Institutions often assign technology, workforce, climate or infrastructure, and geopolitical questions to different functions. Compound transition asks when those separations stop being analytically sufficient. It directs attention to dependencies, trade-offs, sequencing, and institutional capacity rather than treating every change as an isolated forecast.
The framework helps examine:
- Which changes are occurring within the same planning and governance horizon.
- Where a decision in one domain creates constraints or options in another.
- Which responsibilities sit inside one institution and which require coordination across institutions or borders.
- What evidence would distinguish a durable structural interaction from a temporary coincidence.
Polycrisis, systemic risk, and cascading risk all describe interactions among complex systems. HSI uses compound transition more narrowly, as a framework for research on how institutions respond. It does not assume that every transition matters equally or that simultaneous change must end in institutional failure.
HSI treats compound transition as a working hypothesis and will revise it as evidence accumulates.
