Risk Assessment of Mobile Phones Using Failure Mode and Effect Analysis

Seen from many aspects the use of mobile phones implies the existence of a risk to users of this kind of equipment. An additional problem is that for the radio equipment there is still no general standard which defines principles for the design of this type of equipment with the emphasis on assessment and risk reduction. Failure in hardware and software in mobile phones is one of possible risks. The effects of failure cause problems in mobile phones, customer dissatisfaction, cost ineffectiveness, poor marketing for manufacturers, etc. The causes and effects of failure analysis will help the user and manufacturer to understand the system more effectively and also to avoid the failures as much as possible. This paper presents the failure mode and effect analysis of the mobile phone. The aim of the research is to analyze the whole mobile phone system with its components and their potential failure modes. Based on the proposed analysis, the paper shows calculation of Risk Priority Numbers for various mobile phone components. The results of this research represent attachment to the general methodology of assessment and risk reduction of mobile phones.
