Certified Maintenance & Reliability Professional (CMRP) Practice Exam

What is primary about the rework percentage benchmark in maintenance?

1. Should be less than 5%

2. Should be less than 2%

3. Should be implemented quarterly

4. Should be assessed monthly

The correct answer is: Should be less than 2%

The rework percentage benchmark in maintenance is based on the principle that excessive rework indicates inefficiencies in the maintenance process or the initial work quality. A benchmark of less than 2% is considered an ideal target because it suggests that maintenance tasks are being completed correctly the first time, minimizing the need for additional corrective actions. This low percentage reflects a well-maintained system and effective maintenance practices that contribute to operational reliability and efficiency. Setting the rework benchmark at such a low percentage encourages organizations to focus on quality assurance and continuous improvement in their maintenance activities. It promotes an environment where technicians are trained adequately, operational processes are refined, and equipment reliability is prioritized, ultimately leading to cost savings and enhanced productivity. Other options reference different thresholds or assessment frequencies, but maintaining a benchmark of less than 2% specifically underscores the importance of minimizing rework as part of a robust maintenance strategy.
