Storyboard
In this part of the story, Phyllis needs to plan a new trip.  In order to plan her new trip, she logs in and can drag and drop new clients into a calendar with preconfigured dates.  She clicks the Auto button so that her trip is automatically planned for her.

Visibility 
Visibility of this storyboard is very high.  It uses symbolism from Google calendar, and has a lot of the same features that people are used to seeing.  Programs such as Outlook and Google calendar all work this way where you can input new events and drag the event to the length you want the event to go for.

Learnability 
This interface is very learnable, because even after using the Auto function, the interface is still very modifiable.  Also, once you click the map, you can see another representation of the information entered in by the user.

Efficiency 
The efficiency of this interface is not as efficient as it could be.  Often it could be easier to enter in events without having to drag and drop and enter in events manually.

Errors 
The only error that Errors can result from this interface is the user pressing the button accidentally. However, the "save file" dialog box will allow the user to cancel their action.

if the user does not know how to enter in data.  Clients can be added and removed, so if a faulty client is entered, it can also be removed.  However, because anyone can change this interface, it is very possible that clients that don't actually exist will appear in the client list.

Storyboard
Mary is in charge of approving Phyllis's trip.  In order to do so, she has a visual queue where she can go from one person to the next and figure out who needs to be approved and who doesn't need to be approved.

Visibility 
The approval interface is very visible, because key information appears before Mary.  The important information she needs to be able to see is how much budget she has left over to use and who's trip she is approving.  By having the person's total travel dollar amount and to be able to check that value against her total available budget, visibility allows her to be able to make the accept or deny decision very quickly.

Learnability 
The interface is very visible, because the arrows clearly show that by clicking on the arrows you can click to the next person.  Arrows are symbols used in many other applications, including in web browsers, so the interface should be very easy for Mary or anyone to learn how to use.

Efficiency 
The interface is very efficient if the user's only purpose is to approve or deny people based on a queue.  The interface can become very cumbersome for an employee base that is too large.

Errors 
Errors can result if the user does not know how to enter in data.  Clients can be added and removed, so if a faulty client is entered, it can also be removed.  However, because anyone can change this interface, it is very possible that clients that don't actually exist will appear in the client list.
