What method of interaction in a team do you consider most effective?

The most effective way of team interaction I consider to be the combination of the following practices:

• Regular meetings (stand-up, planning, retrospective) for synchronization and discussion of current tasks.
• Using version control systems (e.g., Git) with clear branching rules and code review.
• Transparent communication through messengers and task trackers (Jira, Trello) so everyone is aware of the progress.
• Pair programming and code review to improve code quality and knowledge sharing.

This approach helps minimize misunderstandings and accelerates collaborative work on the project.
