User oriented reliability is related to user profile and usage of the system. A system reliable for one user may not be reliable for other user. User oriented reliability can be represented as a function of the reliability of the components and frequency distribution of utilization of these components. In this work the Software Reliability of Library Management System module of SHARP software is calculated. For computation of software reliability, modular structure of chosen software was presented in form of Markov Chain Model. Reliabilities of sub modules are based on data received from end user survey of SHARP Software. Inter module transition probabilities are also based on this questionnaire. Effect of individual module over net system reliability is computed. Along with this criticality of each module is also estimated. Testing of these modules can be skipped and testing team might have more time to test more critical modules.
