Have you ever been assigned a task previously performed by a colleague?

Yes, such situations are quite common. When I am assigned a task that was previously performed by a colleague, I usually:

• Study the existing code and documentation to understand the logic and architecture.
• Communicate with the colleague, if possible, to get advice and nuances.
• Conduct testing to ensure the correctness of the work.
• Gradually make changes or continue developing the task, maintaining the style and standards of the project.

This approach helps to quickly understand the task and avoid mistakes when transferring responsibility.
