Software Reliability Software Reliability is the probability of failure-free software operation for a specified period of time in a specified environment. It differs from hardware reliability in that it reflects the design perfection, rather than manufacturing perfection. The high complexity of software is the major contributing factor of Software Reliability problems. Software reliability can be

The COCOMO Model The COCOMO model is an empirical model based on project experience. Well-documented, ‘independent’ model which is not tied to a specific software vendor. Long history from initial version published in 1981 (COCOMO-81) through various instantiations to COCOMO 2. COCOMO 2 takes into account different approaches to software development, reuse, etc. COCOMO 81

Estimation Techniques There is no simple way to make an accurate estimate of the effort required to develop a software system. Initial estimation techniques are based on inadequate information in a user requirement definition. People in the project may be unknown. Project cost estimates may be self-fulfilling. The estimate defines the budget and the product
