Reinventing Goal-Based Requirements Modeling

Understanding user needs, requirements, architecture specifications, and design specifications for a system holds up-most importance in a systems engineering project. The early phase requirements engineering deals with elicitation of goals, objectives and environment of the system under development and determine the needs and requirements of the various stakeholders. The needs, requirements should traced to the various rationales of stakeholder with their preferences. In this paper, we provide a goal-based requirements modeling methodology and language to understand the needs, requirements,... and represent them in a much clear manner to improve the quality of requirements written for the project and their early phase traceability. We also integrate the preference modeling of the various stakeholders for the various goals and hence provide a traceability for the requirements and their preferences in early phase of requirements engineering.
