Block Orientation in the Workflow Definition
A technical lock is the elementary structural element of a workflow definition.
A block always contains a consistent arrangement of steps and operators. A block has one start and one end.
When you define a workflow, you always nest blocks in each other or define blocks after each other. A block can never cover an existing block border.
When you create a new step or change an undefined step, a complete block is always generated. Functions such as delete, cut, or paste always affect the whole block too.
When you create a condition step, a new block is generated.
In addition to the actual step with the condition check, this block also contains the two results of the condition check in the form of outcomes with an undefined step in each of the two possible branches.
