Fuzzy Single Point of Truth Concept
It’s a kind of mantra for business intelligence vendors. “With business intelligence technology you’ll get single point of truth”. “You’ll not have any more problems and doubts about figures, which figure is correct.”
This is a nice idea but this is also a fairy tale for business people with too much money.
Company information needs are enormous and this would mean that company needs many single point of truth from the Information Systems. At the certain point, single point of view_id1 will look very similar to single point of truth_id2. What is our truth that we need, id1 or id2?
There are no systems on Earth that can provide copy/paste figure from business intelligence or any other reporting information systems unless somebody deeply filtered and processed all information and prepared reports. And this is not done by a system but by a business and financial analytics. Somebody needs to prepare it and this is core information knowledge.
Why is knowledge about designing of single point of truth so important? It is the methodology and definition issue more then IT issue. Companies need permanently more and more information. Any future change in information demands will be costly charged because company does not know own information basis. In addition, if company does not know how single point of truth is made, how can it guarantee quality of official reports?
Companies need to know their information basis in details and should not be afraid to use it. Companies should not outsource preparation of single point of truth to somebody else because needed knowledge will reside out of the company. Methodology about how information are designed and why will stay out of company or at the wrong place.
