This document outlines the PAID problem solving process, which consists of 5 steps: (1) Problem Statement - defining the problem in a single sentence, (2) Analyze the Problem - examining what is wrong and right, (3) Identify Likely Causes - considering what has changed and potential causes, (4) Define Actual Causes - determining the most likely explanation, and (5) proving the identified cause. The document provides guidance on techniques for each step such as brainstorming, questioning, and herringbones to thoroughly analyze problems and identify root causes.
