do want to have project timeline/task tracking app?
do you wanted to prepare the task effort/activity for end to end implementation like below task?
source identification (table, dimension, fact, external source, etc)
prepare mock using excel based on BRD and the get sign off from users end
Development (import source,data loading, star schema model design, app (charts, kpi etc)
testing on developed app, UAT & UAT testing, tech doc(User guide, Tech/functional spec etc ) and production implementation & support etc)
PS: also check this thread (the timeline estimation depends on your user requirement only we can define.
There is Qlikview to sense conversion tool there @ dev hub it will migrate your app and chart object (some object may not support that one u have to re-create it)
