This project focuses mainly on System Development Life Cycle Methodology on how to develop software that using the principles in the System Development Life Cycle. In stage of system analysis, we use the Unified Modelling Language (UML). This system provides additional functions like keeping a historical database for future and using GSM Modem as interface to the system for fast communication between the support and the help desk coordinator. Through implementing the system that records the usual problem and links to GSM Modem technologies for “SMS” that will improve the services, reduce cost and educate the users to solve their problem themselves. The support will be resolve as soon as possible since all the problems is been recorded and circulate to the support. The method of information gathering has been selected such as interview and research on the GSM Modem Product. We use the product GSM Module Siemens MC35 for the communication device for “SMS” Functions.
