Usability Testing
Why hello, welcome to another hipster-related article! Today, I’ll be writing about usability testing, or UT for short!
What is Usability Testing (UT)?
Before we get into usability testing, let’s define what usability is. According to ISO, usability is “the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use”.
The definition can be broken down into this illustration below:
With this, usability testing is a qualitative research method to validate and test a software design in regards to completion, errors, task time, and user pleasure. This is done by observing an individual’s experience with a concrete prototype as they walk through the steps of a given task.
Basic Scenario for RaisingStar UT
Now we’ll discuss about the UT that I did for RaisingStar. First, the scenario.
For the scenario, I tested the features that are included “Menjalakan aktifitas”
#1 Client Scenario
- Account Registration
- Child Registration
- Dashboard
- Activities
- Sub Activities
- Doing Activities
Usability Test Result
Because of time and availability constraint, I only managed to conduct usability tests to one persons. Here are their profile and also the results from their usability tests below:
#1 First Respondent
- Age: 20
- Gender: Female
- Occupation: Undergraduate Student
The first respondent has never used a similar app like RasisingStar.
During UT, the first respondent didn’t find any significant hurdles when they were doing the specified tasks. The respondent managed to find and use the features that are available on the application/prototype. What the respondent likes most about is it’s RaisingStar minimalist design and how the colors evoke a sense of calmness.
#2 Second Respondent
- Age: 26
- Gender: Female
- Occupation: Worker
During UT user have difficulty to navigate to activity page, some of navbar cannot be clicked to get back home or other. But to do activities there any significant hurdle.
- Some navbar bar cannot be clicked
System Usability Scale Result
After the usability tests, I also gave them a System Usability Scale (SUS) questionnaire to fill.
The SUS is a reliable tool for measuring usability. It consists of a 10 item questionnaire with five response options for respondents; from Strongly agree to Strongly disagree. The SUS will result in a scale that ranges from 0–100, which can be interpreted as below: —
After calculation, here are the SUS result that we obtained from the two respondents:
- Respondent 1: 83
- Respondent 2: 84
In average, the SUS score obtained is 84.5 .
Based on the scale above, the current design is categorized as ‘Execelent’. For a first iteration, I feel we did a pretty great job in designing the application.
The next step would be to consider and apply the suggestions given by the respondents, but that will be done in a future occasion.
And that’s it for this article! Thanks for reading!
