Management needs to be aware of the finve layers if you want to develop “data-utilization” culture and system in your organization.
The reason I do not use “five requirements” but rather use” layers” is that you do not necessarily have to realize all the five layers.
If your objective is to have your team be equipped with basic data-utilization skills for as a practical tool for daily business operations, then you may not need the top 2 layers to meet. Those two layeres are just for limited professionals.
More importantly, the bottom layer is quite important while many organizations are not aware of its importance, without which your efforts, such as skill training and/or IT system and application installations etc. will not work at all.
My training programs support the second and third layers from the bottom.
