Information Required

You must provide the following data to perform maintainability prediction:

•	The Product Tree (Bill of materials)

•	The list of maintenance tasks or activities, including the number and description of all steps required to restore each replaceable item.

•	For each task, the list of skills, equipment and materials required to perform the task (optional, for maintenance planning only)

•	The failure rates associated with each replaceable item. These are taken automatically from the reliability prediction module.

•	The estimated or required fault isolation resolution, expressed as a percentage of faults isolated to each of the ambiguity groups.
