Deciding whether a story(task) is small or large requires some investigation of that story(task). And this investigation must be assigned to one team member - not to the whole team. Right? I need to organize the team's work so that they analyse the tasks (from a backlog) and provide an objective value of complexity for each task (kind of a story point) before starting a sprint. So that we can reliably estimate an amount of work we can plan for a sprint. Using the statistical method (the time spent during the previous sprint) just doesn't work good enough for us.

I currently work on a development project. We try to use Scrum. I asked team members to analyse and estimate tasks for a new sprint. The estimations that they've provided are obviously random.
