Lesson five.

I'm your host, Dr. Jeff McQuillan, coming to you from the Center for Educational Development in beautiful Los Angeles, California.

In the fourth lesson of “Business Meetings,” we learned some vocabulary for giving a presentation at formal and informal business meetings.

In this fifth lesson, we're going to continue talking about how to give presentations, but this time we'll focus on using visuals, the images and pictures that help people understand what's being presented.

First, let's listen to Hannah's presentation at the formal meeting.

Hannah: Thank you, Mr. Edwards.

We conducted eight focus groups, each with 10 to 12 people who currently use the product.

In this pie chart, the yellow-shaded area represents those participants who buy the product from Vision Corporation, and they comprise only 13% of the people we spoke with.

That's consistent with Vision Corporation's market share segment.

We asked the participants what features they wanted when purchasing the product and this table shows their answers in descending order of importance.

As you can see across this row and down this column, Vision Corporation's current product offering includes only one of the top three most desired features.

Finally, we asked the participants to rank the product offered by Vision Corporation against those of the top four competitors, and the results are shown in this bar chart.

Vision Corporation received the best rankings for “affordability,” but suffered in all the other categories.

This line graph shows that these figures have held steady over the four months we've conducted these focus groups.

We believe this means that your company would be justified in raising the price of its product and using the additional revenue to improve the product's features.
