User Centric Design (UCD)

Basic defintions:• User Experince (UX) is about

how a product works when a person comes in to contact with it and has to use it.

• UX quality is measured by the level of satisfaction an average user gets from the product.

• A good UX encourages users to “convert“ to the next level (e.g. subscribe to the site or buy a product). Conversion rate is a common way of measuring the effectiveness (Return of Investment, ROI) of a user experince.

• A bad UX drives people away from your site, makes them feel stupid, angry or frustrated.

• User Centered Design (UCD) puts the intended users of a product at the centre of its design and development.

• UCD does this by taking the user into account every step of the way as the product is being developed.

• Involvement of the users are carried out in an iterative fashion.

UCD Basic Workflow

The development and involvement of the users are carried out in an iterative fashion, with the cycle being repeated until the project‘s usability objectives have been attained. The primary steps are:1) Concept, 2) Research, 3) Prototype, 4) Test, 5) Build/ amend 6) Testing/ building until right, 7) Launch, 8) Post Launch Testing.

5 Planes: Elements of UCD• The Five Planes Model

provides a conceptual framework for talking about user experience problems and the tools to solve them.

• The five planes are built from bottom to top, from an abstract level to a more concrete level.

• Decisions made on the lower/ higer planes can have ripple effect in both directions.

Page 5: User centric design (ucd)

5 Planes: Elements of UCD• The 5 Planes are devided in to:• Strategy: define sites & user

centric goals, do research (interviews, Focus groups), create Personas).

• Scope: decide content & functional features, create user stories & scenarios.

• Structure: develop site structure, information architecture, use Card sorting & user stories. Site mapping in Core Process terminology.

• Skeleton: wireframes, navigation, placement of photos, text, buttons etc.

• Surface: visual design, concept, colors, mood boards etc.

• Work on the next plane shall start before the work on the previous plane is finished

User Centric Strategy• “Do we know what the

problem is, and does this (product, website) solve the problem for those that will use it?”

• “What should the user be able to do?”

• Our goal is to improve efficiency: Help people work faster and help them make fewer mistakes.

• First step is to define the average user:

1. Create attributes list (Primary goals for visiting the website, Roles: job seeker, information seeker, client etc., Demographics: sex, age, income, single, married etc., Experience: education, tech know-how etc., Organizational: type of job, type of company user works for etc.

2. Prioritize and define what attributes are important for user/ sites goals.

3. Describe segments or user groups to do research on.

UCD Research Methods• Research techniques can be

devided in to qualitative (insight) and quantitative (validation) research.

• Qualitative research is about discovering new things with a small sample size.

• Examples of qualitative research are: 1) Focus groups (intended/ actual users share thoughts, feelings, 2) User interviews (1 to 1), 3) Field studies (observe, asking users in working situation),

4) Card sorting (suggest structures/ categories) and 5) Usability testing (collect data from people as they use, e.g. think-aloud test).

• Quantitative research is about testing something with a large sample size.

• Example: Surveys and Site traffic or log file analysis.

• Quantitative research is better at telling you what is happening, qualitative why it does.

Personas: Tool for UCD• Another way to look at UCD

research is to study what people say (goals & attitudes they have) versus what they actually do (behaviors).

• When research is finished we create personas, description of typical users.

• By building a fictional representation of the users we are able to empathize with them and understand their needs.

• Personas are marketing-targeted (purchase motivations) or interactive (usage behaviors).

Page 9: User centric design (ucd)

Personas: Tool for UCD• Personas must be actionable.

“What are their goals, attitudes and behaviors?”, are the basic questions we should ask ourselves.

• Persona description should include: Photo (not posed but natural) – Name (normal one) – Age – Location (for cultural and behavioral differences) – Occupation – Biography (facts, anecdote, stories that makes the persona more real).

• It might also include: Education – Salary – Motto – Online/ offline activities – Loyalty towards a brand – Tech/ Computer knowledge – Social network behavior – Motivation to use brand – User goals.

• Storytelling: Creating stories about the personas helps us cast a more meaningful vision of the project.

• Single line stories that include the role of the user and the activity they wish to perform.

Practical Example of UCD • Help and video tutorials on

how to use website.• Make obvious what’s clickable

and what’s not (links, buttons).• If possible stay in one window.• Printer friendly version.• Create shortest paths to

completing tasks. • Include a site map or

breadcrumbs to show users were they are and were to go.

• Use good space between lines (1.5) and all elements.

• Write short paragraphs and use everyday words.

• Have good readability. Large enough body text, high contrast betwean text and background.

• Have excerpt and big headings for light scanning.

• Have Content and links go-down and go-up in long pages.

• Use small file graphics so they download quickly.

• Use meaningful and consistent elements across site.
