Maintenance, Repair, and Operations

 Maintenance, repair, and operations involves fixing any sort of mechanical or electrical device should it become out of order or broken (known as repair, unscheduled or casualty maintenance). It also includes performing routine actions which keep the device in working order (known as scheduled maintenance) or prevent trouble from arising (preventive maintenance). MRO may be defined as, "All actions which have the objective of retaining or restoring an item in or to a state in which it can perform its required function. The actions include the combination of all technical and corresponding administrative, managerial, and supervision actions."




   Home repair involves the diagnosis and resolution of problems in a home, and is related to home maintenance to avoid such problems. Many types of repairs are "do it yourself" (DIY) projects, while others may be so complicated, time-consuming or risky as to suggest the assistance of a qualified handyman, property manager, contractor/builder, or other professionals. Repair is not necessarily the same as home improvement, although many improvements can result from repairs or maintenance.
A property manager or estate manager is a person or firm charged with operating a real estate property for a fee, when the owner is unable to personally attend to such details, or is not interested in doing so. The property may be individual title owned or it may be owned under sectional title, share block company owned and may be registered for residential, commercial office and retail or industrial use
 Often the costs of larger repairs will justify the alternative of investment in full-scale improvements. It may make just as much sense to upgrade a home system (with an improved one) as to repair it or incur ever-more-frequent and expensive maintenance for an inefficient, obsolete or dying system. For a DIY project, it is also useful to establish limits on how much time and money you're willing to invest before deciding a repair (or list of repairs) is overwhelming and discouraging, and less likely to ever be completed.
   A professional is a person who is paid to undertake a specialised set of tasks and to complete them for a fee. The traditional professions were doctors, lawyers, clergymen, and commissioned military officers. Today, the term is applied to estate agents, surveyors , environmental scientists, forensic scientists, educators, and many more. The term is also used in sports to differentiate amateur players from those who are paid — hence "professional footballer" and "professional golfer.
  
   Maintenance includes the installation or removal of a component from any Machine.


  Preventive maintenance (PM) has the following meanings:
The care and servicing by personnel for the purpose of maintaining equipment and facilities in satisfactory operating condition by providing for systematic inspection, detection, and correction of incipient failures either before they occur or before they develop into major defects.
Maintenance, including tests, measurements, adjustments, and parts replacement, performed specifically to prevent faults from occurring.


  Repairs and maintenance expense
The costs incurred to bring an asset back to an earlier condition or to keep the asset operating at its present condition (as opposed to improving the asset). For example, if a company truck is damaged, the cost to repair the damage is immediately debited to repairs and maintenance expense. Routine maintenance such as engine tune-ups, oil changes, radiator flushing, etc. is also debited to repairs and maintenance expense. (If an expenditure is made to improve the truck, such as adding a hydraulic lift to the truck or if an expenditure is a major repair that extends an asset's useful life, the amount is not expensed immediately; rather, the amount is recorded as an asset and is then depreciated over the truck's remaining useful life.)
