TOWARDS A STRATEGIC REQUIREMENTS ELICITATION - A Proposal of the PRINCE Model

Requirements changes are sometimes pointed out as being one of the causes for project failure. Our solution to cope with this problem is to plan and manage requirements changes strategically. This paper introduces the PRINCE model that consists of 3+1 types of requirements elicitation processes based on the time of the maturation of the requirements elicitation activity. To explain the model, we show a real case with quantitative observations of a requirements elicitation process. When we are able to elaborate a strategy of requirements elicitation with the PRINCE model, we can elicit requirements by need of the physical development, rather than the theoretical development process model.
