Design Decision

Runs judgment. Starts when a leadership team frames the question. It runs 5 times a week across 7 stations. One of those stations stops for a person and 6 are done by an agent, none 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 0

This service has at most one gate, so there is nothing to hand over without removing the last human decision.

People on the gates4 people

Each one is assumed to have 2,100 productive minutes a week, which is 35 hours.

Where an item spends its time

14% waiting on a person

86% in the agent lane

An item now takes 10,578 minutes of worked time end to end against 10,578 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 Design Decision

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

7 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.

Who runs it

Orchestration and accountability

Orchestrated by: Architecture Orchestrator
That orchestrator’s remit: Owns design decision work end to end inside Engineering. Runs 3 lines across 17 stations, drains the repeatable share into no shared tower, and holds 3 human gates.
Accountable person: Chief Architect
Sub-function: Architecture & Design
Shared spine tower: Not on the shared spine
Hand-over points: None — this service stays inside its function
