In some cases, and for some, "It's my way or the highway," which means if you don't like it, leave.
I am not a big fan of this management style as I believe it leaves a lot of good ideas and substantial experience out of the equation. Even when it's difficult, I'm a big fan of inclusive, strategic processes of development. I find that exclusive processes never seem as successful, efficient, or positive as inclusive, strategic process.
Yet, if you want to change those tight, exclusive processes, it will take a lot of collaborative work by you and your colleagues. It takes a lot of advocacy to make change, and you have to be fully committed to that change in order to devote the kind of time and effort needed.
Almost every time I forget about the exclusivity and narrow paths of some areas of the profession and reach out, I get pushed back as if I'm in a windstorm--a sharp reminder that in those areas of think/work, there is no room for me or my ideas unless I follow the strict path set.
I tend to be a more creative individual, not one who chooses narrow paths--I like the expanse or ever changing, flexible, responsive paths the world offers.
So what to do in the narrow sphere?
The best direction I can see is to learn the strict path, meet the parameters, and use my creativity and big think in other areas. To try to engage in what seems like too-tight paths I fear will be suffocating to my nature, but I can follow the strict guidelines and build out from there on my own. That's the best I can see. If you have another idea, let me know.
