The Relation between Software Development Methodologies and Factors Affecting Software Reliability

Methodology of software development is a system of principles, as well as a set of ideas, concepts, approaches, methods and tools that determine the style of software development. The choice and use of a particular methodology of software development ultimately affects the reliability indices of the software product. This paper has analyzed the current approaches to the use of the most common methodologies of software development and identified 15 major factors that affect the quality and reliability of software. Structuring of certain factors in relation to the stages of development of the software lifecycle has been carried out and the factors of the initial stage of the life cycle have been highlighted that most influence the quality and reliability of the final product.
