Tableau: What was one of your biggest challenges before Tableau?
Simon Wong, Head of Business Intelligence: The size of the data set was one of the biggest concerns for us as an organization, as the organization grows, you realize that the data itself becomes much greater.
Tableau: How did Tableau help you overcome that challenge?
Simon: Being able to visualize it in a way that's much more simple, that's much more acceptable. I know exactly what message I can take out from this data set, and that was very important for us.
Putting Tableau in front was one of the first things that we had done to unite a lot of these business units in different countries and regions to use the same data set and also the same source of truth going forward, for our company as a whole.
Tableau: How did you manage the changes?
Simon: Instead of working parallel with the business, we wanted to actually use this data to run in the business, so using that insights to make data-driven decisions, one big play.
Tableau: How does having a single source of truth affect your business?
Simon: Single source of truth is a very important goal when it comes to analytics. When we do our forecasting, when we're looking at, for example, a churn analysis and from a churn perspective, then you can do a proper analytical forecast model. Let's say the next five or six years for our profit and loss statement (P&L), we should be able to do that without any problems. Having that single source of truth is very critical in running our business—our global business.
