Ninety days of being asked nothing

The decision takes ninety days. It is the longest single wait in this record, half as long again as the next, and during all ninety of them nothing whatever is required of the person waiting.

What it is and is not

It waits on the receipt for the file, the doctor's check, the interview in person and the fingerprints. One step waits on it: the card in hand.

In a map of ninety-four dependencies, the slowest step has four predecessors and one successor. It is structurally almost trivial. Managers examining repeated handoffs may compare distributed team time records with the map, while keeping activity signals separate from judgements about quality.

A sixth of the waiting

Add up every wait in the map, done strictly one at a time, and the total is five hundred and fifty-three days. Ninety of those belong to this one step. Readers looking beyond this abstract map can compare it with material published by Harvard Business Review.

And yet the record's difficulty is almost entirely elsewhere. The decision is slow and not tangled; the account at a local bank is quick and stands in thirty-four rings. If somebody had to be given one figure about this map, the useful one is the second.

The slowest thing here is the easiest. That sentence is the whole argument against reading a dependency map as a schedule.

Why it does not expire

A decision, once made, stays made. It is one of the ten steps in the map with no clock on it, and it belongs to the category of things that record an event rather than a circumstance.

That matters because of what it sits between. Several of the things the decision waits on do expire — the doctor's check keeps for ninety days, and both the interview and the fingerprints are events that do not. So a person entering the decision has assembled a set of things of which at least one is on exactly the same clock as the wait itself.

A ninety-day check feeding a ninety-day wait is a coincidence of the map's round numbers, but the shape it produces is real: the thing most likely to have gone stale by the time a decision arrives is the thing the decision was waiting on.

The seven rings it stands in

All seven run through cover against illness and the card in hand. The decision is not the cause of any of them; it is carried into them by the card, which waits on the decision and on cover, and by cover, which waits on the card.

Three of those seven take more than two hundred days to walk, and all three are beaten by the clock on a place in the queue.

So the decision contributes ninety days to several laps that were already too long, without being the reason any of them is a lap.

What ninety days of nothing does to people

This record counts order and not experience, and it should not pretend otherwise. But the structural observation is available: the map's longest wait falls after everything has been submitted, when there is nothing left to arrange and no action that improves the outcome.

Every other wait in the record can be filled with some other errand. This one cannot, because by the time it starts, the only step that waits on it is the card, and the card waits on the decision.

The map's one period of enforced idleness arrives immediately after its hardest work and lasts a quarter of a year.

What it waits on, and why that is the risk

Four steps: the receipt for the file, a check by a doctor, an interview in person, and a sitting for fingerprints.

Three of the four are events and never expire. The fourth, the doctor's check, keeps for ninety days — exactly as long as the decision takes.

So the one perishable input to the map's longest wait has a life equal to the wait itself. If the check was done at the start of the ninety days and anything further is wanted at the end of them, it is on the exact margin.

That coincidence is a property of the map's round figures rather than a finding, and it is flagged here because a reader could reasonably build an argument on it. The robust version of the point is weaker and still worth having: the longest wait in this record has one input that can go stale while it is running.

A ninety-day wait with a ninety-day document inside it is the map's narrowest margin, and it exists by arithmetic rather than by design.

What this page is not

No country, office or kind of permission is named anywhere on this site, and ninety days is the map's own round figure, not a measurement of how long any decision takes anywhere.

What transfers is the relation: in systems of this shape the longest delay is usually the least entangled part, and effort spent on it returns nothing, while the entangled parts are quick and respond to being entered sideways.
