Lego blocks allow the average person to build practically anything, because they come in standard sizes, and interconnect with ease.
Having built a model, one may later take it apart and reuse the standard blocks to build other models. One may do this time and again, giving hours of enjoyment.
By contrast, few people have the skill to carve models from wood.
Once carved, it is practically impossible to ‘remodel’, and completely impossible to reuse any of the parts for other than firewood.
What has the above ‘common sense’ got to do with data quality?
Imagine trying to build a lego model using partially moulded lego blocks? Imagine opening your lego model kit to discover that some of the pieces were missing. Truly unimaginable.
We in the Data Quality Profession need to educate both Business and IT on the need to create “standard data components”, that can be easily interconnected to satisfy the information requirements of the business.
Currently, the focus of the Data Quality Industry is on data “Fixing” – remoulding data into parts that are more complete, and more useable. I see this continuing for a long time, due to the vast quantity of legacy data. I see the focus moving more towards “get it right first time’ with the emphasis on creating completely moulded, standard component parts from the outset.
