A Framework for Requirement Elicitation, Analysis, Documentation and Prioritisation under Uncertainty

This paper offers a pluralistic framework for coping with requirements in the early phases of design where there is lack of knowledge about a system, its architect and functions. The framework is used to elicit, analyze, document and prioritize the requirements. It embeds probabilistic approach and offers the knowledge based selection of requirements. The inherited probabilistic approach facilitates communication and accommodates tolerance and flexibility in sharing opinions and embraces uncertain information. This framework uses a graphical tool to intuitively collect uncertain information. It uses the probability theory to process that. It also facilitates storage and reuse of the collected information. An example shows the application of this method through the ColdFacts project
