Combined approach technique in payment system development projects

Thanks to Scrum, a high maintenance of the code (the ability to make changes with minimal effort) was achieved - the cost of changes to the product is almost equivalent to the cost of developing similar product functions at the beginning of the project, which is rarely achieved in the so-called “waterfall” production model, which is characterized by exponential increase in the cost of change as the project progresses. Scrum - project management method. Agile - a set of concepts, principles and techniques (practices) that allow you to quickly and easily perform modeling and documentation in software development projects. A payment system is a set of rules, procedures, and technical infrastructure that ensure the transfer of value from one economic subject to another. Flexible methodology - a series of software development approaches focused on the use of iterative development.
