Root Cause Analysis & Problem Solving

Yogendra Sagar Mishra

Labs assume you’ve already got a note-taking setup; lost a few minutes wrangling that. After that, the exercises forced me to face some sloppy habits, especially jumping to solutions before framing the problem. The Constraint Ladder in Week 3 stuck with me; writing the first arch sketch, then deleting half of it, felt like a PR review in slow motion. Useful tie-ins to day job stuff—how this shows up in prod incidents, or when a CI failure sends you chasing noise. It’s beginner-level, but not fluffy. Short videos, lots of doing. I’ve already changed how I size tasks and decide what actually needs attention vs. what can wait.

FFT basics section using the imbalance vs misalignment spectrum example stuck; it's good, but wished there was more on bearing fault frequencies.

Sat through plenty of intro courses; this one actually has teeth. The Module 2 walkthrough on cold vs hot commissioning—especially the FAT/SAT handoff and interlock verification before first power-on—stuck, because it mapped cleanly to prod cutover with obs checks tied back to the infra arch. Some pacing felt rushed, and I wasn't sold on the quiz gating, but the checklists translate straight to a repo PR or runbook. Walking away with fewer open questions and answers I'm more confident shipping.

Short, practical reps—like the Chapter 2 'Status Update Rewrite' where you cut a rambling Slack into a 5-bullet PR summary, kept it useful between meetings. It's beginner-level, mostly, but I've already used the 'ask-back' checklist in a prod incident review; wished there was more on async comms across infra/k8s teams.
