How do you assess your responsibility when working with legacy or inherited code?

Working with legacy or inherited code requires a high level of responsibility, as such code sections often contain critical business logic and may be poorly documented.

Approaches to responsibility when working with such code:

• Carefully study the existing code without making hasty changes.
• Write tests (unit/integration) to capture the current behavior before refactoring.
• Perform refactoring gradually, improving readability and maintainability.
• Document changes and reasons so that the team understands the logic.
• Communicate with colleagues who may know the history of the code.

Thus, responsibility manifests in accuracy, thorough analysis, and ensuring application stability when working with inherited code.
