State pattern for business workflow process

Any thoughts on the applicability of using the State pattern for
implementing a typical workflow process?

We have a problem domain which states that a document needs to be
routed through various individuals/departments for approval or
modifications. Could the state pattern be used for encapsulating the
various states that the document is routed through? Events on these
states would be the individuals actions (through a UI) as it progresses
between the departments.

Any experiences with such an implementation? Any implementation
examples available or any recommended resources on the web?

Thanks.

State pattern would be very suitable for your application.

pattern can be found at:
