Here’s an overly simplistic statement but generally good rule of thumb about IT in government: Systems integrators are a symptom of poor systems architecture. This is to say that today’s systems integrators, the people governments ask to create software that (usually) enables us to extract data from one software system and then restructure it or create processes around it so that it can be shared with another software system, are being asked to do work that shouldn’t exist. They are symptomatic of a failure to realize that any large IT system could and likely will need to be a platform. They also are a window into a massive opportunity to reduce spending on government IT systems.
