I've found that the vast majority of stakeholders want a dashboard either to (1) spend other people's money and feel important or (2) create opportunities for multiple "version of the truth" and thus prepare multiple narratives to pick and personally gain from when needed. Middle managers would rather reserve the right to say X dashboard has a metric that doesn't reconcile with Y other reliable source, than to actually collaborate with competent analysts and build a holistic info platform. We need to stop casting such a wide net and selling the dream of a glamorous all-knowing BI tool and instead, service analytics on a case by case basis. Over time this can inform practical dashboard design, kept up by a small team of experts and largely ignoring the "laundry lists" of every prospective user.
