Over a long period of time Sears has slipped from being America's largest retailer to struggling for survival in recent years. What cultural change can you suggest to help company leadership at Sears restore some of the retailer's past glory?

I think Sears need to stop diversifying its product too much and focus on improving internal human resources.

Explanation:

The largest expense that Sears made occurred during their effort to add more female customers to shop at their place.

Sears was known for  its DieHard, Craftsman and Kenmore brands that attract mostly male customers to their stores. They started “The Softer Side of Sears”  which focused on adding more products for female customers.

But, in the process of doing so, Sears neglected their already successful male products department with a lot of employees who sacrifice a lot of their time and effort into making Sears as big as it is.

In order to restore to its former glory, Sears need to stop focusing on new market with a lot of strong competitors and focused on improving skill set of employees in their successful department. They can do this by investing in their education, increasing the budget for their research and development, etc.
