You are listening to two employees from your organization's purchasing depart- ment. They are looking over long lists of items purchased by your organization and arguing about how to consolidate these many small spending amounts into a shorter list of larger amounts, so they can later develop purchasing strategies for the items on the shorter list. "We should put the paint for new employees' offices under Office Supplies," says one. The other employee disagrees, and argues something about "Building Maintenance." What process are these two employees most likely engaged in?
