I've been skiing since I was a kid, and off-piste is where I learned the most about production software. The mountain punishes exactly the same mistake production systems do: trusting yesterday's conditions.
- The bulletin before the descent is the eval before the deploy. You skip neither because "yesterday everything was fine".
- The safety margin isn't pessimism. It's what lets you be aggressive where it counts.
- The most beautiful line and the right line sometimes coincide. When they don't, you pick the right one and you make it home.
- You descend as a group, one at a time, with clear regroup points. Incidents are handled the same way.
Once, on a night at altitude that had started as an easy hike, I saw up close how fast conditions flip a plan. It ended well, with a thinner margin than I like to tell. The long version another time.
Since then I design systems the way I prep an outing: bulletin, checks, margin. Then you drop in, and the fun is real.
// fresh powder doesn't forgive vibe-based risk assessment. Neither does production.
