Author: Michelle McCausland
This page contains the notes taken from the UX training course “UX Foundation Online” provided by UXTraining.com
Types of Research
Research can be categorized in 2 ways:
1. Qualitative
- Unstructured
- e.g. usability testing
- not measurable
- provides deep insights
- is classed as a “soft science”
2. Quantitative
- structured
- measurable
- numerical
- produces graphs and data
- is classed as a “hard science”
Remember this: I am not the target audience!
User research is critically important, assumptions are dangerous.
Usability Testing
- The goal of usability testing is to observe what people do / how they interact with the software
- Camtasia / Silverback are pro software tools for screen capture
- It is important to be able to record on screen actions as well as facial expressions.
Benefits of Usability Testing:
- Is the best method to gather requirements
- It presents the product from a user's perspective
- It challenges and validates assumptions
- It produces behavioral data - what people do
Goals behaviors context are important when considering usability.
What you should learn from usability testing:
- What users are trying to do (goals)
- What user do (behavior)
- How the product helps the user to achieve their goals (context)
- Identify pain points
- Identify how the product compares to competitors
Each usability test should have a clearly defined set of test objectives.
Define clear goals.
Be specific - don't try to cover everything.
Create a usability test script:
- Practice/run through prior to test
- Is a useful memory aid to keep you on track
- Specifies the task to be completed
- Specifies questions to be asked
- Start with natural tasks then move onto pre-defined tasks
- Ask lots of what/why questions
Important to state the following to set the tester's mind at ease:
- There are no right or wrong answers
- We are not testing you, we are testing the software
- Don't be afraid to speak your mind
- Think out loud, describe what you are doing
What you need to perform a usability test:
- Tester
- moderator
- note taker
- laptop with mirrored display
- screen capture software (would webex work?)
Tips for moderating:
- Ask the right type of questions
- Rehearse
- Know the product
- Never tell the tester what to do
- Never take the mouse
Avoid
- Direct Yes/No questions
- Avoid leading questions
- Avoid future focused hypothetical questions
- No design questions
Try Instead
- What & Why questions
- What are you looking for/at
- What info do you need to continue and why
- Specific questions about the past
- task questions
Q - What should I test? Existing Product
- The current version
- A prototype of the new design/ designs
- Competitors
New Product
- Competitors
- Prototype
Q - When to test?
- Test early and test often!
- Why throwaway prototypes exist
Online Surveys
Online Surveys
- Easiest way to gather user requirements
- Both quantitative and qualitative
- Powerful and unambiguous
- Cheap/free
- E.g. Survey Monkey
Types of questions on surveys:
1. Structured - provide structured answers - quantitative 2. Unstructured - provide unstructured data - qualitative
3 Golden Questions to ask:
1. Why did you visit out website today? 2. Were you able to complete you task today? 3. What you you change about our site?
Guidelines:
- Never ask more than 10 questions on a survey
- Keep question on 1 page
- Only ask genuinely useful questions
Customer Interviews
“The Mom Test” - Book re. customer interviews
Objectives of customer interviews:
- Understanding customer problems
- Understanding customer goals
- Understand context of use
What doesn't work during an interview:
- Asking for product feedback
- Asking for detailed page design feedback
- Asking about the future
- Avoid talking a lot
- We only want to identify the goals and the problems we are trying to solve
Interview Flow (like a funnel):
\ Intro /
\ General /
\ Specific /
More specifics:
1. Introduction 2. Easy questions 3. Specific recent examples 4. Dissect examples 5. Pain points 6. recap
Interview Guidelines:
- Don't be a robot!
- Don't be afraid to deviate from the script so
- Always record interviews
Stakeholder Interviews
Consider the business perspective - feasibility, viability, desirability
Who to talk to - anyone who has a stake in the product, anyone who provides requirements
Stakeholder interview guidelines:
- To understand the business
- To understand the goals
- To identify competitors
- To get buy in - build relationships - opinions matter
