Lets look at the pros and cons
Framework
+ Consistency
+ Predictability
+ Efficiency
- Rigid and limiting
- Bureaucracy
- Stifles creative learning and imposes barriers
Flexibility
+ Innovation
+ Growth
+ Motivational (for some)
- Too easy to stray into dangerous territory
- Requires rigour and discipline to keep in focus
- Allows solutions in the short term which may not be long term sustainable solutions
I used to think of these as a balancing act, to be used in opposing equal measure (how many times have you heard "You need to be able to balance both"?) but I'm not so sure.
I do think you need both but not as competing forces, instead as collaborative. A win win of the best of both rather than one or the other. You need to take the benefits of the framework to the point of diminishing returns and then build upon it with creativity and flexibility.
This cumulative benefit can give you competitive edge or take you to somewhere that might just surprise you.
