Hi all,
I was wondering how can we provide upfront initial time estimate of a project, assuming that a high level product backlog has been prepared. Consider that the client is interested in overall time it will take to build the entire thing, while being open to incremental shippable deliveries. What does Scrum say about it ? Is referring to historic records the only way? what if the organization do not have a similar work done before. I apologize if this question has been asked before, but I was not able to find it.
