The document provides guidance on problem solving techniques, with an emphasis on identifying the root cause rather than just fixing the problem. It outlines 8 keys to better problem solving, including keeping analyses simple, focusing on performance differences rather than possible causes, thoroughly documenting all steps, and maintaining discipline. The document then provides a specific methodology for problem solving, beginning with defining whether the problem is new or long-standing, writing a general and defined problem statement, considering any recent changes, establishing performance metrics for evaluation, and writing a final problem statement incorporating the metrics and comparison strategy.
