Requirements are important in software development, product development, projects, processes, and systems. However, a review of the requirements literature indicates several problems. First, there is confusion between the terms 'requirements engineering' and 'requirements management.' Similarities and/or differences between the two terms are resolved through a literature review; resulting in comprehensive definitions of each term. Second, current literature recognizes the importance of requirements but offers few methodologies or solutions for defining and managing requirements. Hence, a flexible methodology or framework is provided for defining and managing requirements. Third, requirements methodologies are represented in various ways, each with their respective strengths and weaknesses. A tabular view and hybrid graphical view for representing the requirements process are provided.
