A small 'encore'..the fifth quadrant.
Where quadrant I and quadrant II are (simplistically stated) degrees of order and quadrant III and IV are degrees of un-order, there is a fifth quadrant. The quadrant of disorder.
This quadrant comes into play when one does not have a glue what to do, where they are and what decision to make. If you are not aware that you are in a disorderly state, you will fall back to your comfort-level. Do the stuff you always did....
- Data scientists (quadrant IV) need to write down their 'requirements' because somebody needs to make a data-mart....
- Regulatory compliance reports (quadrant II) to authorities are comprised of non-validated, non-consistent excel-worksheets (quadrant III)....
- Nah, data governance did not work with us very well....
- Data scientists (quadrant IV) need to deploy changes from development, test, acceptance to production...
- Lets hire 12 ETL developers.....
- This data we are receiving is so bad, lets model it....
- Data scientists (quadrant IV) are not allowed to use data from quadrant I, because it might compromise the reliability of the systems...
- The BICC need to improve the data quality, we can't use it...
- We need a datalake for our management information, or (even worse) for our regulatory compliance reports....
- We need data virtualisation (or any other <tech>)....
- Yes, we dimensionally model everything...it always works!
- Yes, we use data vault for all our data....it always works! ;-)
Sounds familiar?
If you are in a disorderly state regarding the data domain, no problem! Form a team with people from all the different quadrants, discuss....
It's ok to start with a quadrant III to IV project!
It's ok to start with a quadrant I to IV project!
Remember; the Data Quadrant Model is not imposing any values.There is no right or wrong way to start, just be aware of where you start and where you are going.
