Problem• With the current drive-thru system, consumers need to speak

through an intercom to place their order. 

• Miscommunication between the customer and the server can cause errors in orders and also confusion, in addition to the fact that people may feel self-conscious when speaking to a box.

• The new drive-thru interface eliminates these problems.  The drive-thru interface also attempts to improve the ordering speed. 

• Present systems require that a server(person in charge) be present to take an order.  Often times, a driver must wait for a server to appear, resulting in inefficiency. 

• With our computer drive-thru interface, drivers can automatically begin ordering food without the need to wait for a server.

Objectives• We recognized the need to improve the process of ordering food at

a drive-thru window of a fast food restaurant. 

• The current drive-thru system has several drawbacks that we want to improve and will allow customers to have direct control over making and changing their orders.

• Our team decided to implement a touch screen interface drive-thru system with the ultimate goal of providing users with a food-ordering interface that is consistent, intuitive and easy to use.

Project Scope• For this project, our team decided to use McDonald’s as the

restaurant because of its recognition and well-known drive-thru service.

• The drive-thru interface is designed to provide customers everything they need to order their food.

• Note that users must still pay and pick up their order at the window.

Who are the users?• The intended users for our drive-thru system are novice and casual

users who are able to drive (age over 18 in Malaysia), and seek quick quality service restaurant.

• Our system is developed to accommodate people with all different levels of knowledge in computerized systems.

• Since McDonald’s is very popular in many different countries, our intended users are spread all over the world.

• Our system can be implemented in any restaurant that offers a drive-thru service.

Tasks?• Ordering

• Canceling Order

• Reduce Quantity of Order

• Special Request

Discussion• The result is as expected as the system is meant to be easy to use and not complicated which

makes the system less challenging.

• In terms of performance, overall every user have passed of 50% of the user performance in terms of time taken to complete each task.

• Every task has been completed 100% with ease and there are even certain users that perform as fast as the expert of the system.

• By far, the hardest task would be task 4 which is the special request as it takes time to key in the special order request.

• The easiest task would be task 2 which is cancelling order as it is quite straight forward and fast.

• Based on the performance score, the usability of our prototype is looking good as users doesn’t really face critical problem.

• From the mean and the standard deviation, almost all of the user finds the system attractive, not confusing, easy, not that annoying, quite helpful and not that challenging.

• We think we should improve the way user inputs the special request as it takes really long time for user to key in so we might insert some defaults for the user to choose.

Conclusion• The design process was incredibly informative and the experience was an excellent

one. We learned a lot, not only technically related, but also in regards to time management and teamwork.

• We learned about Usability and how important it is in the design process, as well as imagining ourselves in the place of the users. Through our project we found that what we necessarily thought was important and needed in an application wasn't exactly what the user wanted and needed.

• This showed us how important prototyping is because a company that dives into a project without actually taking the time to make a prototype may end up with catastrophic sales if there is a certain feature that either is inconvenient to use, doesn't do what it is intended to, or isn't included at all.

• By building the prototype of Touchscreen Drive Thru Interface, we definitely gained a bunch of experience and not only learn more on prototyping but also the way we work as a team.

• Users of our system were also very receptive to the idea of Touch Screen Drive Thru Interface. Implementing this system for real in future would be a great deal for us.
