Hi, Qlik Learn.
There is no one specific answer for this question. If you search on the internet for Project or process lifecycle there are many possible options. I don't think QlikView advocates any one in particular. Often it is driven by the standard practices within the organisation you are working in.
However, I must add that QlikView does lend itself to close participation by the User. Requirements can be turned around very quickly and shown back to the user for more input.
Regards,
Neil
