1. (15 points) Jones Legal Investigation Services, Inc., is a growing business that performs legal investigations at the request of attorneys.? The company owner, Richard Jones, offers a wide range of investigative services, including audio interviews, video interviews, ground accident scene photos, ground accident scene digital videos, and night vision and electronic surveillance.? Using the company?s own plane, aerial accident scene photos and digital videos are also available.?

There has been so much discussion of this issue that you decided to do a little investigation.? After a few ?casual? conversations around the coffee machine, you?ve learned that a system developed for the Distribution Department several years ago was a major disappointment in the company.? Although the system had the features that the users had requested, the system actually ran ?as slow as molasses in January? according to one disgusted system user.

Everyone on the team has been concerned about why the users and sponsor were so hung up on system processing speed.? Now, you know the source of their anxiety, and you?ve shared what you?ve discovered with your project manager.? In response, your manager has asked you to prepare a short memo that discusses, in simple terms, the techniques your team will use to enhance processing performance in the new system.?

1. (10 points) Earhart Aviation operates a multi-service aviation business, including fuel, aircraft maintenance, charter flights, aircraft rentals, and flight instruction.? The company has a major systems development project underway, with a comprehensive system being developed to permit online entry of all work performed in the maintenance shop, fuel purchases, online scheduling of charter flights, flight instruction, and aircraft rentals, and automated billing for the above activities.

Due to the wide range of personnel who will be interacting with the system (from shop personnel to line personnel to office personnel to flight instructors and students), the design of the user interface is important.? Not only should the user interface be thoroughly tested, there must be sufficient user documentation available to help the users work with the system.

Because of the importance of the user interface to the ultimate success of this system, discuss the user interface testing that you believe should be conducted for this project.
