What is one challenge faced in the implementation of the 3-M System?

One significant challenge in the implementation of the 3-M System is the resistance to change from personnel who are accustomed to previous maintenance methods. This resistance can stem from several factors, including a comfort with established procedures, skepticism about new processes, or concerns regarding the effectiveness of the 3-M System compared to prior methods. When individuals or teams are faced with shifting how they conduct their work, it can create hurdles in fully adopting the new system. This challenge emphasizes the necessity for thorough training and clear communication about the benefits and efficiencies the 3-M System offers, thereby fostering a smoother transition and greater acceptance among personnel.

The other options, while they may also pose challenges in various instances, do not directly capture the inherent human factor involved in adopting a new maintenance management system like the 3-M System, making this the most pertinent challenge during implementation.
