We are operating under the assumption that people taking the online assessment are contemplating an implemntation of Hadoop. Some have zero experience with Hadoop while others have completed a proof-of-concept project with Hadoop but need additional guidance before proceeding with a production implementation. Indeed, at TDWI we regularly communicate with a wide range of people and work with organizations that are considering Hadoop as part of their solutions for big data, advanced analytics, data warehouse modernization, data exploration, and so on. They all have questions about where to focus their best efforts with Hadoop, and the guide and tool for Hadoop Readiness Assessment provide answers for many of these questions.
