How do you handle the lack of sufficient information to complete a task?

If there is not enough information to complete the task, I usually follow this plan:

1. Task analysis — try to understand exactly what is required and what data is already available.
2. Information search — study documentation, specifications, previous solutions, related tasks.
3. Consult colleagues or supervisor — ask clarifying questions to obtain missing details.
4. Break down the task into subtasks — sometimes helps to identify what information needs to be gathered first.
5. Prototyping or experimentation — if possible, conduct a small experiment to test hypotheses.

This approach helps minimize risks and improve the quality of the solution even when initial data is lacking.
