I have recently completed FMEA assessments for our critical equipment and now need to categorize them as Class A - essential machines, Class B - less crucial machines, and Class C - run-to-failure (following the McKinsey roadmap for equipment classification). Considering both the likelihood and impact of failure, can you advise me on how to proceed with this classification? Please refer to the attached file ARO_Manual_Guns.xls for more details.
The importance of effective maintenance strategies cannot be overstated, especially in light of the Enron scandal. While some assets may not necessarily need predictive maintenance (PdM) technologies, utilizing root cause analysis (RCA) to extend their lifespan to the fullest extent possible is crucial. Cutting corners and allowing assets to deteriorate should never be an option. Remember, those who neglect the small details should not be trusted with larger responsibilities.
Sometimes, it can be more cost-effective to replace and install a new unit than to spend time and money on maintenance. Going with a "run to fail" approach may ultimately prove to be a more economical solution.
Hello Giga, I trust this information will be beneficial for your equipment ranking system. The goal is to categorize machines into Rank A, Rank B, and Rank C to prioritize maintenance tasks effectively. It is crucial to give priority to Rank A machines as they are critical equipment. However, it is also important to consider if it is more cost-effective to restore or retire equipment in Rank A if it frequently fails due to aging. Please find the attachment for the Machine Ranking Matrix for further reference. Thank you.
After a quick look at your attached file, I would suggest starting your classification by considering the criticality of each machine's function within your operations. Class A machines, being essential, should include machinery whose failure would significantly impact production or operational safety. These are the machines identified in your FMEA assessment as having both high likelihood and high impact. Class B are less crucial and their failure, while inconvenient, won't halt production entirely. Lastly, Class C machines can afford to run-to-failure; these are machines that can be easily replaced or repaired and whose failure does not significantly impact operations. This categorization should facilitate prioritization in maintenance scheduling, optimizing your resource allocation.

Answer: Answer: The classification of equipment into Class A, B, or C is typically based on the criticality of the equipment in relation to the likelihood and impact of failure. Essential machines (Class A) are those that have high likelihood and high impact of failure, less crucial machines (Class B) have moderate likelihood and impact, and run-to-failure machines (Class C) have low likelihood and impact. Refer to the McKinsey roadmap for equipment classification for detailed guidance.
Answer: Answer: Examples of equipment under Class A (essential machines) could include critical production equipment, safety systems, or key infrastructure components. Less crucial machines (Class B) may include auxiliary equipment or backup systems, while run-to-failure machines (Class C) could be non-critical assets where failure consequences are minimal.
Answer: Answer: Failure Mode and Effects Analysis (FMEA) assessments provide valuable insights into the potential failure modes, their causes, and consequences. By considering the results of FMEA, such as the severity of failure effects, occurrence likelihood, and detection ability, you can make informed decisions on categorizing equipment based
