Integrity is the characteristic of acting in accordance with values even when there are compelling reasons not to do so based on expediency, for example, or potential for gain.
Integrity is strongly connected with trust, in that the individual or organization can be trusted to act solely or primarily based on a particular set of values or principles and cannot be corrupted. Integrity is often recognized as a central value for organizations.
Transparency and accountability are often seen as hallmarks of integrity, in that if an individual or organization is acting from core principles they have nothing to hide.
