Here is how to create personalised dashboard home page for each member of your organisation.
First, as administrator I will create 3 additional menus and add dashboards to each menu.
In order to achieve it, I have to create Site Map for these dashboards here
Then I added menu items to it
Then I just added dashboards to these elements.
And the last step would be to make respective screens available to only certain users and make it Home page for them.
All the best,
