How was the size of the backend team determined in the project?

The size of the backend team in a project is usually determined based on several factors:

• Scope and complexity of the project. The more functionality and integrations, the more specialists are required.
• Implementation deadlines. If the project needs to be completed quickly, more developers may be needed.
• Technical requirements. For example, the need to support high load, scalability, security.
• Experience and qualifications of the team. More experienced developers can complete tasks faster, which affects the team size.
• Project budget. Financial constraints influence the size of the team.

Often, the estimation of team size uses the man-month calculation method, based on the assessment of task complexity. For example, if 120 man-hours are needed for the backend, and the work is planned for 3 months, then 1-2 developers can be taken depending on workload and task parallelism.
