You have to bring in data from different sources, maybe even different companies in a merger due diligence scenario for example and the agreements and sources of data are constantly changing. Do you have experience with using tools like Tableau in those situations? I've never been exposed to Tableau besides at a very superficial level, but it seems to me that these solutions are great when you can link them to consistent sources of data and rules, but the more inputs and variables are changing the harder it would . Thoughts?
