In the informal meeting, Chris begins by saying that the product development team has been busy trying to synthesize all of Hannah's data.

To “synthesize” (synthesize) means to understand a lot of information, usually from many different places, or sources.

Scientists are good at synthesizing a lot of data, or information, from their experiments.

Chris is saying that Hannah has presented a lot of information and that the team has been trying to understand it all and decide how to use the information to improve the product.

Chris says the team sent out, or circulated, a memo last week that described the team's specific ideas.

He says that based on all the signatures on the routing slip, it looks like most people have already seen it.

A “routing (routing) slip (slip)” is a small piece of paper with the names of, for example, everyone in your department, or in your office at work.

You put that slip onto a piece of paper (you staple it or clip it on), and then you give it to one of the people on the list.

That person looks at it (reads it), and then signs their name on the slip, and then gives it to the next person on the routing slip.

Many companies use routing slips to make sure that everyone has read important magazine articles or other company information.

That way, they don't have to make a lot of copies of the document, because they know that everyone will see the same copy.

It's also a way for the company to check (to make sure) that everyone has looked at the document.

Chris sent his memo with a routing slip, and as people read the memo last week, they signed next to their names on the piece of paper (on the routing slip), so he knows that almost everyone has already read the memo.

Next, Chris says that in a minute, or very shortly, he's going to ask people to help the team brainstorm even more ideas.

The phrase “in a minute” means soon, or in a little while.

If someone calls your name in another room, you might yell, or shout, “In a minute!” to let the person know that you will come to them as soon as you can, even though it may not be exactly one minute.

That's a common expression you may hear.
