You don't give management all of the information they need as it creates a reporting burden for no reason. They don't know how difficult the reports are to use and they won't use a dashboard because that means they have to think about the dashboard instead of the decisions they are trying to make.
If you have management that wants reports, you ask them what they need to decide on and then you ensure that they will get *that* information without all the fluff. It doesn't matter whether or not anyone here thinks if dashboards vs reports are relevant, is it relevant to the user of the data? Unlike sales dashboards where management knows what they are looking for, they have now idea what technology articles they need, so until that day arrives, reports based on what decisions they have to make, are.
And that is what you have to say.
