- Whether the presenter is present or not
- The amount of detail/data inside the document
The following colorful diagram makes an attempt to visualize the above. A bit busy, the main message is that things are different in each scenario.
- The key note is the classical "Zen" presentation. Huge fonts, dark background, few words, large images.
- The pitch is similar to the key note, with the difference that it might be shorter, and does contain some more data to answer questions from the much smaller audience.
- The meeting presentation is probably done on a light background, and contains much more facts and details. Over-simplified slides with beautiful pictures do not work in the small conference room with people ready to go through raw material. McKinsey and other consulting firm's presentation often fit in this box.
- The slideshare (or online) presentation is something relatively new. People see it typically in small windows, i.e., fonts should be big, pictures should be nice. The audience of this presentation is highly impatient, clicking rapidly to reach the end, and aboning your presentation if it is not interesting enough. No animations here.
- The email attachment is similar to the key note presentatation with an important difference that it needs to stand on its own, titles need to explain the messages in the charts. Some animation could be used here (sparingly though). Detail is less than the handout.
- The handout contains the full detail, the full text. It should be prepared on a white background (people will often print it) and use no animation (again, does not come out in print). For VC pitch situations, the good handout makes the business plan "brick" obsolete (hardly anyone reads these anyway).
