"Without data, you are just another person with an opinion". How can we use data to help us test our product better and be more efficient? In this lecture, we'll discuss the use of BI in testing, implementing BI using Google Analytics or an internal company BI system, TPAs (Anodot, Grafana, TrackJS), and making smart decisions using data.

23. 3 ways to get BI into your testing
1. Google Analytics
2. Internal tools
3. TPAs

24. Google Analytics
SETUP
Get the tracking number e.g., UA-XXXXX-Y and add the
code
<!-- Google Analytics -->
<script>
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','https://www.google-analytics.com/analytics.js','ga');
ga('create', 'UA-XXXXX-Y', 'auto');
ga('send', 'pageview');
</script>
<!-- End Google Analytics -->
downloads
analytics.js
allows you to
schedule commands
to be run

25. Google Analytics
ADD EVENTS
Event hits are sent by using the Send command and specifying a hitType
<button id="addButton"> Click me </button>
<script type="text/javascript">
const button = document.getElementById('addButton')
button.addEventListener('click',function (e) {
ga('send', {
hitType: 'event',
eventCategory: 'buttonClick',
eventAction: 'mainButtonClick',
eventLabel: 'nameOfThePage'
});
});
</script>

26. Google
Analytics
▪ Page tracking
▪ Event tracking (user interactions)
▪ Social interactions
▪ User timing
▪ Error tracking

27. Example
Mobile
devices

28. Example
Users’
common
flows

29. Without big data analytics,
companies are blind and
deaf, wandering out
onto the web like
deer on a freeway. Geoffrey Moore,
partner at MDV

30. Google
Analytics
▪ It’s free
▪ Big community
▪ Fast integration
▪ Custom reports
- upgrading is $150,000
- may be overwhelming

31. Internal
BI Tools
▪ Tailored events
▪ Track history or real-time
▪ Trends AND users

32. Catalog
for all Wix
BI events

33. User
explorer
(history)

34. User

(real-time)

35. Quix (stored
/ custom
queries)

36. Internal
BI Tools
▪ Flexible & scalable
▪ TPAs Integration
▪ Single user flows
▪ Time frames
- Takes time to
develop and
define

37. TPAs
▪ Anomaly detection
▪ Reports
▪ Automatic notifications
▪ Server-side status
▪ Client-side status

3. Dev teams looking for

4. Rollback/ closing new

5. Fix issue and GA
6. Back to normal

43. Grafana

46. BI focuses
you on the
right things
to test.
As part of any
feature
development, you
should rely on BI
data to make better
decisions.
