Aspects that are considered in the “before and after” comparison

1. Functionality: Before the repair, the machine may have been faulty or inefficient, whereas after the repair it regains its original functionality or even improved performance.
2. Condition: The condition of the machine may have been worn, damaged or obsolete before the repair, whereas after the repair it is in an improved condition with repaired or renewed parts.
3. Safety: There may have been safety problems before the repair that were rectified after the repair to ensure safe operation of the machine.
4. Efficiency: The overhaul may have helped to increase the efficiency of the machine by eliminating any problems or bottlenecks that may have affected its performance.
5. Cost-effectiveness: Maintenance can also help to extend the service life of the machine and avoid expensive downtimes, which can lead to cost savings in the long term.
