Criticality classification can be used for estimating the criticalities of the functions and the equipment in the system. Criticality classification produces important information to support the operations of maintenance, design and acquisition sections.
Typically criticality classification directs these sections with the following methods:
- Creating suitable maintenance and inspection programs primarily for the most critical functions and equipment
- Equipment spare part criticalities are derived straight from the equipment criticalities
- Recognizing critical functions and equipment already in the design phase to inform and support the development process
- Provides information for the acquisition section about the requirements of the critical equipment
The following PDF-document clarifies the criticality classification process for system equipment (unfortunately available only in Finnish):
