What is the typical size of a team involved in a project?

The size of the team involved in project implementation heavily depends on the scale and complexity of the project. For small projects, it can be from 2 to 5 people, including developers, testers, and a manager. Medium projects typically require a team of 5-10 people. In large projects, teams can number dozens of specialists, divided into sub-teams based on functionality or architectural layers. It is important to note that team efficiency does not always increase with its size — a very large team can lead to communication and management difficulties.
