  • sounds like complexity is kind of a relative measurement that is going to give an idea how much of effort that we should put into. Isn't it? Commented Feb 18, 2015 at 15:46
  • It is a relative measure, and yes it just gives a rough idea or indication. Complexity isn't exactly the same as effort but they can be equated. Something can be very complex or very simple. Which might mean it is a lot of effort or very little. The two concepts can definitely be equated but they are slightly different. Commented Feb 18, 2015 at 16:47
  • Don't worry about it too much just give the estimate you think fits best. You'll need to explain your thinking but once you've done it a few times with the team you'll get the hang of it. No estimation technique is perfect but I do think story point estimates are better than time estimates. Commented Feb 18, 2015 at 16:49
  • I think this answer illustrates my gripe with story points: they conflate complexity with time. Time and complexity often correlate, but in my opinion there is no causation there. I have worked on some extraordinarily complex requirements that took an hour, and I have worked on week-long mind-numbingly tedious but simply requirements. Sprint poker does not differentiate. I have e.g. 8 days in a sprint. I need to know how much time a requirement takes in order to know if I can cram it into that sprint. Knowing the complexity is fine, but that does not tell me what I need to know. Commented Feb 18, 2015 at 19:11
  • It does tell you that once you've figured out how much complexity you can fit into 2 weeks - which can definitely change but if you need an indicator and i think it is more accurate than time estimates Commented Feb 18, 2015 at 21:17
