Zynga : Stratégie « Massive Analytics »
Interview Ken Rudin, Director of Analytics for Zynga Games
"I've been in the large data world for a long, long time,"
"I absolutely love the technical challenge when you get
into massive skyscraper-size chunks of data. Plus, I love
even more the business value you can get out of having that much data…
If you know what questions to ask, you can get some phenomenal answers."
Obtenir des réponses = Créer de la valeur
“Where analytics fails in most companies is not the science,
it's the communication of the results.
Before Tableau, there were a lot of tables and numbers,
but it's very hard to communicate those results.”
Communiquer = Partager
Et encore
We were looking for something that would address two needs.
First, give us a visual way to communicate.
Particularly with numbers, people are much better
at understanding data when it's presented visually versus as letters and numbers.
We wanted something that was great at that.
Second, we wanted something with interactive capabilities
so we could look at the data and say,
"Why is there a bump there? Why is there a dip there?"
and then drill into it and come up with an "Aha, that's why"
moment. We didn't have that capability before.
Sur les Utilisateurs:
There are two types of users here
The producers actually create the dashboards and the analyses –
there are a couple of dozen people right now doing that.
The consumers -- that's a very large number.
A very high percentage of our employees are consuming the information
via dashboards and portals every day.
Une seule solution pour tous
Answering unplanned questions
We launch new games all the time; we want to look at the impact
of each new game on our business overall.
Let's say you're playing FarmVille right now and we introduce Game X.
It quickly gets a lot of players, and we want to look at where those players
came from. How many of them were new to Zynga?
How many of them play FarmVille and now also play Game X?
How many of them used to play FarmVille, have stopped playing
and now only play Game X -- meaning we cannibalized our own user base?
How does that trend over time?
How does that compare to other games we've introduced?
We also want to slice and dice player demographics.
How many of them are playing every day?
Three to five times a week? Once a week only? How is that changing over time?
