The IT Subject Matter Expert Logbook
The decision was right. Six months later, nobody can say why.
The meeting notes are gone and the people who were in the room have moved teams. Enterprise work outlives the meeting it was decided in — and most of it is never written down anywhere a successor can find.
- Architecture decision records, with the decision written in full sentences and sign-off lines
- A fleet deployment tracker: pilot plus five waves, and the rollback trigger set before the pilot
- Incident reviews on a two-page spread — timeline and impact left, root cause and actions right
- Knowledge transfer and SOPs, from trigger and prerequisites to how you know it worked

Decisions that survive handover
Current state against desired state, security and compliance checks, and the decision in full sentences, with sign-off lines for each zone.
Changes, expiries and vendors
One line per change that touched production, a tracker for every certificate and licence with an end date, and a log of what the vendor actually promised.
When it goes wrong
Incident reviews as a full spread, so the timeline and the root cause sit side by side — and SOPs that include when a procedure fails and the hard stops.
Filled in once, inherited by the next person
- Naming conventions — pattern and worked example for twelve object types
- Environment reference — directory, site servers, tenant, certificate authority
- Maintenance windows — and key contacts
- Escalation ladder — so a new team member inherits it instead of asking
- Automation canvas — a 5 mm dot grid with execution-safety prompts
For the person who is accountable
Architects, systems and infrastructure engineers, endpoint and fleet leads, and platform and automation specialists — anyone whose decisions have to survive their own handover.
Undated, black ink on white paper with a matte cover. Large enough to sketch a topology on, and sturdy enough to live on a desk for a year.
