the first two are meaningfully under the shipper’s control and most reported variance sits in the last two.
A lane is an origin, a destination, a carrier and a season. Change any one and the distribution changes, which is why supplier-level shipping averages are close to meaningless.
Not convinced by four data points. That is not a lane yet, it is an anecdote with a route attached.
Median transit is the useful statistic. The minimum is a story about one shipment and the mean is dragged around by a single hold.
rigid outer packaging is the cheapest quality signal there is
That is the quoted lead time, not the observed transit. Both belong in the report and they are different columns.
no tracking numbers, ever
Origin, destination, carrier and month?
A quoted lead time is a commitment you can evaluate. Measuring quoted against actual across several orders tells you more about an operation than the raw speed does.
Careful — the supplier does not control the last mile and most of your variance is in it.
customs clearance time is not carrier time and they get conflated
Disagree. That is a customs hold, not a carrier delay, and lumping them together makes the lane table wrong.
Disagree.
This is why the lane table is organised the way it is. The supplier is not the unit.
How many shipments does your figure cover?
