APPROACH FOR ENHANCING THE RELIABILITY OF SOFTWARE

Reliability is always important in all systems but sometimes it is more important than other quality attributes, especially inmission critical systems where the severity of consequence resulting from failure is very high. Software reliabilityengineering is focused on comprehensive techniques for developing reliable software and for proper assessment andimprovement of reliability. Reliability metrics, models and measurements form an essential part of software reliabilityengineering process. Appropriate metrics, models and measurement techniques should be applied to produce reliablesoftware. Hence, it is the intention to develop some approaches to enhance the reliability of software by the analysis of thestructure of the software, execution scenario for various inputs and operational profile.Keywords: Software Reliability, Rate of occurrence of failure (ROCOF), Mean Time to Failure (MTTF),Hardware Reliability, Mean Time between Failure (MTBR)
