PROJECT PERFORMANCE ASSESSMENT SOFTWARE TESTING USING AGILE AND WATERFALL METHODOLOGIES

The relevance of the study is related to the need to choose design methodologies used in the software testing process, in the context of dynamically changing requirements and development deadlines. The article compares the effectiveness of Agile and Waterfall methodologies using the example of software implementation departments in IT companies. Metrics are proposed, with the help of which assessment of efficiency of design methodologies for software products of various purposes can be performed. The results of the study show that Agile methodology can increase the flexibility of the project process, speed up the identification of errors in software products and reduce the cost of fixing defects. At the same time, Waterfall’s approach provides greater control over development phases, but may be less effective in changing requirements.
