5 Days to a Data Maturity Model for Data Governance: Day 5
Hopefully yesterday you were able to review and fill in the sample maturity model template I provided you for. If you did, it should all be coming together for you. You likely have 5-7 Maturity Levels that are a tailor fit for your organization, and specifically your data. Remember, we crafted the model around what was already occurring within your data today. Thus, we didn’t really create a model; we actually just applied labels to your existing data tendencies. It is best to do it this way because your data will naturally follow the model going forward. Today we are going to look at the task of making sure your model works by reviewing it against your data. If you make it out of these simple tests, your maturity model is golden.
First things first, get the following out: Your data governance maturity model template (filled in) and the in-scope data for your program. What you are going to do is take a sample of your data and make sure that you can easily find the position of that data on the maturity model. If I were doing this again, I’d randomly pullout about 40 fields and go one-by-one through them. I’d look at the field, check the model, check if their is metadata, etc., and see if it falls into a level.
You need to make sure that all of the data fields fits somewhere on the maturity model… if it is questionable you may not have defined your levels clearly enough. If it falls right between two levels, you may need to define a new level to account for the difference, or incorporate the characteristics into one of your existing levels.
If everything is good to go, the final step is to tag all of your data with its maturity model level. I always work with the data modelers to do this, as the elements need to be tagged within the data model.
