- Provide access to the level of comprehensive, consistent, clean and current data that the business needs for analysis – and is willing to pay for.
- Systematically implement and support data governance processes.
- Separate data integration from BI reporting and analysis processes.
- Implement the staging of data from systems of record through a data warehouse to data marts or cubes – i.e., a hub-and-spoke approach.

- Create a “live” data and reporting dictionary that business users can use while accessing reports or as a table of contents (with definitions) for the data available to them.
You will be able to design a high-level BI architecture early in your project, but it later will need to be designed in greater detail and built out incrementally and iteratively if you are going to provide a robust BI environment.
Note: Don’t believe vendor “marketectures” that promise you an integrated and robust BI architecture simply by installing their software. Set realistic expectations, both for the business and IT. Implementing a successful BI architecture is a journey, not a one-time event.
