Check out this great review of the field of vertical leadership development, specifically the impact of Collaborative Developmental Action Inquiry (CDAI) by William R. (Bill) Torbert. A brief taste is shown below. Access the complete article in Integral Leadership Review here.
As shown in this review, fifty years of research on real-world practice, guided by the Collaborative Developmental Action Inquiry (CDAI) paradigm of social science and social action, have documented more powerful impacts than any other research and practice approach on leaders’ and organizations’ transformation (Fisher & Torbert, 1995; Taylor, 2017; Torbert, 1976, 1987, 1991; Torbert & Associates, 2004). CDAI is a rich combination of quantitative, qualitative, and action research in field settings where the researchers are also lead-participants studying themselves and their influence on the setting under study as it attempts to transform. In this early stage in the development of the CDAI paradigm, it is quantitatively anchored by the two psychometric instruments currently defensible for measuring and debriefing leaders’ developmental action-logics – the Mature Adult Profile (MAP) (Cook-Greuter, 1999, 2011) and the Global Leadership Profile (GLP) (Herdman-Barker & Torbert, 2012; Torbert, 2013, 2017).
This briefest possible summary of CDAI introduces the key terms “action inquiry practice” and “developmental theory of persons, organizations, and science,” as well as a brief history of the MAP and GLP psychometrics. Next, you will encounter a highly condensed, skeletal set of headlines to action inquiry studies and interventions in the realm of leadership and organizational development. The most practically and statistically significant studies are telegraphically presented, and are also referenced to refereed scholarly journals, PhD dissertations, and research volumes, so that you can dig deeper at will. See also McCauley et al. (2006) for an earlier peer review of the role of action inquiry in the field of developmental theory, research, and leadership.”
