The the large majority of the senior leadership in the CSSC is "I" driven. The group only cares about their individual groups and not about the collective Accounting Ops support of the company. In addition, many of them don't listen to the business (the branches). The majority of the CSSC doesn't realize they are a support function. They struggle with listening to the branches and customers, and instead think they know the answers and it should follow their way. Great support starts with listening to the market and the customers.
The CSSC was built very fast 4 years ago and many individual contributors were hired without the right skill-set for what is needed now and in the future. Managing them is very tough because they haven't been trained before in their role (AP, AR, Customer Service, etc.) However, what is the most difficult is many don't want to learn and then be held accountable to what was taught. Instead, they rather "get by" and complain to senior levels and HR without working with their direct leaders to improve. This only causes more struggles for department and company progress.
