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.
[[entity-upper-echelons-theory|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.
