Which technique is used for representing people and their roles in requirements modeling?

The correct answer is organizational modeling because this technique specifically focuses on identifying and defining the roles of individuals and groups within an organization in relation to their responsibilities and interactions in the requirements gathering and analysis process. Organizational modeling helps in visualizing the structure of the organization, including hierarchies, communication paths, and the various stakeholders involved in a project.

By using this technique, business analysts can better understand how different roles contribute to the project, ensuring that all relevant perspectives and needs are taken into account during requirements modeling. This understanding is crucial for effective collaboration and communication among stakeholders, ultimately leading to more accurate and complete requirements.

Other techniques mentioned, such as statistical analysis, market research, and resource allocation, serve different purposes. Statistical analysis involves interpreting quantitative data and trends, market research seeks to understand customer needs and market dynamics, and resource allocation focuses on the distribution of resources to meet project demands. While these techniques can support various aspects of projects, they do not specifically address the representation of people and their roles in the context of requirements modeling.
