The figure depicted the development of perfection of creations (products and processes):
(1) reliability-functionality, (redundancy-overdimensioning),
(2) economy-optimality, (vulnerability),
(3) robustness-resistancy, (undesirable compromises),
(4) lean-simplicity, (missing properties),
(5) orderliness-utility, (the laws of evolution)
(6) success-effectiveness, (best result with the least effort).
