This page records a log of the team’s work, thinking, discussions, pains, joys, events, and experiences that happen on a daily basis. It’s supposed to be a kind of Stream of consciousness that can later be searched, analyzed, reviewed in more formal retrospectives.

Rules:

• Log days in reverse chronological order, recent first

• When the stream is getting too big, such that github refuses to render do the following:

  • extract biggest logical section (half-year or quarter) out of this into a correspondingly named Logbook-Year-Hn.md or Logbook-Year-Qn.md page
  • update links on top of this page to make it easier to navigate try to fix all links in the wiki at least
  • notify the team

• Move (and link) recurring sections to relevant dedicated pages.
