- Who decides on while agile frameworks works best for a team? Is it Development team / Portfolio Manager / Management / Scrum Coach? who? IMO: its the decision of a Development team as they are the one's doing the delivery.
Some of the factors that I consider during these meetings are:
Why would you want to "decide on" a methodology, rather than evolve one?
If you're in an existing organization, you most likely have a set of practices and techniques that have worked on previous products or projects. If you're in a new organization, you may have past experiences or be a very small team that doesn't fit into a mold of any of the well-defined processes. Why would you not start with where you are now and evolve, using frameworks and good practices as a guide for experimenting?
