@leonardo Nice article! I agree with your framing the challenge of collaborating through data through growth. In my experience, and I think you hinted at it this somewhat, data dictionaries are about the measurement of progress and therefore can quickly devolve as part of a 'political' exchange between departments.
I think that one trend that may have been under-emphasized in the article was the proliferation of tools, especially cloud-based tools, that further define and reinforce an organization's data silos. I am also glad you mentioned > that hard thing about data dictionaries is keeping them up to date over time.
I could not agree more. The reasons why it is hard to maintain over time are equally interesting: Pace of internal tool changes, leadership priorities, lack of data alignment, mega shifts in the competitive environment, etc. There are a lot of gaps with companies getting the most out of their data that relate to the sequence, volume, and urgency of many operational changes made continually.
