A system - biological, technological, organizational - can see a higher peak ahead, but to reach it, it must first get worse. It must pass through a dip in performance, stability, or fitness before climbing to a superior design. Evolution avoids these valleys because natural selection punishes anything that loses capability, even temporarily. Many pure researchers/engineers always think in terms of great end result, w/o understanding that their proposed solutions will carry a lot of short term pain and thus likely to be shut down by management (who can't truly understand the better outcomes).
