In my last post, I started to talk about the free Analysis Platform application used by Denso and others (especially in Japan) to tackle big data.

A lot of problem solving is about understanding the current situation. Ideally this includes data. There are a couple of ways to analyze data. Denso uses seven traditional ways of analyzing data, which you are all familiar with. However, they expanded these tools with the goal to analyze big data. They call it the Digital Native Seven Quality Control Tools (DN7 or DN7QC7) …and of course I will share this with you.
