Understanding workflow execution process exercise

Workflow diagrams

Look with care the next four workflow diagrams and try to imagine the differences between execution process.

Which will be the sequence execution of each workflow ?

Workflow one:

Workflow two:

Workflow three:

Workflow four:

Solution

• Workflow 1 arrives directly to end without any break.
• Workflow 2 arrives to end after "task3" execution or "task1" and "task2".
• Workflow 3 executes node "1" and then goes to end.
• Workflow 4 can arrive to end from any of tree nodes. Always is required human intervention to finish because each branch has a task node.
