A study by Paquet, Gaétan, and Bergeron (2000) is instructive when considering the form of CB that might be of most use in the current health care environment. Matching 19 cases that used traditional CB with 19 cases that used IBB, they compared CBAs to determine whether the method used would differentiate numbers and types of negotiated changes. Because IBB is built on cultivating understanding between the two parties and open discussion of interests, IBB was expected to yield more changes to the CBA, more mutual gains, and more innovative changes than traditional CB; but each method was expected to yield similar numbers of union gains.
