The Ask “Why” Fives Times problem solving technique

Ask “why” a problem is occurring and then ask “why” four more times…

For example…

  1. Why has the machine stopped?

A fuse blew because of an overload

  1. Why was there an overload

There wasn’t enough lubrication for the bearings 

  1. Why wasn’t there enough lubrication?

The pump wasn’t pumping enough

  1. Why wasn’t lubricant being pumped?

The pump shaft was vibrating as a result of abrasion

  1. Why was there abrasion?

There was no filter, allowing chips of material into the pump

Solution: Install a filter.

The inquiring mind solves problems.
