Why fail? Think for positive. Look up the project performance report. Try to find the lags & root cause.
If the failure is a value realization, it could be project-related. Maybe the wrong thing was delivered. Maybe there isn't an actual demand for what was delivered (been there). In my experience, coming up with a unified health record has problems in scope, support from the intended recipients (demand vs privacy concerns), competing interests, standards that are understood (HL7 is getting better, from what I've heard), budget concerns (small providers needing new or upgraded systems), companies attempting to monetize the UHR into exchanges that providers have to subscribe to (also affects small providers).
