Operational & Maintenance in the GSM telco industry or, more popular, called Managed Services has 2(two) main activities, i.e., Preventive Maintenance (PM) and Curative Maintenance (CM). The CM is recorded on the Trouble Ticket (TT) management system. The analyzing the TT and PM can optimize the performance availability (PA). When the PA is getting worse, we must review the most contributed TT and find out what the condition the sites are by reviewing the PM data. Perhaps we have got many problematic sites. The manager must plan some scenario: instantly by weekly action point, medium plan for monthly activities and annual projects. This paper describes how to prepare the quick solution as the 1st action. Installing 76 battery banks at 50 sites gives significant improvement of 0.12% performance availability. It is a low cost which can be covered by operational costs which are executed in a week. This result will be reported at the next weekly meeting.
