Pointing the finger is a no-no if you make a mistake, especially if it's a serious one. This doesn't solve the problem and we all know that the truth will come out, sooner or later, whether we like it or not. So why not be responsible and own up to your mistakes? This will make the identification of the root cause of the problem faster and therefore be able to come up with a resolution faster too. Nobody's perfect and we all make mistakes but when there comes a time that we make a serious one, it would be good to follow these simple steps. As hard as it may seem, own up and admit responsibility for the mistake. This is the first thing that we must do. Let everyone that needs to be informed, know about your serious mistake. When communicating with them, you need to show remorse and be sorry that you've made that mistake. Pointing fingers and making excuses are a definite no-no so you should only stick with the facts. Look for resolutions to the problem and implement them. When all has been resolved, work into preventing this mistake from happening again. Move on and don't carry this mistake with you all the time. Remember that what we do after we make the mistake is more important than the mistake we've made.
