Every lesson so far taught one skill in isolation; these three case studies show them combined under schedule pressure. Each is generic and illustrative: no company, no product, no real report is quoted. Read them as worked examples of the method: hypotheses in writing, evidence before verdict, root cause to process change.
Lesson | After it you can... |
|---|---|
Trace an occasional boot hang to a torn configuration word. | |
Trace stream corruption to staggered reset release across FIFO pointers. | |
Explain how a late layout change reintroduced a signed-off reset bug. |
Read them in any order, but read each to the end: the process change at the close of each story is the lesson that outlives the bug.
Hypotheses written before evidence is gathered, each hypothesis killed by a named observation, and the fix paired with a process change so the class cannot recur.
