Keeping stakeholders calm while fixing a problem

I had to update a worried stakeholder yesterday.

A bug appeared in the live system.

They heard about it and were anxious.

I sent a quick update for you email.

I explained we found the issue.

I said we expect it back by tomorrow noon.

I did not promise more than I knew.

I just gave facts and a clear timeline.

I ended with: I will let you know the moment it is resolved.

That simple line made them feel heard.

It also set a clear next step.

They replied with thanks and patience.
