What was the team composition? Was it mono-functional or cross-functional?

The composition of the team depends on the goals and structure of the project.

Monofunctional team — this is a group of specialists, each responsible for their narrow area (for example, only backend developers or only frontend). This approach can be effective for large projects with clearly divided areas of responsibility.

Cross-functional team includes specialists from different areas (backend, frontend, testing, design, etc.) who work together on a functionality or product. This promotes closer interaction, quick communication, and more flexible development.

In my experience, cross-functional teams were used more often, as they allow for faster response to changing requirements and ensure higher quality component integration. However, the choice depends on the specifics of the project and the organizational structure of the company.
