How independent is the team in decision-making, and who is the final Decision Maker?

The degree of independence of the team in decision-making depends on the organizational structure and culture of the company. Usually, the team can make technical decisions within their competence and the project, but key strategic or architectural decisions are approved by the project manager, architect, or product manager — they are the final Decision Makers.

For example, the team can independently choose tools for implementing a task, but if it affects the overall architecture or budget, the decision is made by the manager.
