A SevenSphere this time, based on Cleveland’s 1982 Continuum of Understanding, maps a progression from raw data to wisdom, aligning with the DIKW (Data, Information, Knowledge, Wisdom) model, which a 2007 study by Rowley in the Journal of Information Science confirms is widely used but often lacks empirical validation beyond theoretical frameworks.
Cleveland’s inclusion of "understanding" as a distinct stage between knowledge and wisdom, supported by Ackoff’s earlier work, challenges the linear hierarchy by suggesting a reflective process, a concept echoed in a 2015 study from the International Journal of Information Management that highlights how experiential learning bridges these stages.
What Cleveland missed however was that Understanding of Data, Information, and Knowledge in turning it into Wisdom is also dependent on that is the actual Truth of the matter. And all of that are the aspects of learning as a process.
