It's fairly simple. Sticking a couple of resources in the corner to crunch numbers does not change the process of drafting players or ultimately winning games. The task at hand is to change the culture at One Bills Drive to a data driven decisioning making organization. For that you need a solution implementation resource who specializes in change management, not number crunchers. More important than the complexity of the data is how you utilize it.
Like most organizations the Bills use traditional decision making methods, "I think.....". Organizations like this utilize data to back up their "I think" decisions rather than using the data to lead them to the course of action they should take. The culture at One Bills Drive is the problem. People need to be accountable and their processes measurable. Two guys in the corner analyzing data and sharing it in a weekly meeting will not help anything. An entire organization (owners, coaches, players, staff, etc.) measuring their processes and using data to drive their decision making will.
