Development of a DSS module when preparing assessments for IT company clients

The article considers the relevance of the search for toolkit for objective software development complexity and timing assessment. The key purpose of this toolkit is to provide an IT company with the opportunity to objectively assess the labor intensity, the cost of a future software product at an early stage, on the one hand, and to ensure transparency in justifying an acceptable transaction price for the customer, on the other hand. A special feature of the IT industry is the intangible nature of the created product and, as a result, the challenge of choosing methods (metrics) for labor intensity assessment and predicting the timing of the software product implementation, which allows obtaining realistic data without serious time and financial costs, poses a certain difficulty. The results of the analysis and comparison of the most common methods of software development complexity assessment (in particular, IFPUG, UCP, COCOMOII, etc.), including identification of advantages and limitations, are presented. A generalized algorithm for the decision support system operation is proposed to reduce time and increase the validity of calculations when drawing up estimates by an IT company analyst as a part of the preparation of technical specifications. A description of individual screen forms of the decision support system designed module is provided.
