Oral Presentation - Obstacles

To sell your ideas to others, you should first be convinced that your ideas will accomplish the task. Oral presentation requires high degree of creative ability. Recall that humans resist changes though they announce that they welcome it. Humans like familiar methods. Changes requires additional effort which humans in general resist. Some usual quotes one hears:

• We tried before
• It is too radical change
• We have never done that before
• Get back to reality
• We have always done it this way
• I don't like the idea

The speaker need to keep in mind that

• Only 70% of the spoken words is actually received and understood. Complete understanding can come through repetition and redundancy in speech.
• People mostly understand three dimensional objects. Two dimensional projections need to be transmitted with added details.
• Usually people perceive problems from their prospectives.
• Convey ideas so that it is interpreted with the least expenditure of energy.
