What are the two main types of maintenance strategies?

The two main types of maintenance strategies are indeed represented by the correct choice. Reactive maintenance refers to activities undertaken after a failure has occurred, addressing issues on an as-needed basis, which can lead to unplanned downtime and increased costs. In contrast, proactive maintenance emphasizes actions taken to prevent failures before they happen, including regular inspections and maintenance tasks that foresee potential issues, thereby enhancing overall equipment reliability.

This framework helps organizations optimize their asset management by balancing immediate responses with long-term planning. Understanding the distinction between these strategies allows maintenance teams to better allocate resources and schedule work effectively, ensuring higher operational efficiency and reducing the likelihood of costly breakdowns. Other options presented may encompass various approaches within the broader maintenance strategies but do not encapsulate the fundamental reactive versus proactive dichotomy that is critical for comprehensive maintenance planning.
