Developmental coaching is predicated on the possibility of meaningful psychological transformation, yet experienced coaches consistently observe a paradox that existing theory has not adequately resolved: developmental breakthroughs reliably give way to new forms of psychological organisation, suggesting that adaptive structure persists across development instead of disappearing through it. This paper proposes that adaptive persistence is best understood as a recurring cycle, alternating between periods of relatively stable psychological organisation and periods of active developmental change, instead of as a single transition. Drawing on Levinson’s (1978) account of alternating structure-building and structure-changing periods across the adult life course, and on Fischer’s (1980; Fischer & Bidell, 2006) dynamic skill theory, which documents that developmental performance varies and can temporarily decline before reorganising at a more complex level, the paper introduces developmental opening and developmental reorganisation as the two phases through which this cycle proceeds. The model integrates constructivist-developmental psychology, psychodynamic theory, phenomenology, humanistic and existential psychology, contemplative psychology, and coaching philosophy to argue that development transforms the organisation of adaptation; it does not abolish the need for it. The paper interrogates the model’s own assumptions, considers alternative interpretations, and examines implications for coaching philosophy and practice, arguing that coaches should attend to both the moments of developmental opening and the recurring, lifelong process through which clients reorganise their identities, values, and meaning-making.
