Maintenance evaluation is an assessment of an organization's current maintenance arrangements to identify areas for improvement. It involves interviews, observations, and expert opinion to reveal strengths and weaknesses compared to best practices. The goals of evaluation are to set job standards, avoid overstaffing/understaffing, and evaluate maintenance functions using objective indices from reports, work audits, and subjective estimates. Evaluation methods include reports on work completed, analyzing downtime and repair times, and using ratios to assess maintenance costs and personnel performance.

6. Evaluation through reports

• The evaluation is done on the basis of reports which are prepared at fixed
time intervals (monthly or yearly) giving details of the equipment
serviced/maintained during period.
• The real evaluation of the process depends upon the accuracy of the
reports.
• The reports should give the complete picture of the maintenance function
so that the corrective measures can be taken.

7. Work Auditing
• In this method total time for which the equipment is not available for
production work and total time taken by maintenance staff to attend the fault
is analyzed .
• The step by step progress of randomly selected job is recorded to highlight the
delays caused.
• The delay may be because of poor planning of repair work or non availability
of spare parts .
• It enable the maintenance foreman to understand the weak points . The areas
where improvements are possible can be identified and corrective actions
initiated accordingly.

9. Objective Evaluation
•The ratios given above helps helpful in assessing the maintenance costs.
•The ratios defined above can be computed on monthly or yearly basis.
•These ratios are indicative of the performance of maintenance
personnel.

10. Subjective Evaluation
