TOGAF, a framework for architecture from Open Group, defines the data management principles. We can go into them being complete or not the only principles arguments, or why TOGAF is not your favorite framework; but, that won't be the focus of this discussion.
These principles as listed are:-
I find it very apropos that they mention the first three to be linked. For IT management:-
Now the link for these is kind of obvious, may be the second and third could have been combined, how could one share without making it accessible? But, I digress, into splitting semantic hair…
The obvious conflict comes from application of the "Data security" principle. Which, needless to say, is very important when all the excitement is around security breaches leading to "identity theft crisis", election rigging, fake news, and what not…
But, all the politicians, have known this since the ages bygone… that "securing" information is the most important aspect. And, I did not bring in "politician" into conversation in vain. Politicians who divide and rule, as opposed to leaders. Leaders get the things done. And, the leaders who get the things done economically, while keeping the trust/well being of the people around. Economically, does not mean miserly; that, again is the ruse of "politicians" who would use the latter as a way to mislead and thereby to divide.
So, if you are the decision making leader, and want to be "the architect" of success for your organization, you know that you have a lot of variables in the equation, and what you are attempting at any given time is to optimize a multi-variate equation, maybe even a bit complex than the equations used by rocket scientists in fluid dynamics. Don't let the single point detractors take you away from that. Your followers already know that. And, if you are a follower know all these details to decide who should be your leader(s).
Going back to "data security" it is a very important feature, but don't let it get in the way of equally important triumvirate of data principles that it is "an asset", "shared" and "accessible". It is not the first and foremost principle but there for support because of the other three principles. So, go ahead and architect your team's success, securely!
