DIKW hierarchy

Abstract: This paper revisits the data-information-knowledge-wisdom (DIKW) hierarchy by examining the articulation of the hierarchy in a number of widely read textbooks, and analysing their statements about the nature of data, information, knowledge, and wisdom. The hierarchy referred to variously as the Knowledge Hierarchy, the Information Hierarchy and the Knowledge Pyramid is one of the fundamental, widely recognized and taken-for-granted models in the information and knowledge literatures. It is often quoted, or used implicitly, in definitions of data, information and knowledge in the information management, information systems and knowledge management literatures, but there has been limited direct discussion of the hierarchy. After revisiting Ackoffs original articulation of the hierarchy, definitions of data, information, knowledge and wisdom as articulated in recent textbooks in information systems and knowledge management are reviewed and assessed, in pursuit of a consensus on definitions and transformation processes. This process brings to the surface the extent of agreement and dissent in relation to these definitions, and provides a basis for a discussion as to whether these articulations present an adequate distinction between data, information, and knowledge. Typically information is defined in terms of data, knowledge in terms of information, and wisdom in terms of knowledge, but there is less consensus in the description of the processes that transform elements lower in the hierarchy into those above them, leading to a lack of definitional clarity. In addition, there is limited reference to wisdom in these texts.

Abstract: An organization uses information strategically in three areas: to make sense of change in its environment; to create new knowledge for innovation; and to make decisions about courses of action. These apparently distinct processes are in fact complementary pieces of a larger canvas, and the information behaviors analyzed in each approach interweave into a richer explanation of information use in organizations. Through sensemaking, people in an organization give meaning to the events and actions of the organization. Through knowledge creation, the insights of individuals are converted into knowledge that can be used to design new products or improve performance. Finally, in decision making, understanding and knowledge are focused on the selection of and commitment to an appropriate course of action. By holistically managing its sensemaking, knowledge building and decision-making processes, the Knowing Organization will have the necessary understanding and knowledge to act wisely and decisively
