In object-oriented programming, sequential coupling (also known as temporal coupling) is a form of coupling where a class requires its methods to be called in a particular sequence. This may be an anti-pattern, depending on context.
Methods whose name starts with Init, Begin, Start, etc. may indicate the existence of sequential coupling.
Using a car as an analogy, if the user steps on the gas without first starting the engine, the car does not crash, fail, or throw an exception - it simply fails to accelerate.
Sequential coupling can be refactored with the template method pattern to overcome the problems posed by the usage of this anti-pattern.[1]
