Top Management Team (TMT) Replacement

The mediator construct at the center of an active vault thread on whether a change of executive actor "triggers" organizational restructuring. TMT replacement — turnover among the CEO's direct-report executive team, not just the CEO seat itself — is the specific broader leadership-change event Wangrow, Schepker & Barker (2022) find carries part of the effect of CEO succession through to strategic change: it mediates the relationship for performance-driven and outsider-hire successions, but not for involuntary CEO turnover, which affects strategic change directly. Upper echelons theory and resource dependence theory are the paper's stated theoretical grounding for why TMT composition specifically, not just top-seat occupancy, should matter. The vault first met this construct 2026-07-09, via abstract-level access to the same paper; first_seen is backdated to that date rather than today's re-confirmation, since it is recoverable from the existing claim-note.
