CORE DEFINITION

Four-actions framework: Eliminate (factors that the industry takes for granted but are no longer valuable), Reduce (factors that are over-served), Raise (factors that are under-served), Create (factors that the industry has never offered).

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Differentiation design. Do not try to be better than competitors on all dimensions (that would be too costly). You must deliberately do "worse" or even not do some dimensions to free up resources to excel on key dimensions.

The Blue Ocean Strategy's four-actions framework (ERRC Grid) uses four actions - Eliminate, Reduce, Raise, Create - to reconstruct the value curve. The core mechanism is **active trade-offs**: it is impossible to be superior to competitors on all dimensions (too costly), so you must deliberately do "worse" or even not do some dimensions to free up resources to excel on key dimensions, achieving both "differentiation" and "low cost".

MINIMUM ACTION

In progress 0/5

Practice this model in one real situation:

List the current competitive factors in the industry and fill them into the grid
Eliminate: remove factors that the industry takes for granted but are no longer valuable
Reduce: reduce dimensions that are over-served
Raise: raise dimensions that are under-served
Create: create new factors that the industry has never offered.
