How we Size/Estimate

  • We favor estimating relatively, more than absolutely
  • Using modified Fibonacci sequence:
    • 1, 2, 3, 5, 8
  • Story points are unit-less
  • All items are estimated relative to a baseline that the team understands well
  • Story points simultaneously capture
    • How much work is there?
    • How hard is that work?
    • How much risk is there?
