Hi,
Any Qlik Sense application you use can be infinitely changed and expanded.
To add new data sources, you need to change the script code and reload all the data.
In order to get new information from already connected data sources, you just need to download new information by running the application script.
After any reboot, all visual images are automatically recalculated.
The usefulness of using Qlik Sense/QlikView is determined by the degree of novelty of information that management receives to support decision making. In large organizations, there is always the problem of analyzing data from disparate sources. In small organizations, management better perceives the numbers and the state of the business without any calculations, so it is much more difficult to justify the necessity of using Qlik Sense/QlikView.
In any case, the main thing is the degree of novelty of information obtained on the basis of visualization Qlik Sense/QlikView. It is necessary to search for the answer to the question: what will management receive in exchange (how much does this information cost for business) in comparison with the costs of using Qlik Sense/QlikView? If the cost of information on the basis of visualizations is higher than the cost of using Qlik Sense/QlikView, the question of expediency will disappear by itself.
This is just my personal opinion.

Andrey
