Factors Affecting Maintainability

• Training of maintenance crew (poorly trained crew will take unduly more time).
• Maintenance procedure (complicated procedure delay maintenance period).
• Maintenance guidance and monitoring (Lack of proper guidance and monitoring will increase the maintainability).
• Availability of maintenance manual (unavailability proper maintenance manual delay the time).
• Safety requirements (higher safety requirements delay the process.
• Standardisation prescribed and to be achieved (standardisation needs of high degree will take more time to achieve).
• Accessibility (of equipment, tolls, gadgets necessary to carry out maintenance).
• Expertise required.
• Special items (of extra-ordinary quality and specifications) essential for replacements.
