IT:AD:5 Whys

* (UP)


5 Whys is a process to delve further and find the route cause of errors.

The key is to encourage the trouble-shooter to avoid assumptions and logic traps and instead trace the chain of causality in direct increments from the effect through any layers of abstraction to a root cause that still has some connection to the original problem.

  • Note that the number of iterations is not fixed at 5. Just anecdotally is the most common number of iterations before the root cause is found.
