Valid information is the result of an accurate diagnosis of the organization’s functioning. It must reflect fairly what organization members perceive and feel about their primary concerns and issues. Free and informed choice suggests that members are actively involved in making decisions about the changes that will affect them. It means that they can choose not to participate and that interventions will not be imposed on them. Internal commitment means that organization members accept ownership of the intervention and take responsibility for implementing it. If interventions are to result in meaningful changes, management, staff, and other relevant members must be committed to carrying them out.
