Successful completion of IT-projects depends largely on the accuracy of the software requirements for the initial phase of project development. The main causes of difficulty in determining the requirements are the need to consider the wishes of a large number of potential stakeholders, a variety of types of requirements, a complex hierarchical structure of requirements, trace requirements. The use of prototypes, and especially the storyboard to determine the requirements for the implementation of large IT-projects in the initial phase of development will improve the accuracy of the claims, to minimize the need for changes in subsequent phases of project development. Reviewed and analyzed the main types of prototypes to determine the requirements for software, the most common tools storyboard requirements, methodological approaches to the implementation of storyboards.
