The slides from my General Assembly workshop on January 13th, 2013 (https://generalassemb.ly/education/introduction-to-usability-testing-the-diy-approach) ABOUT THIS WORKSHOP Usability testing can quickly uncover areas of an interface that frustrate users and hurt business goals but many teams put it off due to budget, time, or training concerns. This workshops will take you through a do-it-yourself approach to usability testing. We'll cover the basics (benefits, recruiting, and how to plan a test), learn how to facilitate a test to get reliable results, and how to use the testing results to move usability improvements forward. You'll walk away with the tools to hold a complete usability testing right away. TAKEAWAYS Learn why and when to hold usability testing Learn practical tools and methods to overcome time, budget or training concerns that block user testing from happening Shift the conversation from opinions and hunches to proven usability problems that your team can solve together

USABILITY IS A MAJOR BUILDING BLOCK OF A GOOD EXPERIENCE

USABILITY TESTING: WHAT & WHY

1. INTUITIVE (n.) Using what one feels to be true without conscious reasoning

USABILITY TESTING: WHAT & WHY !12

NEEDING INSTRUCTIONS MEANS SOMETHING COULD BE MORE SIMPLE.

USABILITY TESTING: WHAT & WHY !13

2. EASY TO USE Doesn’t make people feel stupid or inferior to the tool they are using. Helps them feel in control.

USABILITY TESTING: WHAT & WHY !33

— DANIEL Lead Developer, Future Workshops

“!

I was completely surprised at how cumbersome the users experience with the app was. Basic tasks were which was so obvious to me were suddenly a huge barrier.

USABILITY TESTING: WHAT & WHY !34

— DANIEL Lead Developer, Future Workshops

“!

... What the usability testing did for me was really prove how much tech people can lose sight of who they are building for. It about going back to basics in some cases.

USABILITY TESTING: WHAT & WHY !35

IN SUMMARY: USABILITY TESTING BENEFITS

1. Highlights where our product isn’t intuitive / easy to use

2. Puts team in the shoes of users

3. Helps sell product improvements to stakeholders/ clients

4. Helps prioritise feature backlog

3 / TURNING DATA INTO ACTIONS

!37

PREPARING A TEST PLAN !38

To run a test, you need

‣ Some representation of your product

‣ Preferably interactive

‣ Doesn’t have to be finished

‣ Or: competitor product!

‣ Idea of what you want to test

PREPARING A TEST PLAN !39

What do we test?

‣ General impressions

‣ Ease of use of critical features

‣ Features we’re not sure about (e.g., is the help clear?)

‣ Response to design, iconography

Tip: start from high-level when testing prototypes, test the details with later builds

You need to cook a new recipe for the company potluck. You found a recipe online and now you need to buy the ingredients and cook it.

You need to remember what to buy. Use the app to make a shopping list you can take to the supermarket.

Print-out of a recipe from the internet

Create a text note and make a bulleted list of ingredients

E-mail a note to a friend using swipe to share

Text note Share a note via e-mail

You really liked the new recipe and you think your friend Jenny will like it too.

Send the recipe to Jenny from within the app.

Jenny’s email: jenny@futureworkshops.com

Don’t show this to the participant!

PREPARING A TEST PLAN !54

Scenario Structure !

‣ Your character

‣ Your motivation

‣ What you need to do

‣ Any details like login information, etc

!

// SCENARIO

PREPARING A TEST PLAN !55

Scenario Tips

‣ Avoid using terminology from the interface (e.g., search, tag, filter)

‣ Scenarios can have steps (e.g., find a recipe and add it to your collection)

‣ Escalate the difficulty as the test progresses

Tip: make the scenario specific enough so someone can relate to it, but not specific enough to exclude people

EXERCISE 2: CREATE A TEST PLAN

Learn to write a non-biased test that covers the features you need tested

20 mins !56

1. Using the Test Plan Worksheet, define 3 key tasks that must be intuitive and easy to use in the application

2. Identify the success paths for each task (what we expect users to do)

3. Write specific tasks, then a general scenario

4. Run through the complete test once

Filled out test plan worksheet, ready to be used in a test with a participant

USABILITY TEST STEPS

RUNNING A USABILITY TEST !59

As a facilitator, your jobs are:

‣ “Tour guide”

‣ “Therapist”

‣ Burst the thought bubbles

http://books.google.co.uk/books?id=9Q3OQVyX_-QC

From: Rocket Surgery Made Easy by Steve Krug

RUNNING A USABILITY TEST !60

‣ Practice staying quiet

‣ Remind the participant to speak out loud

‣ Don’t give anything away

‣ Be reassuring, say thank you

‣ If they get stuck, wait (a little)

Facilitating

RUNNING A USABILITY TEST !61

Facilitator Cheat-SheetIf they forget to think aloud

‣ "What are you thinking right now?"

