Have there been cases where the wording in the technical specifications was very vague, but something needed to be done and there was no one to ask?

Yes, such situations are common. When the specifications in the technical assignment are very vague, and it is impossible to clarify with the customer or analyst, you can:

• Rely on common sense and experience, choosing the most logical and safe solution.
• Make an assumption and document it in code comments or in the documentation, so it is clear later why this particular decision was made.
• Use approaches that minimize risks, for example, implement functionality in a way that it can be easily modified or extended.
• When possible, create a prototype or demo and show it to interested parties to get feedback.

This approach helps to move forward without blocking the process due to uncertainties, and preserves the possibility of adjustments in the future.
