There is no document register behind this header. The version, the dates and the approver names are read off the governing rules this procedure runs inside, which is the closest thing the estate holds to a document control record. Nobody wrote these procedures. There is no document library behind this page and no Word file anywhere in the estate. Every procedure below is generated from rows this platform already holds: the line and its ordered stations, the owning team and the person accountable for it, the policy items bound to that team, and the governance gates seeded against the function. The steps, the owners, the gates, the approvers, the dwell times and the volumes are read straight off those rows. The sentences that join them together are generated. Read a procedure as the estate describing itself, not as a document somebody signed.

Purpose and scope

What this procedure is for and where it stops

To run dependency update to one repeatable standard inside Build, part of Engineering. more

Entry condition

Runs transactional. Starts when a request lands in the queue.

Exit condition

The unit clears escalate, released by Director, Platform Engineering. more

In scope

Every unit of dependency update raised inside Build, from the trigger below through to the final step.
5 of the 6 steps, which run without a person present.
1 decision that stops the line until a named person releases it.

Out of scope

Anything outside the envelope set by the owning team. It leaves the line at a gate and becomes the named approver's decision.
Work that belongs to another function. This line records no handoff, so nothing leaves it mid-flow.
The 5 steps carried on the shared AI GBS spine. They are done for this line but not by this function.

Who owns it

Runs the line

Build Orchestrator

Accountable person

Director, Platform Engineering

The end of the escalation path. Above them sits Engineering Chief of Staff for the function.

That team’s remit

Owns change work end to end inside Engineering. more

That remit describes the whole team, not this one procedure, so its counts are larger than the ones on this page.

Press run and a single unit enters at station 01. Each station takes exactly the dwell this platform records for it and is held by whoever the estate says holds it. more

what makes this path viable

The lanes are the recorded lanes. 1 of the 6 stations stop for a person and every one of them still does on this run.
Every one of the 1 decision is still taken by the person who holds it. The happy path is that each one is released first time, not that it is skipped.
The owning team is held to a 86% autonomy ceiling and this run sits at 61% unattended, inside it.
1 system is attributed across the stations, and 0 of them are connected. Nothing in this run has been watched executing against a real system of record.

what would have to change

One decision, held by Director, Platform Engineering. more

stays with a person

06 Escalate — The last decision on the line. Something on every procedure ends with a person, so this one is never offered.

what this run is, and what it is not

This is a run, not a forecast. more

Happy means nothing goes wrong: no station raises an exception, no gate sends the unit back, no rework loop fires and nothing sits in a queue between stations. more

The second clock is the allowance. more

A decision may be handed to the agent lane only if two things hold … more

The run reads the station rows only. more

What this run does not model: arrival patterns, contention between procedures for the same person, shift patterns, weekends, learning curves, and the cost of anything. more

Run it again, going wrong

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

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.
