a social network site requires remote evaluation

a card sort improves breadcrumbs

an Agile team is bad for a marketing site

<design pattern> requires <process pattern>

best practices on steroids!

• is a general, repeatable solution to a commonly-occurring problem

• is either proven effective or seen often enough to be considered worth following

• is not a finished design that can be transformed directly into code

<design pattern> examples

• Shopping cart(summary of items and prices, add, delete, details, checkout, )

• Paging mechanism(number of results, number of pages, current page, current results, next, previous, first, and last page)

• E-commerce site(product catalogue, search, user account, shopping cart, marketing, ordering process, product configurator, trust information)

<design pattern> collections

• a library of patterns• structured, layered and linked (a pattern language)

Examples• Martijn van Welie's Patterns in Interaction Design

http://www.welie.com • Yahoo! Design Pattern Library

• describes sequences of general techniques, tasks, actions

• works at the task, stage or phase level

• consists of reusable building blocks

• allows an organization to tailor a process

<process pattern> examples

• team review task(announce review, distribute deliverable, review with team, publish report, update & re-distribute deliverable)

• usability evaluation stage(set goals, determine method, create prototype, create scenarios, recruit participants (optional), perform test, report findings)

• inception phase(gather requirements, write business case, set scope, identify actors, asses risks, plan, estimate, adapt process)

<proces pattern> collections

• a library of patterns• structured, layered and linked (a pattern language)

IconProcess: UX Workflow

“The project team transforms the Vision or Business Concept for the application into concrete requirements, visual designs, and prototypes through roles, activities and artifacts defined in the IconProcess User Experience discipline.

This discipline's participants analyze users' needs and then define a corresponding digital experience using a mix of technical and creative skills.”

IconProcess: Develop IAPurpose:- Organize the website's content and features into a logical structure of the whole website - Define page structures for individual pages or page types (i.e., templates) - Develop navigation mechanisms to facilitate users' access to information and functionality

How to Staff: In early iterations, the Information Architect collaborates with the Content Manager to create the initial Site Map based on the Business Concept.As the team clarifies the requirements by working with stakeholders, the Information Architect and the Requirements Analyst work together or frequently review each other's work to refine the evolving Site Map and Wireframes as the Requirements Analyst refines the requirements.The Graphic Designer and User Interface Prototyper give the Information Architect valuable feedback on the Wireframes and interaction design while applying the visual design to the Wireframes and building the prototypes.The Information Architect uses that information to further improve the information architecture.

• are different

• yet similar

• give a feel for the work

• can be linked

the patterns are different

• <design patterns>describe context of use when is it good for the user (and the business owner) to apply this pattern?

• <process patterns>describe context of designwhen do what types of designers deliver what (to the business owner) and how?

but the patterns are similar too

• both are driven by “forces”("users want..." vs. "the project requires...")

• both describe pre-conditions("the solution requires..." vs. "teams want...“)

• both describe post-conditions(“this makes users feel…” vs. “this makes sure teams…”)

• both refer to team skills(“an IA designs…” vs. “an IA designs…”)

patterns give a feel for the work

• <design pattern> collections tell you how much you have to design from scratch and how much can be reused

• <process pattern> collections tell you what activities are necessary and who should perform them

in the strategy layer you use

• <design patterns>experience patterns, site type patterns

• <process patterns>write business case, calculate ROI, design thinking patterns, perform user research

in the scope layer you use

• <design patterns>entire collections to see what's already there, main user concept, mental model

• <process patterns>run scoping workshops, estimate, plan releases

in the structure layer you use

• <design patterns>site type, main navigation, search, search results, index, sitemap, related content, local navigation, wizards

• <process patterns>perform requirements workshops, perform concept test, perform card sort, create content inventory, create controlled vocabulary, design reviews

in the skeleton layer you use

• <design patterns>layout, visual hierarchy, tone of voice, action buttons

• <process patterns>apply eye tracking, perform usability test

in the surface layer you use

• <design patterns>mood, grid, layout, eye direction

• <process patterns>user research, create moodboard, create mockup, create styleguide

the patterns can be linked

• <design patterns> are used/generated when applying a <process pattern>Examples: review process, user research

• <process patterns> are useful when applying a <design pattern>Example: breadcrumbs

<process pattern> : review

what if we could

• browse <design pattern> collections and find <process patterns> associated with them

• browse <process pattern> collections and find <design patterns> associated with them

• browse pattern collections to get a feel for the work in each phase

what if we gathered data on

• which <design patterns> work best for which site types

• which <process patterns> work best for which team compositions

• which <design patterns> work best with which <process patterns>

• which design & process pattern combinations create the best sites

then we could

• apply that data when composing:- designs,- design processes- design teamsfor all types of sites

• explain to our clients:- why we design what we design- why we design how we designand have statistical proof

“in New York State, architects have developed a database on roof design and performance.The database tracks a growing number of the state's 10,000 buildings, recording variables of location, design conditions, specified components, testing results, and the history of problems and their solutions.By correlating design information with performance problems, the architects identify patterns of success and failure.”

challenge

“How interesting it would be to go even deeper in the analysis: what were the organizational patterns associated with the roof successes and failures?Which arrangements can detect crucial errors and correct them, and which cannot? The answer to that question could affect all of architecture.”

“in Barcelona, Information Architects have developed a database on infospaces’ design patterns and process patterns. The database tracks a growing number of Europe’s millions of infospaces, recording variables of location, design conditions, specified components, testing results, and the history of problems and their solutions.By correlating design information with performance problems, the Information Architects identify patterns of success and failure.”
