New Public Management (NPM) sought to infuse private sector efficiency into public administration. In this context, Public Private Partnerships (PPPs) emerged as a mechanism to combine public accountability with private sector innovation and resource efficiency. PPPs challenge traditional closed and open organizational models.

Closed models, such as Weberian bureaucracy, emphasize hierarchy, rules, and predictability but often become rigid and self-referential. Open models, conversely, adapt to environmental changes, relying on exchanges and flexibility, but can struggle with accountability and coherence. PPPs disrupt this binary by creating hybrid arrangements where the state partners with private actors for service delivery and infrastructure creation.

Through PPPs, efficiency, risk-sharing, and innovation are introduced, countering the stagnation (or entropy) of closed systems. At the same time, structured contracts, performance benchmarks, and government oversight attempt to curb the excessive fluidity of open models. In doing so, PPPs strive for a balance—retaining accountability while enabling flexibility.

However, challenges exist. PPPs may create opacity, shifting accountability between partners and diluting democratic control. The profit motive of private entities sometimes clashes with public welfare goals. If not carefully designed, PPPs can reproduce inefficiencies of both closed rigidity and open unpredictability.

Therefore, while PPPs under NPM challenge organizational entropy, their success depends on governance capacity, contract design, and alignment of public and private interests.
