Some thoughts of your typical data shepherd / data plumber / data dance teacher sort of person.
What's so hard about making mistakes for me? The embarrassment of it, maybe I did not know something, or yes that thing that I did well, yes, I did know better. It's not easy for me to admit mistakes. Just ask my long-suffering partner (thank goodness, she does not read my blog!). Yes, I do like to be right and do it the right way. Admitting that I was wrong, or did something stupid, takes it out of me, it's not easy.
Hopefully, in my professional life, I am a little better at dealing with my mistakes. A few years ago, one of my jobs was with a large consultancy company. I was the person responsible for producing reports for the service desk. From time to time there were errors with the reports that I was responsible for producing. During that time, I developed a strategy which I still use to deal with mistakes.
1) Take responsibility
It's not easy to put your hand to say you have made a mistake. On the other hand, how to do you learn from mistakes? For me, part of growing is learning to take the bad with the good. Also personally speaking I have more respect for someone who has what it takes to say when they have made a mistake. Even if you have not made the mistake you find, then take make it your responsibility to fix that mistake. If I do this then my primary focus is to get the issue resolved and move on. Finger pointing or the blaming someone is not part of this.
2) Find the challenge
What when wrong? How did it happen? Be able to explain what happened, in simple non-technical language that anyone can understand. Also be confident that you can explain in technical terms to your peers.
3) Fix it
Get your hands dirty, get involved in fixing the issue. Help find a solution to rectify the challenge or work with the people fixing the challenge if you can. For me, I have and do still learn so much just from fixing mistakes.
4) Prevent it!
Better to have a fence at the cliff edge than a hospital at the bottom. What will stop it happening the mistake happening again? An extra check of something, a checklist of things to do in the same situation.
Is there something I missed, do you have a different strategy. Maybe you disagree? Let me know, every day is school day for me :-)
