What did the collaboration on tasks look like — one analyst per task or jointly on larger ones?

A combined approach is usually used in systems analysis practice. For small and clearly defined tasks, one analyst is appointed, who is fully responsible for requirements gathering, analysis, and documentation. This helps increase accountability and depth of work.

For large, complex tasks or projects, a team of analysts is often formed, who work together on different aspects of the task — for example, one focuses on functional requirements, another on non-functional requirements, and a third on integrations. Collaborative work helps consider different perspectives, improve analysis quality, and reduce the risk of missing important details.

This approach is often accompanied by regular meetings, the use of common documentation tools (such as Confluence, Jira), and clear distribution of responsibilities.
