Notional — non-exhaustive. Deck types and density levels will vary by context, audience, and organisation.

WHY IT MATTERS

Professionals are often expected to convey complex information clearly and persuasively; yet, cluttered slides overwhelm and disengage audiences, while sparse slides can leave readers confused.

As a top performer, you are expected to demonstrate communication skill maturity, by understanding the intent of a communication and tailoring content and format accordingly.

Managing text density enhances clarity, build credibility, and effectively influence decision making, leading to better outcomes.

WHAT TO DO

Balance the amount of text to ensure clarity and engagement.

Consider the purpose and type of document you are creating.

The more the reader needs to consume the deck autonomously and refer to it for action (without a voiceover), the more written explanations are needed.

Always write concisely; high text density is sometimes needed but does not mean verbosity.
