Complexity is not a destiny.
Foundation
PREA is the only fully operationalized pre architecture worldwide. It addresses a fundamental problem of conventional systems: complexity is managed at the surface while the structural foundation is missing.
Diagnosis
In conventional systems and in classical top management consulting, workflows are shifted, roles are rearranged or processes are adjusted – comparable to changing buildings, paths or visitors on a square without examining the ground beneath.
Effect
PREA operates at the level where stability, traceability and resilience emerge. It establishes the structural conditions for reliable workflows and consistent decisions.
Provision
Lehmann Systems opens access to the complete architecture as well as the associated materials and formats.
Contact
Organisations seeking to implement or license the architecture can engage Lehmann Systems as
the standard‑setting authority.
