This article draws your attention to the design, devel­opment, deployment, and refinement of cognitive computing systems (CCSs). While CCSs are deployed in a variety of fields yielding benefits exceeding expectations, there are also major failures. Lack of appreciation for the differences inherent in developing a CCS versus a traditional software system is key to these failures. To assist in developing successful CCSs and to derive benefits from them, the authors offer a set of nine key recommendations based on their examination of over two dozen systems. They conclude that CCSs will be a dominant technol­ogy that will permeate all business operations for the foreseeable future.
