Textbook Problem

The four types of IT system maintenance also apply to other industries. Suppose you were in charge of aircraft maintenance for a small airline. What would be a specific example of each type of maintenance?

Program Plan Intro

Assuming you were in charge of aircraft maintenance for a small airline. Mention specific example for each type of maintenance among four types of maintenance that can apply to this industry.

Program Explanation

The four types of system maintenance are as follows:

Corrective Maintenance: Corrective maintenance is mainly performed in order to fix the error in the operational system. Corrective maintenance starts with identification of errors and ends with correction of errors in an operational system. Best approach to corrective maintenance is scaled-down version of the SDLC. In which investigation, analysis, design and testing is performed before system implementation. During corrective maintenance any new updates are first checked for in test environment and then updated in the operational system.

Example of corrective maintenance for an aircraft maintenance:

If any part of aircraft is damaged, then it has to repaired or replaced such as aircraft propeller is not working correctly then it will result in non-functioning of the system. Maintenance of such bugs will come under aircraft maintenance.

Adaptive maintenance: Adaptive maintenance is mainly performed to add new functions or features to the operational system which enhances its operability. Main scenario which leads to adaptive maintenance are changes in the procedure, goals and security needs of the organization.

Example of adaptive maintenance for an aircraft maintenance:

In case of aircraft maintenance if some new kind of missile module is being is added to the aircraft or any new type sensor that will come under the category of adaptive maintenance.

Perfective maintenance: Perfective maintenance is mainly performed to improve the efficiency, reliability and maintainability of the operational system...
