What If You Make A Mistake At Work?

1) Acknowledge that you messed up because it is human to error. 
2) Investigate as to why you made the mistake. 
3) Analyze how you can prevent the same from occurring again.
4) Make amends immediately by taking quick action and keeping your seniors informed.
5) If your colleagues, clients or bosses were harmed due to your follies, it is very important that you apologise to them graciously.
