Case study
Case Study

  • TCNJ uses PeopleSoft Portal as a gateway to Intranet resources.

  • This particular implementation focuses on Human Resources and Payroll Employees: 20 Power Users

  • Total Time for Usability Strategy/Planning and GUI Design: 4 weeks





Usability strategy
Usability Strategy

  • Get users involved early and often in the design process, to mitigate the risk of re-designing in the development phase.


Get smart early
Get Smart Early

  • You have the most design freedom in the beginning when you know the least about your users. Getting smart early lets you incorporate good ideas before the site is frozen.


Get feedback often
Get Feedback Often

  • You will need the most feedback when you are gathering requirements. However, you will need to test your assumptions throughout the design process.


Data collection prototyping techniques
Data Collection & Prototyping Techniques

  • Direct Methods

    • Personal Interview

    • Screen Captures

    • Contextual Inquiry

    • Focus Group

    • Task Flow Diagrams/Storyboards

    • Card Sort/Reverse Card Sort

    • User Performance Tests

    • User Group Meeting/Usability Roundtable

    • Task Modeling Assessment


Direct methods evaluation
Direct Methods - Evaluation

  • Personal Interview

    • S: Users know best about tasks they perform

    • W: User may provide inaccurate info or leave out important aspects of their work.

  • Contextual Inquiry

    • S: Can watch what user say and do in a real setting.

    • W: Observer can disrupt the user.

  • Usability Roundtable

    • S: Users bring work into a neutral setting for observation and analysis.

    • W: Lacks behavioral validation


Data collection prototyping techniques1
Data Collection & Prototyping Techniques

  • Indirect Methods

    • Survey

    • Usability Questionnaires

    • Help Desks/Support Lines

    • Bulletin Board/Discussion Forum

    • Web Logs


Indirect methods evaluation
Indirect Methods - Evaluation

  • Survey/Questionnaire

    • S: Help collects demographic data.

    • W: May not represent all users.

  • Support Line

    • S: Can gather data on common problems with existing systems.

    • W: Sampling of calls may not be very systematic.

  • Bulletin Board

    • S: Easy for participant to use.

    • W: Sampling of messages may not be very systematic.


Complimentary data gathering
Complimentary Data Gathering

  • Combine various data methods to provide the needed information on time and budget.

Personal interviews
Personal Interviews

  • We began the design process by interviewing HRMS users to gather initial requirements.

  • We asked groups of HRMS users to print screen shots of the HRMS application and identify the links they used to navigate to key tasks.

  • The interface design team then applied usability best practices to group (or chunk) these tasks together by audience and topic and develop a paper prototype of portal navigation shortcut collections.


Reverse card sort surveys
Reverse Card Sort & Surveys

  • Armed with doughnuts and coffee, we presented the paper prototype to HRMS user groups and applied a reverse card sorting technique to identify gaps in our information architecture.

  • At this meeting, we also performed a survey to determine which intranet resources are used most often.


Usability questionnaire brand design test
Usability Questionnaire & Brand Design Test

  • We used these detailed requirements to build an advanced HTML/CSS prototype which contained all of branding and graphical elements (e.g. use of color and icons) of the portal.

  • HRMS users reviewed the advanced prototype on their own computers and were asked to evaluate labeling conventions and comment on branding.

  • We used this feedback to write our detailed design documents and develop the Portal GUI.


Next steps
Next Steps

  • Perform usability test with 8-10 users

  • Write support documentation for customizing portal navigation

  • Monitor user comments with feedback form and surveys
