Because Data Management is my profession
But I can’t understand why some organizations
still have data problems like this:
First name Dmitry
Second name Kovalchuk
...
Such bad data can act as
the butterfly effect
If I had the so many errors in my address book
She would not have received my letter
They would not have been born
I would not be so happy…
and it works!
Fortunately there is the Master Data Effect
So manage your data well
and make yourself happier!

My master data effect

151

Published on

I created this presentation after a conversation with my younger daughter. She asked me to talk about my job: Why is it so important and interesting? Why do I sometimes work on weekends? Why am I always working with so much data…

So I told her that children who do poorly in school become error-prone and lazy. Which of course results in lots of errors. And sometimes those errors can lead to serious consequences.

My little daughter said that her grandmother had two birthdays in one year by mistake — and that it was great! My mother-in-law actually does have two birthdays: one is her true birth date, and the other is her birth date according to her USSR passport.

I think our attitude on data is shaped by our culture and behavior patterns. So we have to inspire our children (and ourselves) to be more accurate with data — because it can influence our lives significantly and adversely when it’s no longer trustworthy.
