This situation suited us for a while, but …
Our attitude to data quality changed
when we became interested in girls

We needed their contact details to call them and send post cards
Teacher

And we managed to get them!

It was master data = single version of the truthI know that NOW…
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
Phone (701) 527-3065
Country Russia
AddressAstana
Tax number 66002341
Marital status Single

They have mistakes
I am Dmitrii now ((
Are no longer timely I live in Kazakhstan
Are inconsistentIt is my passport number
Are incomplete My address is 5b Sarayshyk str., 5
Are error-prone and unverifiedI’m married
Have different formats
It is +7 701 5273065
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!
It makes a difference->
