Tableau: How large is the data you work with, and in what formats or systems?
Mr. Kuroki: Currently, we work on a couple of million rows of data, we would like to take care of tens of millions of rows of data. We use various data formats such as Oracle, Excel and Access. For example, when we don’t have enough system data for necessary analysis we fill in the gaps with data using Excel and "blend" it all and use it.
Tableau: Was there a particular problem you were facing?
Mr. Kuroki: The work environment of each company structure is varied, so we have carried on conducting necessary analysis in a timely fashion with each organization utilizing Tableau, so that we can provide analysis in a timely fashion that matches the work environment.
In the past, the IT department used to listen to the requests of user departments and offered to develop reports. But with that, we couldn’t avoid taking too much time before providing reports and had problems answering the detailed analysis needs.
Tableau: What does Tableau allow you to do?
Mr. Kuroki: Up until now, both data managed in the system and individually managed data at each organization was monitored individually, but Tableau made it all in one to allow for easy monitoring. Also, fixing how the report looks in detail and adding contents are done quickly by user department staff and this is the effect we can see. From these things, we have been working on it hoping to accelerate the PDCA cycle of companies and each organization.
Tableau: What are the most important benefits for you from Tableau Server?
Mr. Kuroki: The biggest merit of using the Tableau Server is being able to securely share reports in a timely fashion, I believe.
Tableau: How did your implementation start?
Mr. Kuroki: For introducing Tableau, the introduction methodology regarding self-service BI named Tableau Drive is a good reference, I think. Based on that, we are working in four divided phases. Grasp the current condition first, organize the future structure, do plot typing and sort the base of development for the company and develop it in actual companies, that’s the flow.
We incorporated the know-how that was gained in the development as an additional element in Tableau Drive and we are managing it as our own unique methodology now. We have been utilizing it for other companies’ Tableau introductions as well.
