BOVS

Chirality

BOVS Diagrams are chiral, that is, they can’t be mirrored or flipped – there is a correct way around.

Optional Features such as Annotation and Charts allow BOVS Diagrams to include specific information about ownership and control interests.

If ownership or control information is shown, it must consistently appear on the correct side of the Arrows/Nodes it relates to (see below).

Vertical Diagrams

Vertical BOVS Diagram demonstrating Chirality

In vertical diagrams, irrespective of writing direction:

  • Control information appears on the right side of the Arrows/Nodes.
  • Ownership information appears on the left side of the Arrows/Nodes.

You can remember this with the mnemonic: “control has the rights, ownership has what’s left”.

Horizontal Diagrams

Horizontal BOVS Diagram demonstrating Chirality

In horizontal diagrams, irrespective of writing direction:

  • Control information appears above the Arrows/Nodes.
  • Ownership information appears below the Arrows/Nodes.

You can remember this with the mnemonic: “control oversees, ownership underlies”.
