The Breadth of UX
According to ISO, UX encompasses the following – before, during, and after use:
• Emotions
• Beliefs
• Preferences
• Perceptions
• Physical responses
• Psychological responses

Convenience + Design – Cost =
User Experience

Why should developers care?
Without users, our software has no reason to exist.
More happy users means better chance of getting them to recommend our software
to others.
While designers can make things look visually appealing, at the end of the day, if the
functionality is awful, people will get frustrated and stop using a product.

Tying UX to the
Software Development
Phases

Software Development Phases
Analyze
Design
Develop/Implement
Testing
Evolution/Finalize

Analyze
Understand the problem that needs to be solved

To Analyze….
Figure out the content of the problem and how to tackle it
Get a better understand of the end users through user research and interviewing
Brainstorming ideas on the problem
Gathering requirements in terms everyone understands

Brainstorming
Mind mapping tools

How These Help Developers
Mind maps allow the developers and business to lay out the scope of an application.
They also allow developers to see possible growth of an application that may not have
been originally anticipated. Brainstorming with others can lead to other ideas coming
up.
Site maps help web developers to see the layout of a website and can serve as a
checklist of the progress of site development.

Tools
Mind Maps
Xmind
Freemind
Flows
Dia
Site Maps
Balsamiq

What are personas?
Fictional characters based on real users
Composites of research
Usually presented in 1-2 page documents

Personas
José
Business
Owner
Irene
Older
Resident
Sarah
Younger
Resident

José
Business Owner
What are the city’s demographics?
Are they appropriate for me to
bring my business there?
What incentives do they have for
businesses?
Are there good networking or
community opportunities for
promoting my business?

Irene
Older Resident
Are there any senior programs for
me to participate in?
What doctors and hospitals are
there?
Are there parks or places for me to
walk?

Sarah
Younger
Resident
Where can I learn about the local
school system?
Are there any summer recreation
programs for my kids to participate in
when they’re older?
How safe is the city for my kids to play
in?
What’s the diversity like of the
residents in the city?
Are there parks for my kids to play in?
Will they be safe there?

Assigning personas to screens helps us to make sure the functionality is designed
appropriately.
Sometimes, developers become empathetic with the personas, putting themselves in
the personas’ positions. This helps them to realize flows easier.

Features and
Requirements
Gathering

Features
During brainstorming, break a project into features.
Use the features to help write the code and determine tests.
Write the features in English with gherkin.
Consistency
Works on multiple platforms

Given-When-Then Cadence
Consistent wording to describe a scenario
Given this known situation
When the user does something
Then something happens

Writing features in English bridges the gap between business and tech teams.
These scenarios cover the use cases for the app, defining points to be tested.
The feature files map down to code, which means that the developers can use these
for automated testing.

Tools
Behat (PHP)
SpecFlow (.NET)
Cucumber (Ruby, gherkin syntax)
Cucumber-JVM (Java, including Android)

Design
Draw out your understanding of the problem and your
idea on how to solve it

Designing a solution
Things that need designing…
User interfaces
Interaction design
Accessibility experiences
Prototyping
Processes
Tools that we can use as devs include…
Balsamiq Mockups
Wireframes.org
Pencil
Dia

Wireframes.org
Built in templates
Wireframes, flow charts, etc.
Runs right in the browser

Wireframes help developers see possible UI layout and designs, making it easier to
conceptualize the app. They also help the business see these as well.
User Flows help the developers understand the process that they are improving or
developing. This also helps the business to see their process and identify pain points.

Tools
Balsamiq Mockups
Pencil
Wireframes.org
Lucid Chart

Develop/Implement
Write the application or script to solve the problem

Things to consider in development
We want as few clicks and as little thinking as possible
If everything is set up well, you can take a TDD approach.
Using the gherkin from the “gathering requirements” stage
Transition by writing a failing test for a feature
Then make the test pass with the appropriate code
Keep it simple and easy to use

The steps in the feature file help the developers to see the process of how the app is
getting used.
Having the code documented in feature files allows the developers to write as little
code as possible to get the job done.

Testing
Make sure what you create is working as expected in
order to solve the problem

Things to see in testing
Test to make sure the code is covering all the features – can be done in automated
testing
Have users test and report issues – exploratory testing
Use focus groups to help test the app, and use heat maps and analytics to see how
people are using the app

Google Analytics
Track information about
visitors including:
Time on site
Pages visited
Location
Traffic source
Browser usage

Feedburner
Used for tracking
RSS feed
subscriptions
Great for
tracking people
who read blogs
in a feed reader

Heatmaps help developers see what parts of their UIs are getting used the most. This
can help them identify problem spots or possibly suggest layout improvements.
Analytics can help them identify their end users’ environments, allowing them to
develop appropriate experiences that scale well to the various environments.
- Including different browser types
- Including different platforms (phones, tablets, laptops, televisions, etc.)

Tools
Heat Maps
Free Website Heatmap Generator
ClickTale
CrazyEgg
ClickHeat
Analytics
Google Analytics
KissMetrics
Feedburner

Evolution/Finalize
Run through what’s done and release it and improve
upon it

Development is cyclical. Use
these tools to improve your
productivity and the quality of
your work!
