Business Intelligence software promises us this and make this seem like an achievable goal. And yes it would be great to know everything about everything and get a perfect 360 degree view of the organization.
Yet it is not really achievable, actually not even close. Instead ask what are the goals & objectives of the organization, and how does this support that end. We are very quick to say "we can do that" but we need to temper that with "why should we do that?" Think of the goal of a dashboard - to provide real-time information on a specific subject. I have known many managers that constantly stare at the screen to see if anything moved.
What we really need is to understand how to use the function of time and integrate that into a analytical management process. What would you get more out of, a tactical dial that shows us one KPI, or a meeting at the end of the day to review a number of KPIs?
