Which type of analysis focuses on both the qualitative and quantitative aspects of system requirements?

Requirements analysis is the process that encompasses identifying, documenting, and managing the needs and requirements of system stakeholders. This analysis focuses on both qualitative aspects, such as user experiences and preferences, and quantitative aspects, including measurable requirements like performance metrics and system capabilities. By integrating both types of data, requirements analysis helps ensure that the final system aligns well with user needs and technical specifications, facilitating a comprehensive understanding of what the system must accomplish.

Functional analysis, by contrast, primarily deals with the functionalities required from the system rather than the broader qualitative and quantitative insights. Impact analysis assesses the consequences of changes within the system but does not focus on gathering detailed requirements. Cost-benefit analysis evaluates the financial implications of a project, focusing on economic viability rather than broad requirements. Thus, it is requirements analysis that effectively captures both the qualitative and quantitative dimensions essential for developing a successful system.
