VI. Maintainability and Availability
B. Maintenance and testing analysis
2. Corrective maintenance analysis (Apply)
Describe the elements of corrective maintenance analysis (e.g., fault-isolation time, repair/replace time, skill level, crew hours) and apply them in specific situations.
Dealing efficiently with downtime or system failures saves time and money and done well may even improve your operation.

An initial step in any problem solving tasks is to understand the available information and define the boundaries of the study. Starting with a Pareto of the problems may provide a starting point to narrow the focus on the study to the most common or serious problems. Then move to the step of understanding the causes of the problems.
