Every test begins with a clear purpose. Objectives should be specific, measurable, and user-centered. For example:
โ Assess whether users can log in and retrieve saved work within three tries.
โ Determine if students can find and activate help tools in under one minute.
Well-defined objectives form the backbone of an effective test plan.
Detailed Explanation
In any usability testing, starting with clear objectives is crucial. Objectives help define what you want to achieve with the test. They should be specific, meaning they focus on a particular aspect of the user's interaction. Measurable objectives are quantifiable; they allow you to determine if the goal was met. For instance, you might want to check if users can log in successfully within three attempts or if they can find a specific help tool in less than one minute. Such focused objectives guide the testing process.
Examples & Analogies
Imagine preparing for a sports championship. A team would set specific goals, like scoring at least three goals in a match or having at least 70% possession of the ball. These measurable objectives help the team focus on what they need to work on during practice. In usability testing, having clear objectives ensures the design team knows what success looks like.

Choose from several methods depending on your objectives:
1. Think-Aloud Usability Testing
Users speak their thoughts as they navigate your prototype aloud. This gives insight into user reasoning, confusion, and emotions in real time.
2. Moderated Lab Testing
You guide users through tasks in a controlled environment, balancing observation with minimal assistance.
3. Remote Usability Testing
Participants test independently from home while you observe via video or screen-sharing.
4. A/B Testing
Compare two design versions (A and B), measuring task success rates or user preference differences.
5. Guerrilla Testing
Quick, impromptu testing (e.g., asking a friend) to get fast, informal feedback without formal structure.
Detailed Explanation
Different testing methods can yield various insights based on your objectives. For instance, in Think-Aloud Usability Testing, participants share their thoughts as they interact with the prototype, which can highlight their reasoning and any confusion. Moderated Lab Testing involves guiding users in a controlled setting, offering real-time observations. Remote Usability Testing allows participants to conduct tests independently, which is crucial for understanding real-life interactions. A/B Testing compares two versions of a design to find out which one performs better. Guerrilla Testing is an informal approach to quickly gather feedback from random users. Each method offers unique advantages depending on your specific goals.
Examples & Analogies
It's like choosing a study method for an exam. Some students might prefer group study sessions (Moderated Lab Testing) where they can ask questions, while others might benefit from flashcards at home (Remote Usability Testing). A teacher might even give two versions of a quiz (A/B Testing) to see which one is clearer. Choosing the right method, based on what's being tested, can lead to more effective results.

Establish quantitative and qualitative metrics:
โ Quantitative:
โ Task completed: Yes/No
โ Time taken
โ Number of errors
โ Clicks or steps used
โ Qualitative:
โ Participant satisfaction (Likert scale 1โ5)
โ Open-ended feedback: โWhat did you like or dislike?โ
โ Emotional cues: Observations of frustration or confidence.
Detailed Explanation
To evaluate the success of usability testing, both quantitative and qualitative metrics should be defined. Quantitative metrics are those that can be measured numerically, such as whether a task was completed, the time taken, the number of errors, and the number of clicks or steps. Qualitative metrics gather subjective user experiences, like satisfaction ratings on a scale or open-ended feedback that provides deeper insights into user perceptions. Observing emotional cues, such as frustration or confidence, also helps paint a fuller picture of the user experience.
Examples & Analogies
Consider a restaurant looking to assess its performance. It might track the number of diners served (quantitative) alongside gathering feedback on food quality or service (qualitative). Both data types offer a complete understanding of success, helping the restaurant improve its offerings.
