Lesson 01 · Change management
The Zoom Scheduler that taught me to plan twice, ship once.
I had just moved back to the Bay Area to join DoorDash after 13 years in LA, where I graduated from CSUN. One of my first projects was standing up a fleet of Zoom Scheduler rooms across offices using Apple Configurator and Jamf. I was heads down, confident in the playbook, and eager to ship. Midway through the rollout, a step I hadn't fully thought through unenrolled a batch of devices all at once. The next morning I was re-enrolling devices by hand and coordinating with folks across sites to get everyone back online.
What I took away from that week is a lesson I've carried into every IT program since. Careful planning and change management aren't bureaucracy, they're how you protect the people who depend on you. The unglamorous steps are the ones that turn a scary change into a boring one, and boring is what good IT should feel like.
A few habits I picked up from that rollout and have reached for ever since:
- Start with a pilot cohort of 5 to 10 devices. If something is going to go sideways, let it go sideways on machines where I can physically or remotely recover without touching anyone else's day.
- Know exactly what the rollback looks like before I ship the change. If I can't draw the undo in one diagram, the change isn't ready to leave my laptop.
- Name the blast radius out loud. Which sites, which devices, which humans, and what happens to them if I'm wrong. If the honest answer scares me, I slow down.
- Write the comms for the worst day, not the happy path. Tell the affected teams what's changing, when, what they'll feel, and how to reach me when they do. A heads-up before an outage is a very different experience than a surprise one.
- Put a real human on the other side of automation. For anything that touches an MDM, an identity provider, or an endpoint at fleet scale, I want a second pair of eyes on the plan before I hit run.
- Schedule the window with recovery time built in. I do the change when I still have the daylight to fix it, not right before I sign off.
