Corporate Longevity: What is the Secret?

Not my area of expertise, however, writing an article about Western and Southern (W&S) as one of several local corporate headquarters in Cincinnati peaked my curiosity. I welcome any insights.

An opportunity arose to relocate to the Queen City from the Big Apple 14 years ago. As an airborne helicopter reporter back then, my pilot would point out the buildings downtown to help me identify landmarks so I could become familiar with the surrounding roadways.

Kroger, Procter and Gamble (P&G), PNC Bank...I was amazed at the number of corporate headquarters located in Cincinnati. Was there a secret formula these companies adapted throughout the years to successfully stand the test of time?

Having had the opportunity to meet several executives in different sectors at W&S over the years, I will use them as an example. A common thread articulated by administrators in various aspects of the group left an impression. Essentially they described a corporate philosophy of investing in the community, (robust arts scene, world-class medicine, higher education) to build the long-term sustainability of its residents. Contributing to the city's economy sends a message to its inhabitants; this organization expects to be here in the next 50 or 100+ years.

Shaped by its CEO and executive leadership the culture of W&S as expressed to me produced a sense of appreciation and value by their employees. Staff members feel acknowledged as vital investments and contributors towards the success and prolonged existence of the financial group. These convictions were based on the actions and behavior of the organization towards their most significant asset. Their employees.

Connecting the dots between the importance of staff and their influence on the growth and success of a business should be clear, right? But is it?

Does a mission statement accurately reflect a company's culture?

How does a large organization identify, and adequately establish the ethos responsible for employees who faithfully remain for 30+ years to support the longevity of the institution? 

I welcome any insights.
