Your company generates lots of data, but the  business outcomes you gain from that data can  

play00:06

be largely affected by data quality. To use  an analogy, imagine you're a chef and you have  

play00:13

the highest accolades in the industry, a highly  experienced team, but when the ingredients come  

play00:18

in, those are poor quality ingredients. Picture  rotten tomatoes, rotten onions. So when you go  

play00:23

and make those entrees, the end result is poor  quality and your restaurant reputation suffers.  

play00:29

This is the same impact that poor data quality  can have on your business, causing your company's  

play00:34

reputation to suffer as a result. There are a lot  of different factors that can impact data quality,  

play00:39

such as the number of sources or the size of  your company. But today, I want to talk about  

play00:44

four main qualities within data itself. Accuracy,  completeness, consistency and uniqueness. And I'm  

play00:52

going to talk about them through the lens of a  lead generation company. Starting with accuracy.  

play00:59

Accuracy is about the current state of your data  versus reality. So for my lead generation company,  

play01:06

imagine I'm driving traffic to a website and all  of a sudden I get a sudden spike in usage from  

play01:14

bots that had the click generation. If I don't  account for this spike when I go and pull that  

play01:19

data, at the end of the day, it's not going to  reflect reality, so it's not going to be accurate.  

play01:25

Next, I want to talk about completeness,  which is about how you have filled out all the  

play01:31

required fields in your dataset. So let's say I'm  launching a survey campaign. And I'm collecting  

play01:40

names and email addresses, but I don't require  this field. So when I go and pull that data,  

play01:46

I notice that some of my participants didn't put  their name, Some of my participants didn't put  

play01:51

their email. So when I go and pull that picture of  the client of the customer, I have an incomplete  

play01:56

dataset and incomplete picture. Next we talk about  consistency, which is about how uniform your data  

play02:05

set is throughout different data sources. So  back to my lead generation example. Let's say  

play02:12

I'm driving traffic for a Dropshipping campaign  and I have my procurement team collecting zip  

play02:18

codes and my marketing team collecting zip codes,  but my procurement team is looking at them in  

play02:25

a five digit format while my marketing team  is collecting them in a nine digit format.  

play02:32

When I go tap into both of these  databases and pull the customer profile,  

play02:36

it might be incomplete because those zip codes  don't match up throughout my systems. And lastly,  

play02:43

there's uniqueness, which is largely tied to  the number of duplicates I have in a dataset.  

play02:53

So in my lead generation context, you can imagine  having 50,000 leads at the end of the year.  

play03:01

But when I actually go into those leads, I realize  that 20% our duplicates from customers who filled  

play03:08

out the information previously. So now when I go  and pull that report, I actually have 20% less  

play03:13

data and a lot less positive looking picture  for my company. So looking at these aspects,  

play03:21

it's easy to think, Wow, there's a lot of manual  inspection here. How can I go through all of  

play03:25

my data and understand these resources, these  qualities? Right. Well, you can actually leverage  

play03:31

machine learning and AI to automatically sense  these key features as data enters your system,  

play03:37

saving you time and manual inspection. If you're  curious about these features, check out the links
