Difference B/W Sequential Workflow and State Machine Workflow

Sequential Workflow:

• A sequential workflow execute sequentially one after another and always progresses forward and never goes back to a previous step.
• It represents a workflow as a procession of steps that execute in order until the last activity completed.
• The control of the workflow is decided by the the workflow itself.

State Machine Workflow:

• A state machine workflow moves from one state to another until the logic concludes the workflow has completed and there is no  particular order in execution of each state.
• The control of the workflow is decided by the user.
