The company keeps the document, and the document keeps working

What is in the folder

• The register

  Every counted item on one line, in the five categories, each line carrying the day it was last verified against the room.

• The elevation

  The cabinet drawn unit by unit, labelled for function, with the spare units shown as outlines so the room left in the rack is legible at a glance.

• The conventions

  The short section that defines the numbering and naming used everywhere else, with examples taken from the building itself.

• The date page

  Licences, domains, certificates and line arrangements in date order on a single sheet.

• The gaps

  An entry for each thing that could not be established, and the reason: a cabinet that stayed shut, a run whose far end sits in someone else’s demise, an account nobody could place.

Formats a company can open on its own

The register travels as a plain spreadsheet and as a printed sheet. The elevation travels as an image and as the page it was drawn on. Nothing in the folder needs a licence to read, a login to reach, or a particular supplier to remain in business, because a record that can only be opened through somebody else is a record held on loan.

One printed copy goes into the cabinet itself. It is the least sophisticated part of the handover and reliably the most used, because the person standing at the rack with a cable in their hand is not the person at a desk with the spreadsheet open.

How it ages, and how that is measured

A folder starts going out of date the week it is written, and the honest response is to measure that rather than to pretend otherwise. Three figures do it: the items counted, the items with a written record, and the items that have changed since their record was made. From those comes the coverage — how much of the inventory is written up at all — and the stale count, which is how much of that writing no longer describes the room.

The coverage sheet on the standing index works it through step by step, including the question most worth asking before the next engagement is booked: how many records would have to be written to bring the document back to a stated level. Knowing that number turns maintenance from a feeling into a short list of work.
