When you need a deck and when it is dead weight

A deck is a tool, not a reporting genre

Half the presentations inside companies exist because "you show up to a meeting with slides". Three hours of building, eight minutes of showing, and the decision gets made in email a week later. AI slots neatly into that pattern and speeds up the production of something nobody needed: twenty minutes instead of three hours, and the deck still changes nothing.

Signs you actually need a deck

The decision happens in the room. Someone present will say yes or no during the meeting.
The material is not linear. You need a diagram, a comparison, a trend — things that fall apart in an email.
More than five people. A shared screen synchronises attention; a document does not.
You are steering the conversation. Slides hold the order of your argument when people interrupt.

When skipping the deck is cheaper

A status update for two people — ten lines of text or a table.
Approving the wording of a document — send the document with comments.
Numbers the reader will want to recalculate — a spreadsheet, not a picture of one.
A question that needs an answer today — a message, not a meeting next week.

The one-minute test

1. What decision has to be made? ____________
2. Who makes it? ____________
3. What will they do right after the meeting? ____________
4. Could they decide from a 15-line email?
   YES -> write the email
   NO  -> name exactly what the email cannot carry.
          That missing thing is the content of your deck.

Question four kills more than half of all deck requests. If an email is enough, a deck is a polite way of postponing the decision.

Insight. A deck rarely persuades on its own. What it does is lower the risk for the person saying yes: it hands them the sentences they will later use to justify that decision to their own boss.

Common mistake. Building a presentation in order to think about a topic. Slides are a poor thinking tool: the format forces you to chop an idea into bullets before it has formed. Think in prose, build slides afterwards.

Pro tip. Before opening the editor, write the email you will send after the meeting: outcome, decision, next step. If the email works, you have the skeleton of the deck. If it does not, you do not yet know what the presentation is about.

Cheat sheet

A deck earns its place when the decision happens in the room.
A 15-line email is the first option, not the fallback.
AI speed multiplies the number of pointless decks.
No post-meeting email means no deck either.
