Ops Knowledge Garden
You got promoted because you were good in the field. Nobody told you the job was about to change completely.
That was the original reason I built this site: the playbook I wish somebody had given me.
It has become something larger.
I spent about ten years in EMS as an EMT, field training officer, and operations supervisor. I kept writing after I left the field. About leadership, incident investigation, operational systems, safety, the limits of formal records, and eventually the company I started building from those ideas.
This Garden is the public part of that record: selected from my private notes, cleaned up enough to be useful, but not cleaned until the uncertainty and history disappear.
It is not a raw export. I decide what belongs here. About These Notes explains the boundary and the slightly strange reason I want to preserve the thinking while I am still inside it.
Find your way in
If you just got promoted into a supervisory role and need something useful now, start with First 90 Days.
If you are developing other people, follow Training FTOs, The Debrief, and Stop Being the Answer.
If you are trying to understand the systems thinking underneath my work, start with Build the Sprinkler System, The Report Was Accurate. It Was Still Incomplete., and What the Form Can’t See.
The Garden Map shows the current structure. Open Questions collects the parts I have not resolved.
Notes currently at the center
- What the Form Can’t See — the instrument gap, why one-at-a-time review cannot close it, and the honest limits of reading a record of losses
- Build the Sprinkler System — why competent recovery can conceal the need for prevention
- The Report Was Accurate. It Was Still Incomplete. — the record problem underneath chatIR
- Stop Being the Answer — how a supervisor’s expertise can create dependence
- Recognition Is Evidence of Attention — making otherwise invisible work legible
- A Problem Passed Around Is a Problem Owned by Nobody — why handoffs create motion without resolution
- Fleet Safety — the measured accident-reduction project where several of these ideas became real
Field Tools
The practical EMS-supervision material is still here. Seven printable tools grew from the methods in these notes: investigation forms, coaching scorecards, interview guides, and a supervisor self-evaluation. Browse Field Tools, or keep the EMS Supervisor Field Guide as a PDF. It is free with your email.
About
I’m Christopher Harper, founder of chatIR. I am trying to build software that helps operational and safety teams recover context, see recurring conditions, and make better-informed decisions without pretending the software should replace their judgment.
This site is the thinking. chatIR is one tool growing from it. If something here is useful, or if you think I have it wrong, I would like to hear about it.
