  1. Pattern Library Basics Design Patterns Research Group

  2. Knowledge capture and transfer • How do organizations record important information for later use? • How do they record information about design, including the design of processes? • This is part of the broad field of knowledge management • Pattern libraries are a tool for knowledge management

  3. Knowledge capture and transfer Face to face • Interviews • Observation • Apprenticeships • Training Programs Documents • Handbooks • Policies & procedures • Style manuals • Project notes/records • Minutes of meetings • Regulations • Design patterns • Etc.

  4. Applicable knowledge transfer situations • Doctors joining staff of a hospital • Engineers (etc.) joining an ongoing project in their organization • Contributing to public knowledge by government agencies, non-profits, and companies promoting their skills. For example: Usability.gov (U.S. Department of Health and Human Services) • LabelPatterns.org

  5. Design patterns and pattern libraries • What constitutes a design pattern? How does a pattern differ from other guidance? • What constitutes a pattern library (language, collection, etc.)? As a default we will talk about “pattern libraries”

  6. What is a design pattern? • Design patterns are enhanced guidelines that follow a problem-solution structure • They employ standard components (drawn from a wide superset) • They address a design problem with no obvious solution (a heuristic problem). You don’t write a pattern for calculating the circumference of a circle). • Design problems pertain to both artifacts and processes.

  7. What is a design pattern? • They are usually part of a library of design patterns

  8. What is a pattern library? • A collection of patterns dealing with one general (or specific topic) • They exist in various media—print, web, wiki • They may be public or proprietary • Various means for finding desired patterns: • Browse • Database query • Search • Hyperlinking • Pattern libraries may contain other kinds of content

  9. What is a pattern library? • Pattern libraries may contain other kinds of content

  10. When are pattern libraries a worthwhile form of knowledge transfer? • Heuristic vs. algorithmic problems • Manageable complexity of problem space (sweet spot) • Reference function (non-linear access) Pattern library for K-6 math? Pattern library for writing a novel? Pattern library for website design? Pattern library for consumer-information labels?
