Present a Lunch and Learn[edit]

Here is the emergent process for scheduling a lunch and learn.

  1. Check your calendar, you should have a standing Lunch and Learn invite every 2 weeks
  2. Find the next calendar event that does not have a speaker
  3. Add the date to this page, along with your name and the subject of your lunch and learn
  4. Modify the calendar event with information about your talk — your name, the title of your talk, and a link to your slides (if there are any)
  5. Store slides in the shared Engineering Productivity/Lunch and Learn folder on Google drive OR post them publicly on the internet or on wiki and link them from this page.
