Software Dependability Estimation Framework: AN OBJECT ORIENTED DESIGN PHASE PERSPECTIVE

Software systems are used in many areas,their failure can leads to loss of time and money. Developing systematic ways to relate the software dependability attributes provides a base for making objective decisions about design trade-offs. It enables engineers to make reasonably accurate predictions about dependability attributes that are free from biased and hidden assumptions. The ultimate objective is the ability to quantitatively evaluate multiple attributes of software dependability to arrive at a better overall system. Software Dependability is a useful measure in planning and controlling the resources during the development process so that high quality software can be developed. It is also a useful measure for giving user the confidence about software correctness. In this research work, the endeavor is to discover the attributes for dependability and to classify them as per their nature and type.Achieving dependability has always been a challenging task for the software developers. Ensuring the selection of suitable dependability attributes for the software development is crucial for the development of dependable software.
