When there is a handover of a Qlikview project from one developer to the next it is highly recommended to add some documentation about the project. The Documentation Module exists out of a check listwith the questions a developer could ask after taking over a project and an excel template which provides a structure on how to document a Qlikview app. Some example questions that should be documented are:
What is the business case - goal of the app?
What is the description of each table in the datamodel of the app?
