The aim of this project is to develop a web-based system that implement the rule-based technique to assist technician to diagnose mobile phone failure. The rule-based technique is used due to the suitability of the technique for specific problems or situations. The objectives of this project are to gather and analyze data from Nullfix Mobile Seri Kembangan, to identify the rules for this system, to design the system by using rule-based technique and to develop the system to diagnose mobile phone failure. This project is successfully developed by performing rule-based technique. The system works by the technician selecting conditions that are related to the phone problem to know the solutions. The result of this system is that it displays the type of failure with the associated solution and the reasoning for why the solution is selected.
