What is User Experience?

And this

The first requirement is to meet the exact needs of the customer, without fuss or bother . Next comes simplicity and elegance that produce products that are a joy to own, a joy to use . True user experience goes far beyond giving customers what they say they want, or providing checklist features. In order to achieve high-quality user experience in a company's offerings there must be a seamless merging of the services of multiple disciplines, including engineering, marketing, graphical and industrial design, and interface design . User Experience "User experience" encompasses all aspects of the end-user's interaction with the company, its services, and its products.

Reality Austin Allegro 1973 - 1983 - Britain's worst car ever One example of its poor construction was that it was more aerodynamic when traveling backwards than when it was being driven forwards

“ horrendous reliability, absurdly bad fuel economy, terrible handling and the acceleration of a grapefruit” Hummer H3 2008 - Worst car of the year

Software is not different

Many software products have no target audience www.lively.com social network closed by Google in 2008

Many software products have no target audience

Most products are “rude” with dumb errors screens

Most products are “rude” with dumb errors screens

Developers assume that users are technically-savvy

Software products are often have unpredictable behavior

and bad UI

and bad UI

Can it be even worse?

Yes!

Do you think TargetProcess is a lucky exception?

We have

Outstanding usability

Self explanatory UI

Intuitive Navigation

Fantastic Forms

Super Consistency

Sooooo Stylish UI

And elegant simplicity

Anybody knows this screen?

So what the problem? We don’t know our users (how they are going to use product, why they choose our product) There is a conflict between developers’ priorities and users needs (developers focus on simple code, not on users needs) There is no process that help us to understand users (can’t be delegated to users or developers)

There were different times

Goals motivate users to use product in a defined way It’s quite hard to discover real users goals UI is an artifact that is not directly connected with users goals, it’s an impediment Goals

Goals Senior C# developer? Scrum Master in distributed team? Product Owner that shares 3 projects? Smoke Tester? Desperate Artist? Inglorious COBOL Developer?

Senior C# developer?

Scrum Master in distributed team?

Product Owner that shares 3 projects?

Smoke Tester?

Desperate Artist?

Inglorious COBOL Developer?

1. Desirable (I want this thing!) 2. Technologically possible (teleportation still not invented) 3. Valuable (we can make money!) Product success

Part II Tools Tools

Interaction Design Task-Centered Design sucks (“What are the tasks?” is a stupid question) Activity-Centered Design is better (focus on user activity) Goal-Centered Design is best (why user do this? our goal is to make user more effective with help of UI)

Help to define what product should do and focus on real people needs Provide patterns to solve problems Communicate with team members, users, etc -> common language Evaluate efficiency of the solution (we may feel they pain and problems) We may include buyers persona (they usually have different goals)

Scenarios

Context scenarios Goal scenarios User Stories one day of life focus on a goal Scenario describes situation in a context

Working with Scenarios Who involved? What triggers the scenario? What happens? What is the result? Imagine magic interface - no borders! Generate new ideas For TP we may create current and future scenarios to see real improvements

Wireframes

Wireframes Fast way to prototype UI Create several (at least 3) completely different sets of wireframes Test wireframes on users Create working prototype (HTML)

Create several (at least 3) completely different sets of wireframes

Test wireframes on users

Create working prototype (HTML)

Sketch Boards Draw several screens on one board Visualize users navigation and flow Quickly evaluate ideas

Sketch Boards

Prototypes “clickable wireframes” Required for usability testing and proof of UI design Good as UI documentation for developers HTML, Visio, other tools

UX Principles People think that beautiful interface is more usable Don’t make people feel stupid. #1 principle in UX design First define WHAT product should do, only then define HOW it will do that Less UI (less navigation, less windows, less actions) Design for flow

People think that beautiful interface is more usable

Don’t make people feel stupid. #1 principle in UX design

First define WHAT product should do, only then define HOW it will do that

Less UI (less navigation, less windows, less actions)

Design for flow

Lipstick on a pig Improve look and feel of a broken product to promote and sell it

That is not what we want to do (but tried...)

Our goal is

Killer UX Point-and-shoot :)

Lets add UX into our dev.process

UX group (max to 5-6 people, including designer and PO) UX culture (everybody should have basic knowledge in UX and focus on users goals) UX process - personas, scenarios, wireframes, prototypes, UX stats, usability testing, perfect design Full customer’s life cycle UX (web site, support, etc.)
