The business delivers a feature that could break existing logic. How do you communicate the risks and what do you suggest?

To communicate the risks to the business when implementing a feature that could break existing logic, it is important to:

• Clearly describe which parts of the system may be affected and how.
• Assess potential consequences: bugs, data loss, deterioration of user experience.
• Propose risk mitigation options: for example, phased implementation, feature toggle, additional testing.
• Recommend creating backups and a rollback plan.
• Suggest conducting load and integration testing.

Thus, the business gains an understanding of the risks and options for managing them, which helps in making an informed decision.
