How often did it happen that you did not meet the deadline?

Yes, there have been cases where estimates were not met. Usually, this happened due to:

• Underestimating the complexity of the task or the volume of work.
• Not accounting for external factors, such as changes in requirements or technical issues.
• Insufficient experience in estimating similar tasks.

In such situations, it is important to analyze the causes, adjust the estimation process, add time buffers, and improve communication with the team and the client to minimize the risks of estimate discrepancies.
