Reactive Maintenance in Software Engineering
Reactive Maintenance, as name suggests, is a maintenance strategy that is applied when failure has already occurred. In this, assets such as equipment, component, etc. are repaired and restored to their normal operating functions only after their failure or are broken down or their poor performance. It simply follows Newton’s third law of motion that states that “for every action, there is an equal and opposite reaction”. It simply describes nature of force and human nature to react to any action as per requirement.
Similarly, reactive maintenance is also performed to fix asset after it’s broken or is failed. Reactive maintenance is started and initiated in some cases are equipment failure, requiring repair, or restoring equipment to its normal condition. But one should look for other maintenance strategies as someone has said that “prevention is better than cure”. It’s better to prevent equipment from failure than to repair it after failure.
There are several advantages of reactive maintenance as given below :
- Requires less time and money :
Obviously, if someone does not maintain unbroken equipment, that simply means there is no cost required for maintaining equipment. Money is saved rather than spending it on maintenance of equipment. In simple words, we can say one can save money and time by doing nothing rather than spending time and money by doing something. In reactive maintenance, it is similar to one save money and time both by not maintaining equipment.
- Requires fewer members :
In preventive maintenance, additional members are required to maintain equipment who has to regularly check condition of equipment. In this type of maintenance strategy, no maintenance of equipment is required so it requires fewer members to perform repair after equipment breakdown. Small group of members is required to perform repair after failure.
- No planning needed :
In preventive maintenance, it requires a lot of planning to maintain equipment and prevent them from failure. But, in reactive maintenance, less planning is required as one does not need to plan for preventing equipment from failure.
Other than advantages, there are several disadvantages of reactive maintenance as given below :
- Safety issues :
When proper planning is done to perform each task in scheduled and appropriate manner, then one can maintain and perform tasks with complete safety. But in reactive maintenance, working team is under pressure as planning is not done in such type of maintenance strategy. Same issue can reoccur after repairment also if proper maintenance strategy is not applied.
- More expensive :
If proper maintenance strategy is not applied, then system can fail at any time during working hours or during production. It can cause greater damage to overall system and can lead to decrease in production and increase in repair cost.
- Time-consuming :
Reactive maintenance is more time-consuming as, after failure, team members take much more time to take corrective actions to repair equipment. This also leads to delay in production.
- Inefficient use of resources :
Repairment of equipment requires greater use of resources and time consuming also. One needs to order corrective parts and also wait to be issued.
