Proactive maintenance is a preventive maintenance strategy for maintaining the reliability of machines or equipmentThe purpose of proactive maintenance is to view machine failure and similar problems as something that can be anticipated and dealt with before they occur.
Proactive maintenance consists of:
Because proactive maintenance methods are currently saving industries of all sizes thousands, even millions, of dollars on machine maintenance every year.
Reactive maintenance (also known as "breakdown maintenance") are repairs that are done when equipment has already broken down.
Reactive maintenance focuses on restoring the equipment to its normal operating condition. The broken-down equipment is returned to working within service specifications by replacing or repairing faulty parts and components. Emergency repairs cost3 to9 times more than planned repairs, so maintenance plans that rely on on reactive maintenance are generally the most expensive. Breakdown maintenance is so expensive because shutdowns happen during production runs (instead of pre-scheduled maintenance shutdowns during downtimes); because expedited shipping for spare parts costs much more than regular shipping; and because maintenance staff is often forced to work overtime to repair machinery.
Reactive maintenance is the response to work requests or identified need, usually identified by operations because a piece of equipment is broken or down. Response time to the calls and mean time to repair are the main objectives of this philosophy. The goal is to get it running as quick as you can to get the downtime down to an acceptable level. This is the approach of most organizations today. It may even incorporate what is termed as a preventive maintenance program and may use proactive technologies but only to identify and deal with symptoms of equipment failures.
The proactive approach responds primarily to equipment assessment, root cause analysis, and predictive procedures. The purpose of this philosophy is to predict and prevent failures before they occur. When the failure is initiated and found, the parts are order and the work is planned, scheduled, and executed during an outage instead of a downtime situation. The overwhelming majority of corrective, preventive, and modification work is generated internally in the maintenance function as a result of inspections and predictive procedures by both operations and maintenance departments. The goals of this method are zero breakdowns, continuous asset performance to established specifications, extended asset life and continuous improvement.

Reactive maintenance :
The oldest maintenance approach is reactive, or "run-to-failure." Equipment isn't repaired or replaced until it breaks.
Companies that rely solely on reactive maintenance find they have:
• Costly downtime. Equipment fails with little or no warning, so the process could be down until replacement parts arrive, resulting in lost revenue.
• Higher maintenance costs. Unexpected failures can increase overtime labor costs, as well as expedited delivery of replacement parts.
• Safety hazards. Failure with no warning could create a safety issue with the failing equipment or other units that might be affected.
Preventive maintenance :
The preventive maintenance philosophy is also known as time-based or planned maintenance.
The goal of this approach is to maintain equipment in a healthy condition. Selected service and part replacements are scheduled based on a time interval for each device — whether it needs it or not.
“You know you are in Reactive Maintenance When”:
solve the problems and the costs versus think ahead
Combination of the two options for the best results
Emergency maintenance times Haddou emergency problems
Regular maintenance ensures sustainability
Agree with Elke Woofter .
Proactive. Reactive maintenance can also mean cleaning up the mess.
