Interaction is characterized by reciprocal actions between individuals affected by a change and the steps they take to move the change process forward. Interaction spurs discussion, sharing, debate, and the comparison of ideas and practices. Regardless of staff members' roles or status within an organization, it is through interaction with each other that they eventually build a vision of the change to be implemented. Interaction fosters -coconstruction, which is why it is important to emphasize the quality, frequency, and diversity of interactions. It also encourages individual and group questioning, awareness building, adjustment, regulation, analysis, evaluation, and observation. Interaction can help staff move forward in adopting change and in updating their professional practices, or in adapting their models of practice (for further explanation, see Lafortune, 2008a,b).
