Name the product: Tuubi portal

Purpose/objectives of the test: find out usability issues in the portal's UI in order to improve the ease of interaction.

Method: Test with real users, with task list and unobtrusive observation.

Number and type of participants: 3 people in total.

Tasks: Test persons are asked to complete series of question and see how fast he/she can accomplish the task without any of help.

Results in main points (usability issues found)

  1. The user is confused by too many search functions around the portal (we counted 3) and they all hide a different purpose which is absolutely not clear.
  2. Workspace search: the search results are very near to the searchbox although the user takes a lot of time before recognizing them as the actual results of his search.
  3. Workspace Search: once you tick the checkbox, the subscribe button is hidden.. under another searchbox.
  4. Sidebar of subscribed workspaces has an not a clear criteria on grouping the items. In addition to this, the groups are not graphically well divided. Maybe add some margin-top to the groups?
  5. Assignments tab: the submit/cancel buttons are very distant from the input textbox. This problems becomes bigger and bigger with wider screens because the buttons are floating to the right margin of the page.
  6. Assignemnt tab: when uploading a file as an assignment the system doesn't provide feedback of the uploading going on or being terminated successfully.
  7. Check Assessed assignments: you can't easily understand where's the grade (a number) especially if you are not Finnish: in many other countries there's different conventions (letters, different scales of numeric marks, etc.). There's nothing that says that number IS your grade. Especially because there's not a scale. Eg. 3/5.
  8. The column of grades in the table that summarizes your assignments has no title! The meaning of that number (grade) is more and more difficult to understand.
  9. The mark is visible just in the summary of submitted assignments and the teacher's comments are visible just if you click on your grade. Grade and comment should be displayed contextually at least after you click on your mark.
  10. Fancy Ajax calls don't take in consideration to handle the "back" button of the browser. Typical scenario:
  • login
  • click on a workspace from sidebar
  • now select a tab
  • now another tab
  • let's say I want to go back to the first tab. I click back button.
  • Instead of going to previous tab you find yourself in the homepage of tuubi.

Introduction

Full Product Description

  • Formal product name and release or version
  • Describe what parts of the product were evaluated
  • The user population for which the product is intended
  • Brief description of the environment in which it should be used (this means the context of the use of product/tool, e.g., is it an education product used in primary school, higher education, etc., or maybe research tool used in the field -then what could be field)

Test Objectives

  • State the objectives for the test and any areas of specific interest
    • Functions and components with which the user directly and indirectly interacted
    • Reason for focusing on a product subset

Method

Participants
Three test users: a full-time university student of Arcada (has been using student portal but no Tuubi) ; an exchange student of IT in Metropolia (uses Tuubi just to check announcements and exam dates); another exchange student of IT in Metropolia with very good knowledge of Tuubi and better overally computer skills.
.h4 Key characteristics and capabilities of user group
Users of the Tuubi portal by students' perspective. Fairly good computer skills.

How participants were selected

Users were selected from the target user group as representative of new, basic and experienced user.
Our three test users were well representing the population because of their different experience about the software, but at the same time they belong to the real population of the software tested.

Context of Product Use in the Test

Tasks (criteria of acceptance of each task is shown between brackets).

1. Subscribe to "Usability testing" workspace in Tuubi.
(User has the workspace on his/her General-workpsaces)

2. Go to workspace "Usability testing" and read the description from the frontpage of workspace.
(User finds and can open the description)

3. Find and download file named "Usability_document.doc" and open it on the test computer.
(user is reading the content of the file on the computer)

4. Open assignment "Usability testing 1" and do as you have been told in the assigment (in the assignment test person will be asked to upload a file from the desktop as submitting an assignment)
(user has given his/her answer by submitting a file)

5. Open assignment "Usability testing 2" and do as you have been told in the assigment (in the assignment test person will be asked to give feedback about the assignment as a text)
(user has given his/her answer by submitting text)

6. Read feedback for the assigment
(user sees the grade and comment on his/her assignment)

7. Look up the date for the final assignment from calendar
(tells us the day, month, year and time in which the assignment is due to.)

