Who played a key role in choosing the technical and organizational strategies at your previous workplace?

The key roles in choosing technical and organizational strategies usually include:

• Tech Lead — responsible for the technical side, architecture choices, technologies, and standards.
• Architect — shapes the overall system architecture and defines technical directions.
• Project Manager — responsible for organizational aspects, deadlines, and resources.
• Development Team — sometimes participates in discussions and decision-making.

Depending on the company and project, responsibilities may be distributed differently, but most often, it is the Tech Lead and architect who make the key technical decisions.
