I'd say it's two-part problem: (1) Specification (2) Implementation Specification has always been the primary problem, the simple reason being that we are trying to quantify human desires regarding information flow. As we are finding out, it's non-trivial to say the least. This goes back to an earlier talk I learned about here and watched just this morning by the outstanding MIT professor Nancy Leveson, https://www.youtube.com/watch?v=WBktiCyPLo4 https://www.youtube.com/watch?v=WBktiCyPLo4, who has analyzed various engineering problems (including the Challenger disaster) and even published an entirely new methodology for analyzing large-scale systems. Her book can be downloaded for free at http://sunnyday.mit.edu/safer-world.pdf http://sunnyday.mit.edu/safer-world.pdf. Of course, economics factors into everything people endeavor to do these days, but strictly within the domain of creating correct information management systems -- from a purely technical level -- the problems are specification and implementation, in that order. Getting someone to pay for the time and team needed to do the job correctly is a completely different story, and not a pleasant one, it seems.
