Local Maximum
01 Definition
Local Maximum meaning: A high point reached by small tweaks that still falls short of a much better design.
A local maximum is a good result you reach by making incremental changes, where every small tweak makes things worse, yet a very different approach could perform far better. In conversion work, endless minor A/B tests can trap a page at a local maximum. Escaping it usually requires bolder redesigns tested against the current best.

Why it matters
How Local Maximum fits the work
The idea warns that steady small wins can stall progress, since a page can feel optimized while a fundamentally different version would do much better.
In context
Years of button and headline tweaks left the page at a local maximum until a full redesign, tested against it, converted noticeably better.
Practical note
Small tests refine within one design but rarely reveal a better design. Periodically test a bold, different concept against your current best to check whether you are stuck at a local maximum.
