Qlik Sense has given us visibility into our data to make informed decisions. We are able to compile data for insights into metrics that we had not seen before on a large scale. Perhaps only one or two users were still getting their insights of data compiled into an Excel spreadsheet.
I wish the product had the ability for slightly more customization. The out-of-the box charts and visualizations are fantastic, but I want to be able to tweak it without having to add outside extensions and widgets.
