Why launches fail
On This Lesson 4 topics
This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.
In this lesson
name the recurring causes of failed launches so a review can target them.
Planned topics
- Most launch failures are not bugs in the happy path: they are missing alerts, untested capacity, unrehearsed rollback, and unclear ownership.
- Big-bang cutovers hide the cause: too many changes land at once to tell which one broke things.
- "Done" meant "merged", not "operable": nobody asked who is paged and what they do.
- Launch pressure turns checklists into paperwork when the decision is already made.
Draft outline details
Demonstration
A table of three past launches (yours or public postmortems): trigger, what was missing (alert, capacity, rollback, owner), and which readiness question would have caught it.
Check your understanding
Why is a big-bang launch harder to debug than a staged one?
Show answer
Many changes land together, so a failure cannot be attributed to one of them.
