Therefore, most people do not intentionally make bad decisions that lead to failure. In most cases, the decisions were made with good intentions but with bad information.

These are the rules and regulations in a plant the policies, procedures and specifications that apply to training systems, stores systems and other aspects of daily operation. They are the sources of information on which people base their decisions.
