Executive Summary OneTravel.com is a travel reservation website. The primary purpose of the website is to provide a single point reservation service to different travel booking, for example flight booking, hotel booking and car rental. Customers can reserved these service individually (Flight Booking, Hotel Booking and Car Booking) and they can also book all 3 of these services together (Vacation Booking). In Cognitive Walkthrough, 4 scenarios were created based on different functions in the website. These are booking cheap vacation booking, high preferences flight booking (time, airline, class, etc.), customer service and group booking. However due to the scope of the study for this class purpose, only vacation booking was inspected. This inspection revealed problems that user might have when completing different task within the site. In the Heuristic Evaluation, Nielsen’s 10 Heuristics, was employed in the inspection. This revealed possible problems, based on expert experience, judging on the visual design. Due the task-oriented nature of the website, the inspection result are combined. Similar problem types that exist across the website are are grouped in the global issues section. The detailed results are section into different screens (Vacation Front Page, Loading Page, Vacation Search Result Page and Checkout) for ease of understanding and separation for different development team. The issues are grouped into the following category: • Missing Functionality and Technical Problems – should be considered when adding new features or improving the website features. • Design Dimensions (Graphic / Semiotic, Navigation, Content, Information Architecture, Operation / Transaction) – should be consider when improving the visual design.

Inspection Methods Used A usability evaluation was conducted on OneTravel.com. The two basic methods were used for the inspection: scenario based inspection and heuristic inspection.

Scenario Based Inspection Based on the goals of the site and the variety of users the website can support; four basic scenarios for four different types of users were selected. The first scenario focused on how to book a cheap flight. The second scenario focused on how flight can be booked by a highly constraint customer, book at a specific time, seat selection, etc. The third scenario focused on how customer with less technological competency can seek help within the site. The forth and the last scenario focused on how to make a group booking. Due to the large scope of the inspection and the need to conduct the user testing in the second part of this class, only Vacation booking scenario are inspected. Vacation Booking Scenario a. User: Bill, Graduate Student, 24 years old b. Biography: Bill is a master student at IUPUI. He is enrolled in the HCI program and is very skilled programmer. Right now he is Flat Broke but wants to go to L.A. Since the transportation in L.A. is really bad he would like to rent a car for the whole period of his stay. He also would like to book a hotel, however, he will be visited by his girl friend so he would like to stay in a 5-star hotel on that day. c. Goals: Find a cheapest round-trip flight from Indianapolis to Los Angeles in December considering the duration of stay as 4 days. Book a cheapest hotel for 3 days. Book another hotel (5 star) for 1 day. Rent a cheapest car for 4 days.

Heuristic Inspection The 10 principles are listed below: 1. Visibility of system status 2. Match between system and the real world 3. User control and freedom 4. Consistency and standards 5. Error prevention 6. Recognition rather than recall


7. 8. 9. 10.

Flexibility and efficiency of use Aesthetic and minimalist design Help users recognize, diagnose and recover from errors Help and documentation

Severity Rating Here a severity rating similar to the Neilson’s severity scale is used, however the focus is put on the consideration of the impact on the users. The following 1 to 4 rating scale can be used to rate the severity of usability problems: 1 = Cosmetic problem: need not be fixed unless extra time is available on project 2 = Minor impact: problem that might cause some impact to the user (fixing this should be given low priority) 3 = Major impact: problems that might cause high impact to the user (important so should be given high priority) 4 = Usability catastrophe: problems that prevent user to complete the task or increase the amount of time greatly (imperative to fix this before product can be released)


Inspection Result Due to the task-oriented nature of the website and high numbers of overlapping findings from the Cognitive Walkthrough and Heuristic Evaluation, this lead to the decision of combining the finding into the current format. Presenting the result in this format allow a better flow of information and eliminate redundancy in the document. Pre-combined findings from the Cognitive Walkthrough are provided in the Appendix section of the document. The following sections, Global Issues, Vacation Front Page, Loading Page and Check out are dedicated sections listing the findings from both inspection methods. Additional rationale of this grouping is explained below.

Grouping Similar problem types that exist across the website were grouped in the global issues section. The recommendation provided in this section provide a guideline to improve an overall usability of the website. The findings were further separate into different screens. This creates a better separation of the findings and creates a flow similar to the task completed in the scenario. List of different screen sectioning are listed below: •

Vacation Front Page – The front page of the vacation link.

Loading Page

Vacation Search Result Page – The result of the vacation search, this includes the first 3 steps of the 4 steps process provided in this page.

Checkout – This is the Review and Book page. The operation of this page is ignored due to impossible access of many functions because it is not possible to complete the transaction (credit card purchase required)

To provide the ease of use, Design Dimension and one additional category, Missing Functionality and Technical Problem, were used to categorize the findings. This additional category was added because of the high amount of findings relating to bugs and missing functionality that directly impact the users in achieving the goal. Categories are explained below: •

Missing Functionality and Technical Problems – problems related to missing functionalities that might be required or beneficial to the users and bugs within the website. Due to many encounter of this type of problems, this category is created to better separate technical problems from the design dimensions

Design Dimensions


o o o o

Graphic / Semiotic – problems related to visual designs. Navigation – problems related to missing or inappropriate links between pages Information Architecture – problems related to the sectioning of the information within a page Operation / Transaction – problems related to availability of the operation and the appropriateness of the flow of task.
