What Are Patterns For?

• Avoid reinventing the wheel

• Promote a familiar user experience for our customers

• Free up designers to do innovative leading-edge work

• Now shut up and do your wireframe.

So What Exactly is a Pattern?

• The essence of a pattern:• Problem (what does the user want?)

• Solution (how to meet the user’s needs)

• Context (when to use it)

• Examples (pictures, links)

• High-level, based on principles

• Linking to related specs and documentation (which can change more frequently)

- -

How our user experience designers contribute

• Check the library

• Give Feedback

• Suggest a Pattern

• Help write or review a pattern

- -

Give feedback…

• Comment on patterns

• Make suggestions about how to improve them

• Complain about patterns that seem out-of-date

• Discuss them on our design lists

• Edit a pattern

• Ask me for help

- -

The Burrito Trap

- -

Suggest a pattern…

• Looked for a pattern and couldn’t find one?

• Developing something cool on your property?

• Notice a (needless) inconsistency across Yahoo! sites?

• Notice an emerging trend here or elsewhere around the Web?

- -

Help write or review a pattern

• I post requests on designer list

• Designers can just review drafts or offer suggestions

• Designers can submit diagrams or wireframes or templates

- -

I interview the designer: the debriefing

• We sit down for 45 minutes

• They talk me through a solution

• They point me to their specs

• I write a first draft

• The designer gives feedback

- -

The Pattern Writing Process

• Context

• Problem

• Solution

• Example

• Name it!

- -

Examples and Illustrations are Key

- -

Editing and Reviewing

• We invite volunteers to review

• I do some editing

• When ready, we ask the “official” pattern library reviewers to weigh in

- -

Rating the Patterns

Assign a “level of adherence” rating:

• Working Solution

– Recommended starting point for any new design

– Designer may adapt as needed

• Best Practice

– Strongly recommended

– Requires manager’s permission to deviate

• The Yahoo! Way

– Mandatory

– Requires extremely high level permission to deviate

- -

Keeping Patterns Fresh

• Age-dating patterns (credibility, authority)

• Quarterly review of existing patterns

• Tuning in to user feedback

• Revision and Upkeep

– Marking patterns as under re-review

– Recruiting authors to update or supplant

• Retiring obsolete patterns (quality over quantity!)

- -

Peeve-Driven Patterns (Fixing Antipatterns)

- -

Pattern Ownership

• Pattern Lifecycle

– Submission / Suggestion Process

– Writing

– Editing

– Reviewing & Rating

– Freshness

- -

Yahoo! Pattern Library 2.0?

• Truly open: two-way interaction

• Support our open, social platforms

– as part of YDN give designers and developers UX tools

• Getting beyond old-school IA

• “My Patterns”

– Patterns I’m writing, I wrote, I contributed to

– Patterns I love, I use a lot, I have trouble finding

- -

Who edits and reviews?

• Editing

– Pattern librarian

– Volunteer contributors

– Ready for review

• Reviewing & Rating

– Small team review list (senior ID leaders and enthusiasts)

– Regular review/release cycle

– One week for comments (with wiggle room)

– Back to the drawing board

– Quicker review of revised patterns (to verify that identified issues have been addressed)

- -

The importance of examples

• Examples as references

– As used on your site

– Reference implementations

– Exemplars from elsewhere online

• As a survey / auditing / research tool

– Make galleries of screenshots

– Compare / contrast

– What works, what doesn’t

- -

Visual examples

• Nobody likes to read specs!

• A picture is worth a thousand bullet points

• Designers are visual. We like diagrams, illustrations, concepts, examples, pictures!

Wireframe and diagram stencils

Give designers tools that make it easier to adopt the patterns:

- -

Code is key

• Pattern adoption works best when engineers have reference implementations, examples, and running code

• Developers can then build solutions out of components just as the designers build experiences out of the patterns

• Pattern + Stencil + Code = a very useful building block
