ENTITIES - Here are the contents of the three entities used.
RELATIONSHIPS - Here are the relationships between the related entities.

Using BOARD, they can quickly collaborate to answer key strategic questions on what to do next. Thank you to Coulton Carrol for sharing this design pattern with me.
