  17. 17. Scale of a Single Pattern How to make a Printable View…
  18. 18. Scale of a Single Pattern How to make a Printable View… This bit
  19. 19. Our valiant attempt…
  20. 20. We worked
  21. 21. We slept
  22. 22. We worked some more
  23. 23. We carefully rehydrated

  28. 28. Oh, that’s not good <ul><li>2 * patterns in </li></ul><ul><li>6 months </li></ul><ul><li>< 5 percent </li></ul>*Note: They weren’t even done
  29. 29. Clearly, this is not going to work
  30. 30. What did we do wrong? <ul><li>External Research Only – We looked at examples but didn’t validate them internally </li></ul><ul><li>Detail & Scale – We went way too deep, way too early </li></ul><ul><li>Scope Creep – “Oooh, and wouldn’t it be cool?!” </li></ul><ul><li>Incomplete Taxonomy – We didn’t have a complete idea of what we needed to document </li></ul><ul><li>No Prioritization – Printable View?

  34. 34. Agile Pattern Creation Start small Go wide, get coverage across all patterns Add detail when necessary
  35. 35. Agile Pattern Creation Check progress regularly Share with our intended audience and make changes Listen to suggestions
  36. 36. Agile Pattern Creation Create something nimble – easy to create and easy to update Software changes all the time Designs change all the time

  40. 40. What Makes a Good Postcard Pattern? <ul><li>Use the “Goldilocks” Principle </li></ul><ul><li>If the pattern doesn’t fit on a single page, consider breaking it apart or reducing the amount of detail </li></ul><ul><ul><li>You can always add detail later </li></ul></ul><ul><li>If the pattern doesn’t fill a single page, consider grouping it with other similar elements – e.g. common web form elements </li></ul><ul><ul><li>You can always break it apart later </li></ul></ul>Rule #1: Must fit on a single 8.5” x 11” page
