My thought on Data after 3 years diving into it.

1. Embrace data -
the easy said-than-done path
L3 - VNG

2. wrong lane…
dangerous…
too much for a woman…
…20kg?

3. Confirmation Bias : You tend to learn/see what you already know

4. Data
Information/
Insight
Action
VNG/Game Industry : cruel world with/without data
rule of thumb

5. “Dear Mr CEO, we’ve got 5B revenue in the 1st month.
Let’s rock… We want to have a 5* pool-party!”
“Dear Mr CEO, we’ve got 6B revenue in the 1st month.
We burn 400K till now (ongoing ROI ~ 75%) and users
keep paying. Let’s watch…”
“Dear Mr CEO, we’ve got 6B revenue in the 1st month.
We burn 400K till now (ongoing ROI ~ 75%) to fill up 10
servers. Rev from server 1-3 is 5B and users don’t have
any content to consume. Plus, retention 7 from server
4-10 is quite low (5%). Let’s stop asap until we get the
hot-fix in our hand.”

Replace “server” with “restaurant, hotel, website…”

Tech Stack Google Apps Script

18. Why we buy less?
Less Installs, more effective users, higher retention,
better ROAS/ROI

19. My recommendation
Practise!

20. My recommendation
Practise!
Keep asking WHY…
Learn a program language… (Excel VBA,
Google Apps Script, R, Python…)
Reading (our) books : cleaning data, visualize data …
Leave your job to find a data-driven company
Think inside the box & Find the opposite

21. You can live without data!
You can die fast without data too!
