Paradigm is defined as a body of knowledge that selects and highlights certain issues for study. It includes assumptions about how a particular phenomenon ought to be studied and the kinds of experimental methods and measures that are appropriate to use.
It is a model or framework for observation and understanding, which shapes both what people see and how they understand it. Paradigm, moreover, is a term which is used to describe a set of rules and regulations that establish boundaries and explain how to be successful solving problems within the given boundaries.
