Shawn wants the company's product to have more of these nice things that customers are looking for.

Shawn also says that the company needs to revamp its marketing efforts.

“To revamp (revamp) something” means to improve something, or make something better.

Revamping the marketing efforts means changing the way that the company does its marketing.

Revamping your room might mean painting the walls and buying new furniture - new chairs, a new desk, and so forth.

At the end of the meeting, Shawn asks Hannah to “take over” and talk about what she learned from the focus groups.

“To take over” means to take control of something, to be in charge.

In this case, Hannah is going to be in control, or be in charge, of the next section of the meeting.

That's all the new vocabulary in the informal meeting.

Let's listen to Shawn again, this time when he's speaking more quickly.

Shawn: As I said a moment ago, our market share has taken a nosedive in the last year.

Why? We think it's a combination of three things: (one) there's a lot more competition now than there was a year ago, (two) our product isn't meeting the needs of the market, and (three) our advertising is speaking to the wrong customers.

These are some pretty serious but not insurmountable problems, so let's take a look at the solutions we've come up with.

First, we're facing twice as many competitors as we were a year ago, so we need to make sure that customers know that Vision Corp.is the best in the business.

Second, we need to make sure that our product has all the bells and whistles that our customers have come to expect.

And third, we have to revamp our marketing efforts and make sure that our ads appeal to the right group of customers.

Hannah, can you please take over now and tell us what you learned from the focus groups?

Now you know some of the business vocabulary used to make presentations.

In the next lesson, number five, we're going to continue learning vocabulary for making presentations, but this time we will focus more on the vocabulary for using visuals, the drawings and images that help people understand what they're presenting.
