Should You Build BI Before You Clean Your Data?
Implementing a business intelligence environment against data you don't trust? Sounds counter-intuitive, some would say: ‘just plain wrong.' How could you possibly build a data warehouse and cubes on data that might not be accurate? You shouldn't of course, and that is the point. Accurate data is the non-negotiable cornerstone of any BI effort.
But accurate data does not happen by itself. Data needs to be enthusiastically governed to a state of truth and reliability, and this is a big job. So big in fact, that attempting a global data governance initiative can cost so much time and energy as to obliterate the initiatives it was designed to support in the first place.
