Everything Stops for Christmas. So What Is Still Going In?
By the middle of December most large organisations have stopped changing anything. It is a sensible precaution, and it is also the point in the year when the changes that do go through are the least well tested of any.
Somewhere in the middle of December, most large organisations stop changing things. Retail froze weeks ago. Payments, logistics and the utilities are not far behind.
It is a sensible precaution. It is also the point in the year when the changes that do go through are the least well tested of any.
1. A Freeze Is a Reasonable Precaution
The logic is sound and nobody should apologise for it. Consequences are highest when volumes peak, and cover is thinnest when people take leave.
For a retailer, a fortnight of trading decides the year. For a utility, winter is when the network is under most strain — and choosing to change less while the stakes are highest is not timidity.
Most organisations that freeze are doing something defensible, and doing it for the right reason.
2. Nothing Is Ever Fully Frozen
What actually happens is narrower than the announcement suggests. A freeze stops planned change. It does not stop all change, and it was never able to.
A security patch against a known exploit goes in. A safety-critical fix goes in. A defect preventing customers from being served goes in — whatever the notice circulated in November said about it.
So the channel stays open — narrower, busier, and used exclusively by the changes nobody has the option to defer.
3. The Exceptions Are the Least Tested Changes of the Year
Consider what that channel looks like in practice. The change is urgent by definition, because otherwise it would have waited until January.
It is written quickly, reviewed by whoever is not on leave, and released into an environment nobody has touched for several weeks — which is also an environment nobody has recently proved they can restore.
A freeze does not remove risk from the period. It concentrates it into the handful of changes with the least time, the fewest reviewers and the most pressure behind them.
4. The Backlog Has to Land Somewhere
Everything deferred does not disappear. It queues — and unlike most queues, this one has a date on which it is all released at once.
In January it arrives together — a large batch, released after a long gap, by people who have had three weeks away from what they wrote.
Which is close to the least safe shape a release can take. The freeze bought a quiet December and paid for it with a difficult February.
5. The Length of It Is an Admission
The duration is worth reading carefully. An organisation needing ten weeks of stillness to feel safe has said something quite specific about its own release process.
It has said that change is not trusted to be reversible. Once something is in, getting it back out again is neither quick nor certain, and everybody involved knows it.
That is a better diagnostic than most assurance reports and it costs nothing to obtain — but it goes unread, because a freeze is treated as prudence rather than as a symptom of anything.
6. Some Organisations Cannot Have One
In parts of the economy the option barely exists. An ambulance service, an acute trust, a railway — winter is simultaneously the period of heaviest demand and the period when the most needs fixing.
Freezing through it would mean declining to correct problems during the very season in which they are being found. That is not a position anybody can hold for long, and nobody seriously tries.
So these organisations run something more honest than a freeze: a raised threshold, with a named person deciding case by case what clears it and what waits.
7. What Is Worth Doing Instead
The useful version is narrower and better governed than a blanket stop. Four things make most of the difference:
- which systems are genuinely frozen, and which were quietly never included
- who decides an exception, and whether that person is reachable on the 27th
- how each change is reversed, established before the freeze rather than during it
- what is queued for January, and in what order it will be let out
The third decides how a difficult night goes, and it is almost always assumed rather than checked.
8. Read the Freeze as a Measurement
A freeze is a control. It is also a reading — and unlike most readings, this one is free and already taken.
An organisation confident it can release small changes and reverse them quickly needs only a short one, covering the busiest days. An organisation needing two months has located its own problem without meaning to.
Neither is a failure. The difference is whether anybody has noticed what the freeze is saying about the other eleven months.
Final Thought
December is described as the month when nothing happens. In most large organisations it is the month when change is at its most concentrated, its most urgent and its least examined.
The freeze itself is not the problem. Treating it as an answer, rather than as evidence about how the rest of the year is run, is.
