I am trying to come up with ideas of how to forecast work for a team before it is formed. Management is asking how many scrum teams will be needed to complete a project within 12 months.
Currently, the project has not been approved for funding. Before funding can be approved management wants a high level assessment of the needed workload and how long it is estimated to take to complete.
How would you go about estimating work when there is no scrum team in place to size it? Who does the estimating of the work?
Appreciate thoughts and ideas
