International Journal of Appreciative Inquiry
The PILAR model of collaboration contains five perceptions of collaboration held by group members: prospects, involved, liked, agency and respect that occur in idealised collaboration, which presumes voluntary membership, sincere commitment and equal member power. PILAR is used to explain the strengths and weaknesses of two contrasting perspectives on collaboration: qualitative
(Appreciative Inquiry: AI) and quantitative (organisational and industrial psychology: OIP).
