Navigation Pattern

Appendix Numbering

A separate appendix numbering format that distinguishes backup slides from the main story.

Use Case

Board packets, financial models, and technical decks with substantial backup material.

When to Use

Use when appendix slides are likely to be referenced separately from the main narrative.

When to Avoid

Avoid if the deck has only one or two backup slides; a separate numbering system adds ceremony.

Best Practices

1

Start appendix numbering only after a clear appendix divider.

2

Use a simple prefix such as A-1, A-2, A-3.

3

Keep appendix labels consistent with the table of contents.
