Words of advice

1. Identify a single overriding communication objective (SOCO) adapted to your


2. Develop a storyboard: Start with the conclusion slide matched to the objectives, derive a recommendation slide on its basis and then prepare results, methods and introduction.

3. Prepare visual aids with large fonts without “serifs”, good contrast and no more then seven lines per slide.

4. Present digital information in tables and display analogical information on graphs. Add only the maps, pictures and graphics that serve the SOCO.

5. Write a script with full sentences that take slide bullet points as starting point. Push excessive information to the script and the Q&A session.

6. List potential questions and prepare answers.

7. Rehearse over and over again with feedback from a public, and check timing.
