The Requirements Model and Behaviour in Specification of Requirements

The proper elicitation and specification of functional and non-functional requirements of an information system in a given environment is the first and the most critical task for the software developers today. The next critical activity is to properly understand these requirements so as to map them on to various design artifacts. In this paper, with the help of the requirements model, we present the behaviour part in the specification of requirements. We explain the behaviour in the specification with the help of dependencies using a mathematical model and a tree/graph so as to enhance the complete understanding of the requirements specification of the information system
