What do you advise the team if it is difficult or impossible to determine project deadlines?

If it is difficult or impossible to determine the project deadlines, I would advise the team to:

• Break the project into smaller, manageable tasks or stages with clear completion criteria.
• Use an iterative approach (e.g., Agile) to regularly receive feedback and adjust the plan.
• Estimate tasks based on relative complexity or use techniques such as Planning Poker.
• Constantly communicate with the client or stakeholders to clarify priorities and expectations.
• Focus on a minimally viable product (MVP) to get a working version faster.

This approach will help reduce uncertainty and increase transparency in the development process.
