IMHO it often proves to be a better approach when you add the classical Qlik intro tab to your document or give your end-users the 3-minute training (in group), and you write a slightly longer document that introduces the bussiness logic and analysis techniques in this particular BI document. The creation of such an introduction can often be delegated to the (key-)user that has been involved in the creation/design/development/testing of the QVW-document.
The old intro tab looks like this. It has one exceptional advantage: initially, the right side is completely empty. You add live fields and charts from your document so that they can play with the real stuff...
