Corrective maintenance:
The corrective maintenance measures that may be required for the CCPS are:
· Replace failed processes if any.
· Make a note of the processes in which the system is lagging and prepare corrective measures for the same.
· Update the processes and network with upcoming technology in services like speed of network, efficiency in operation etc.
· The e-mail received requesting for a booking may be required to be automatically updated at times.
· Data interpretation, which is considered as a major security concern at the time of building the system, may require some flexibility depending on various reasons.
Adaptive Maintenance:
· The online log system that is proposed may require additional options like extension of the car booking time, the data that is fixed for returning the car at the time of reservation may vary from that at delivery time, the model of the car at booking or reserving may differ from the car at pricking time.
· Creation of a new type of ports may be necessary based on the requirement. This might require additional software to be merged into the existing system.
· Add security patches to withstand the network threats that are increasing with technology.
· A new data field may be required in the new system, to place the name person and employee responsible for the order in the input screen.
Perfective maintenance:
The maintenance measures striving for the perfect working of the system can be referred as perfective maintenance measures.
· The network systems, which may be the best performing at the time of installation may not be the highest performing one, now. Thus, according to the new system, there may be a requirement to change the whole network to make the system highly efficient.
· If a particular operation like generating daily reports is made automatic, it would save the time of employee as well as the system.
· Compress the system files enabling the company to store large amounts of information.
· Enable end-user flexibility like customizing their own profile.
· Install more powerful network servers.
Preventive Maintenance:
· Preventive maintenance can only be done by proper observation and analysis of the system.
· Add the network security patches regularly to prevent virus and other data loss threats.
· Analyse every problem, solve it and check if it would produce any problems or errors in the future.
· Check the whole system regularly for consistency.
· Develop standard back-ups for all the important information files to prevent data loss caused by networks of the system.
