Runs transactional. Starts when a threshold is crossed. It runs 6,838 times a week across 6 stations. 2 of those stations stop for a person and 4 are done by an agent, 3 of them on the shared spine.

Run it

Change the volume, move the autonomy line, release a gate, and watch what happens to the hours in each lane and to the time it takes one run to get through. more

Decisions handed to agents0 of 2

Cheapest decision first. The last gate never moves: something on this service always ends with a person.

Where an item spends its time

44% waiting on a person

56% in the agent lane

An item now takes 578 minutes of worked time end to end against 578 in the recorded estate, a change of +0%. This is worked time, not calendar time: nothing here models a queue or a weekend.

What this model is, on Pull Request Review

The simulation is arithmetic on the estate, not a queueing model. more

How it runs

Run it again, going wrong

The same unit and the same stations, broken the way the estate already records breaking. more

6 stations, walked twice

Once clean, once with the categories the estate counts

This is the same unit on the same stations, breaking. more

No break below was chosen. more

One play head, two tracks, the same scale. The clean run stops when it runs out of stations; the other one keeps going.

What this run cannot claim

These breaks are shown together on one unit so the shape of a bad day fits on one screen. more

The separation register records a duty conflict against a sub-function and a named post, not against one procedure. more

Two clocks run. Worked time is the sum of the time the work is actually being done … more

Who runs it

Orchestration and accountability

Orchestrated by: Code Quality Orchestrator
That orchestrator’s remit: Owns pull request work end to end inside Engineering. Runs 3 lines across 14 stations, drains the repeatable share into no shared tower, and holds 5 human gates.
Accountable person: Director, Engineering Quality
Sub-function: Code Review & Quality
Shared spine tower: Not on the shared spine
Hand-over points: None — this service stays inside its function
