What Drives Performance? (Culture or Process)
The short answer is culture. Regardless of any process that the late Spartans had within their civilization, their culture demanded grit and tenacity. From that core value that that particular state operated on, their process of building fierce warriors and their resulting performance on the battle field dismantled threats more effectively in comparison to their neighboring states.
Process should be snapped onto culture versus being stuck onto it. Hence, there must be a mechanism that supports extensibility over polarity.
In conclusion, the culture must first be assembled for the process before it can be expected to adapt to it.
