Incrementalism

Incrementalism is a method of working by adding to a project using many small incremental changes instead of a few (extensively planned) large jumps. Logical incrementalism implies that the steps in the process are sensible. Logical incrementalism focuses on "the Power-Behavioral Approach to planning rather than to the Formal Systems Planning Approach". In public policy, incrementalism is the method of change by which many small policy changes are enacted over time in order to create a larger broad based policy change. Political scientist Charles E. Lindblom developed this theoretical policy of rationality in the 1950s as a middle way between the rational actor model and bounded rationality, as both long term, goal-driven policy rationality and satisficing were not seen as adequate.

In politics, the term "incrementalism" is also used as a synonym for Gradualism.
