Information architecture (IA) is a cornerstone of enterprise architecture (EA), but 43% of the architects we surveyed either have not yet addressed this domain or have only begun to implement what they need. And for the vast majority of the established IA programs, the most substantial portion of the value they expect to deliver is still in the future. IA has been EA's problem child, but demands for high-quality real-time information and advances in information management software that provide significant new business capabilities — but entail "garbage in, garbage out" scenarios — mean architects can't afford to delay its implementation any longer.
