Definitions of Appreciative Inquiry as shared on Appreciative Inquiry Commons at appreciativeinquiry.case.edu.  

Appreciative Inquiry is the cooperative search for the best in people, their organizations, and the world around them. It involves systematic discover of what gives a system ‘life’ when it is most effective and capable in economic, ecological, and human terms. AI involves the art and practice of asking questions that strengthen a system’s capacity to heighten positive potential. It mobilizes inquiry through crafting an “unconditional positive question’ often involving hundreds or sometimes thousands of people.”

“[Appreciative Inquiry] deliberately seeks to discover people’s exceptionality – their unique gifts, strengths, and qualities. It actively searches and recognizes people for their specialties – their essential contributions and achievements. And it is based on principles of equality of voice – everyone is asked to speak about their vision of the true, the good, and the possible. Appreciative Inquiry builds momentum and success because it believes in people. It really is an invitation to a positive revolution. Its goal is to discover in all human beings the exceptional and the essential. Its goal is to create organizations that are in full voice!”

“Appreciative Inquiry is a form of organizational study that selectively seeks to highlight what are referred to as “life-giving forces” (LGF’s) of the organization’s existence. These are “ – the unique structure and processes of (an) organization that makes its very existence possible. LGF’s may be ideas, beliefs, or values around which the organizing activity takes place.”

“AI is an exciting way to embrace organizational change. Its assumption is simple: Every organization has something that works right – things that give it life when it is most alive, effective, successful, and connected in healthy ways to its stakeholders and communities. AI begins by identifying what is positive and connecting to it in ways that heighten energy and vision for change.” “…AI recognizes that every organization is an open system that depends on its human capital to bring its vision and purpose to life.” “… The outcome of an AI initiative is a long-term positive change in the organization.” “… AI is important because it works to bring the whole organization together to build upon its positive core. AI encourages people to work together to promote a better understanding of the human system, the heartbeat of the organization.”
