Have there been cases where requirements changed after development had already started? How did you act?

Changes in requirements after the start of development are common. In such cases, it is important to:

• Assess the impact of changes on timelines and resources.
• Discuss priorities and possible compromises with the customer.
• Update documentation and the project plan.
• Implement flexible methodologies (e.g., Agile) to adapt more quickly.

For example, if the customer adds a new feature, it can be allocated to a separate sprint or release to avoid disrupting the current schedule.
