This paper explores the definition and nature of integrity through an analysis of the variation in individuals’ perception and experience of integrity using phenomenography as a research approach. Both the research and the literature show variation in definition and perception of integrity; there is no single, agreed definition. Integrity is both personal and relational, and it requires a dynamic balance between consistently thinking, feeling, and behaving within personal moral boundaries, as well as within legal and moral societal boundaries. Intent and motives are an important part of integrity, and the only way that we can know the motives of others, and they know ours is through effective dialogue. Integrity is a core value, with moral content; it is about what is right and wrong. The research has implications for organisations which count integrity as a value, since it must be defined by them in a way that can be understood and consistently demonstrated at an individual and collective level.
