Your Challenge

  • Data warehouse implementation is a costly and complex undertaking, and can end up not serving the business' needs appropriately.
  • Too heavy a focus on technology creates a data warehouse that isn’t sustainable and ends up with poor adoption.
  • Emerging data sources and technologies add complexity to how the appropriate data is made available to business users.

Our Advice

Critical Insight

  • A data warehouse is a project; but successful data warehousing is a program. An effective data warehouse requires planning beyond the technology implementation.
  • Governance, not technology needs to be the core support system for enabling a data warehouse program.
  • Understand business processes at the operational, tactical, and ad hoc levels to ensure a fit-for-purpose DW is built.

Impact and Result

  • Leverage an approach that focuses on constructing a data warehouse foundation that is able to address a combination of operational, tactical, and ad hoc business needs.
  • Invest time and effort to put together pre-project governance to inform and provide guidance to your data warehouse implementation.
  • Develop “Rosetta Stone” views of your data assets to facilitate data modeling.
  • Select the most suitable architecture pattern to ensure the data warehouse is “built right” at the very beginning.