8. See who else is subscribed to this workspace.
(can see other members of this worspace and tells us what role is himself belonging to)

9. Reply to a message on the discussion board.
(There is a reply from user to Test-message)

Describe the task scenarios for testing

These task represent a selection of most common operations for a student. Principal features of the portal were covered, at least within the perspective of a student who approaches Tuubi as a communication media for university courses.
These tasks were created, chosen, pilot-tested by the organizers of the test.Each partecipant has been introduced to the test environment by a preliminary speech. During this phase we assured to communicate a positive and relaxed mood.

Test Facility Location

Hoas apartments, Leppävaara. Clean study desk with comfortable amount of light and silent surroundings.

Network connectivity: 10Mbit/s ethernet.

Hardware: DELL laptop, 14" screen, Intel Core2duo 2.66 GHz dual core CPU, 2GB RAM. Finnish kbd layout, trackpad mouse. No external mouse available.

Software: Windows XP SP3, Internet Explorer 8. MS Word 2003.

Procedure

The test-user has been instructed with an introductive speech to think aloud for all the duration of his/her contribution to our test.
A printed task list has been provided before starting in a form of per-task numbered list. User has also been invited to read the whole list through and to ask any text comprehension related questions before the test start.
Another printed task list was in hand of the tester, this one complete of the satisfaction criteria.

Test has been handled in two people: a "blabber" and a "scribbler":

The blabber
  • Does the introduction speech
  • Relates to user's question: clearly before test starts and evasively during the test, to keep the observation unobtrusive.
  • Decides and communicates to user and scribbler when the satisfaction criteria were achieved for each task.
The scribbler
  • Positioned behind the test-user, silent and discreet in order to minimize the uncomfortable feeling of being observed
  • Takes note of significant happenings, impressions, behaviors and comments of the user during the test.
  • Takes per-task timings with chronometer.

Participants of this tests were paid back with huge smiles.

Results

Results are mainly qualitative. For someone who is familiar with Tuubi there is no problems completing the tasks easily. That does not mean that Tuubi is good as it is, but that you can learn to master it. One open question is, how steep is the learning curve in Tuubi.

Common usability issues

  • Due to interface back-button doesn't work in Tuubi like user have used to.

Subscribing to workspace

  • User who has little experience on Tuubi may find Tuubi frustrating because it doesn't seem to be intuitive or familiar. Tuubi is somewhat misleading the user in some cases, like when new user tries to find workspace through search-function. Test user tried to find the workspace by using the common search-function (located upper right corner and also in the search-tab) instead going first to Manage Workspaces.
  • Subscribing to workspace is straightforward, but doesn't look that from unexperienced user's point of view. When you try to search for a workspace the search-function does not work when you hit enter. Instead user needs to click the search-button.
  • Search results are shown right below the search-field and there might be several other workspaces. Test showed that it is not easy to locate the search-result. Also the subscribe-button is placed down on the page which means that it is not shown to user unless he/she knows the location and scrolls down.
  • Also test user had problems locating the newly subscribed workspace on her menu of workspaces.

Assingments

  • Test user commented the placement of the buttons on the assignments. When returning assignment the buttons are located bottom of the page in the right corner. Therefore it is hard to spot. User didn't feel sure if her answer had been uploaded succesfully.
  • When uploading files user has no feedback about the upload-process. A loading bar would help.
  • Second test user commented that the grade is easy to miss when you read the feedback. It is not shown on the same page as the verbal feedback.

Positive sides

  • The calendar is easy to use. Users found easy to browse dates or look assignments in listed view.
  • Discussion board is simple and intuitive to use.

Reliability and Validity

Reliability
The tests can be seen as quite realiable. Pilot testing was done with user who has no prior experience about Tuubi but has been using similar software and the first genuine test with unexperienced Tuubi-user showed similar results as in pilot testing. Most of the problems encountered with piot testing were due to incompatible browsers (IE and Firefox running on Metropolias computers). In the final tests up to date-version of IE was used. Also

Validity
Test users were familiar with IE and Windows. Other had been using Tuubi for few months mostly to read announcements and the other had broader and longer experience about Tuubi knowing most of the functions of Tuubi. Finding user who's know-how of Tuubi would have been somewhere between these two would have perhaps provided more information about the learning curve and which are the biggest pain points in Tuubi.
