In Retail, the IT approach needs to focused on the Store! An example from Retail/Grocery:
Large organizations can lose sight of the needs of the individual store as they focus on the whole enterprise. If not careful, 'Standards' can lead to inferior solutions when the priority is on what's best for corporate or the data center. A general solution can lead to a complacent approach to the needs of a store. IT Orgs may lack the leadership to inspire the staff to work with the right sense of urgency and focus on the needs of the store. To prevent this, you need to build a culture that focuses on how the retail business makes money: Customers buying products!
Understand the variance of impact each application or service may have on the business. Understand the critical business cycles, understand key usage times, etc.
When you find you are working on a legacy app or system that has no value to the business, time to start asking questions and minimize resources around that service or retire it. When you find that you are asking the 'store' to absorb additional cost or complexity because it simplifies the enterprise supportability, time to revisit your decision making logic!
