I like the idea of this home page but choice of whar is displayed by default is paramount. We want to keep our intranet home page as the default. A switch coming next year to control it.
Releasing this before the option is available and changing the experience for users is not an acceptable experience. Customers have spent a lot of time currating their intranets to maximise the experience for their people. Having an extra layer to go through before you get to it is an extra click we don't need.
Also the navigation containing links to Viva experiences needs to be customisable. Organisations need to have the options as to when they want to implement Viva. This feels more like a marketing / advertising push than a benefit to customers. Any sort of home navigation needs to be customisable.
