Constancy of purpose plus never-ending operational improvement

There's a critical distinction that most business leaders miss: some things should never change, and other things should never stop changing. Constancy of purpose means keeping your core strategic elements constant — your fundamental positioning, your market promise, your brand identity. Never-ending improvement means continuously enhancing how you execute operationally — your customer experience, your processes, your team skills. Without clarity on which is which, team members will change strategic elements that should remain constant and keep operational aspects static that should be improving. Southwest Airlines is the classic example: they maintain their core low-cost airfare strategy and standardized fleet unchanged, while continuously improving the customer experience within that framework. Confusion between these two principles is one of the most common causes of business stagnation.
