Cheatsheets for UX research! Why?

We answered that question in the first article of our Cheatsheet series and that can be found on this Cheatsheets for UX research! Why?  

In the second article of this series, we shared the Cheatsheet for preparing and conducting user interviews. That is a useful piece of information to keep handy. Read it Cheatsheets for User interviews 

In this cheatsheet, the third of the series, we are taking up the topic of Unmoderated Usability testing.

To build some context, Usability testing is an evaluative user research that enables the key stakeholders and project team to understand how people interact with a product. The usability testing can be performed during the design, development or post the release of the product. In a usability test, during the product usage, participants are required to perform certain tasks using the product and provide their feedback.

Research methods used in usability testing can be remote or in-person. The types are:

  1. User interviews
  2. Unmoderated usability testing 

 

Types of unmoderated usability testing

To demystify the term “unmoderated” and its association with usability testing, it means research participants use the product when no one is watching or interacting with them. 

Two types of of unmoderated usability testing can be conducted:

a) In-person unmoderated usability testing 

The participants use the product at a predetermined physical location. No one watches the participants during the time they use the product. The interaction and any comments made during the product usage may be recorded and probed by the researcher after the usage session is complete. Since this method of usability testing requires the presence of researchers and participants at a fixed location and time (read logistics), this method is less popular compared to remote unmoderated usability testing.

b) Remote unmoderated usability testing

This method is conducted using an Internet (SaaS) based user research platform. In this method, the participants and the researcher need not be at one location and at any specific time. They may be in any part of the world where access to an internet connection is possible. The participants perform the tasks and during product usage, their interactions are recorded and uploaded to a server. Later at a time of their choice, the researchers access the screen recordings of the interactions and interpret the feedback from the participants. This feedback includes verbal think-aloud comments and may include face recording.

Steps to setup an Unmoderated Usability Test

Following preparation is necessary in order to successfully conduct unmoderated remote usability testing.

i) Establish the usability testing goals

ii) Identify profile of participants

iii) Screen and shortlist participants 

iv) Select a User Research platform

v) Prepare Test materials 

vi) Prepare Tasks to be performed and the list of usability metrics

vii) Prepare questions to be asked after the tasks are completed

viii) Do a test run prior to test launch

 

The above steps are detailed out for reference. 

i) Establish the goals of usability testing

To establish the goals, follow these quickies:

  • What do stakeholders want to find out
  • How would the findings be valuable to the business
  • Is the research method suitable for all the goals
  • Do all stakeholders have a shared understanding of the goal statements
  • Which of the goals can be included in the subsequent rounds of usability testing

 

ii) Identify profile of participants

  • Number of profiles / Personas being targeted 
  • Demographics of the target audience e.g. age group, gender, nationality, income
  • Behavioral attributes of relevance e.g. what they do, like, dislike
  • Number of participants in each profile aka Sample size

 

iii) Screen and shortlist participants 

  • Prepare a list of Screener questions to shortlist participants
  • Identify the answers which should qualify / disqualify the candidates from participation
  • Comfort level in think-aloud 
  • Include a question to check the capability in articulation of feedback
  • Gather contact details to distribute the usability test and reach out if necessary
  • Ask for consent of participants to participate and agree to get recorded
  • Ask for consent of participants to agree in storing their personal information, if any
  • Include incentive type / amount and method of payment

 

iv) Select a User Research platform

  • Select a remote usability testing platform based on what you want to collect and what participants would be testing.
  • Does the platform support the research method e.g. Task based test, Card Sorting, Tree Test, 5-second test
  • Does the platform provide participant recruitment
  • Does the platform support testing of test material e.g. LIVE Mobile apps
  • Does the platform support the devices the test must be conducted on e.g. Computer or Mobile device
  • Is the platform Video-centric e.g. usertesting.com, UserZoom, UXArmy, etc.
  • Is the platform Usability Metrics-centric e.g. Maze, Useberry, UsabilityHub, etc.

 

v) Prepare Test materials 

  • Find out and decide what you want the participants to test, options being:
  • Wireframes using tools like Balsamiq, Figma, Sketch
  • Design prototypes using Figma, MarvelApp, Proto.io
  • Mobile websites - Staging or LIVE
  • Mobile apps - Staging or LIVE
  • A non-disclosure agreement to be signed by the participants, if necessary
  • Usability testing Plan must include the availability of Test materials as a dependency 

 

vi) Prepare Tasks to be performed and the list of usability metrics

  • List the tasks the participants would perform. Shape up the tasks based on what users would accomplish by using the product.
  • Keep to 5 or 7 tasks
  • Each task must map to the goals of the study
  • Tasks must be clearly worded and unambiguous
  • Clear success criteria
  • Each task must mention an end state for participant to know that task has been completed
  • Task flow i.e. the sequence in which tasks are to be presented
  • Identify usability metrics for each task
    • Success / Fail
    • Time to complete the task
    • Time to first click / tap
    • Number of clicks/taps
    • Number of swipes
    • Navigation paths e.g. path and number of pages / screens
    • Number of Retries for a task

 

vii) Prepare questions to be asked

  • survey questions can be asked at the end of all tasks and also immediately after performing any task
  • survey questions can be of various types:
    • Open question
    • Single or multiple selection
    • 5-Point / 7-Point Likert scale
    • Dropdown
    • Matrix
    • Ranking
  • Ask questions for recall, task difficulty and also to collect any additional information relevant to providing background information about participants e.g. other similar experiences they have had
  • Some researchers include standard questionnaires like SUS, USERindex, UEQ, etc.

 

viii) Do a test run prior to test launch

  • Also known as Dry-run, experiencing the test yourself helps to refine it.
  • Dry-run with internal and external participants
  • Measure if there is fatigue factor in completing the Test
  • Check if all is working as expected e,g, prototypes are loading properly and are the correct ones
  • Finetune questions and include things which might have got missed
  • If all is good, launch the Test

This is the third of the series of Cheatsheets for User researchers. Throughout the year, we’d continue to develop more cheat sheets and infographics for User researchers and we hope this would come handy in your work.
