Block Orientation in the Workflow Definition

Use

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.