‣ "What are you finding confusing on this screen?"

‣ "I know it's an unusual thing to do but could I please ask you to keep thinking out loud and talk as you go along? It really helps me understand your experience better."

RUNNING A USABILITY TEST !62

Facilitator Cheat-Sheet

If they get upset

‣ "This is very helpful for us, we are uncovering a lot of problems in the design that will help us make the app better.”

‣ You’re struggling with the same areas that other participants found confusing - you’re totally normal

RUNNING A USABILITY TEST !63

Facilitator Cheat-Sheet

If they have a question

‣ "Please continue in the way that makes sense to you. We will learn a lot from seeing how you proceed with this without any help."

RUNNING A USABILITY TEST !64

Facilitator Cheat-Sheet

The golden go-to

‣ "We expected to uncover problems in the design. You are not doing anything wrong - we knew there would be issues and you are helping us find them."

RUNNING A USABILITY TEST !65

PEOPLE WILL FEEL STUPID. MAKE THEM FEEL AT EASE.

RUNNING A USABILITY TEST !66

Facilitator checklistIntroduce yourself and anyone else present

Thank the participant for coming

Explain why they’re here & what will happen

“We are not testing you”

Introduce thinking aloud

Explain questions, breaks, and ask if they have any questions

Optional: consent forms, recording, interview

RUNNING A USABILITY TEST !67

Ways to record our findings

From easy to complicated

‣ Pair up with a note-taker

‣ DIY recording equipment

‣ Professional recording equipment

‣ Live-stream to a group of stakeholders

RUNNING A USABILITY TEST !68

NOTE-TAKING BRINGS DOWN 2 BARRIERS TO TESTING: TIME & EQUIPMENT

(But I’ll give you some tips on recording later!)

RUNNING A USABILITY TEST !69

Note-taking tips

Only record what’s important

‣ If someone is really happy

‣ If someone is really frustrated

‣ If someone fails a task

‣ Write down short quotations

RUNNING A USABILITY TEST !70

Notes Example • Taps Map on merchant profile but this opens the system

Maps app — confused !• Goes to Search and types “coffee shops” but there are no

results — “why can’t I see what’s around me?”

!• "If I had to think about something around me, I’d start

the merchant profile and expect to see other things around me"

!• The icons aren’t telling me that Cafe Nero is a coffee shop

!!

RUNNING A USABILITY TEST !71

What to bring to the testPrinted scenarios & tasks for participant

Printed scenarios & tasks with success paths for facilitator

Facilitator script

Consent form (if needed)

Pen + paper / recording tools

Test setup checklist

Optional: List of pre-test and debrief questions

Tip: Prepare a printed copy of the scenarios & steps for the participant, they will use it

RUNNING A USABILITY TEST !72

Setting up the testReset the mobile app / site to the default settings

Clear the test area of any open documents, written notes, etc.

Prepare participant forms: scenarios, intro script, consent form

Optional: Verify the recording equipment

Optional: Make sure the brightness on the screen is reduced

EXERCISE 3: USABILITY TEST

1. Gain experience facilitating

2. Collect notes containing usability problems

3. Identify weaknesses in your test plan

40 mins !73

1. Every round, swap one member of your group in exchange for a member from another group

2. The ‘foreign’ member is the participant

3. Start running through the test you’ve planned

4. Everyone in the group should try to be a facilitator at least once

A collection of notes detailing usability problems found in the product

USABILITY TEST STEPS

TURNING DATA INTO ACTIONS!78

What to do with all the data?

‣ Identify changes with the biggest impact & smallest effort as a team

‣ Find the “low-hanging fruit”

‣ What has impact on the bottom line?

‣ Put everything else in the ice-box

TURNING DATA INTO ACTIONS!79

Identifying key findings

High-priority: people fail, or abandon the task

Medium: people succeed but are frustrated and unhappy

Low: people would enjoy the app more if...

Tip: You can’t fix everything. Pair usability priority with business needs and product roadmap to find the fixes with the biggest impact.
