The Product Owner asks the Scrum Master's recommendation; when the the Scrum Team waits for a specific component software which has to be supplied by external supplier & without that there wouldn't be enough work for the Development Team to perform in the next Sprint.
As a Scrum Master what would you opine to the Product Owner?
> Make the Product Owner to Recall that his one of the responsibility is to maintain a consistent flow of value which must reflect in the ordering of the Product Backlog items
> Recommend the Product Owner to re-order the Product Backlog items so that the work that needs the involvement of specific component software can be taken up in the next Sprint
> Recommend the Product Owner to order the Product Backlog items in such a way that it maximizes the utilization of Development team effort
Note - I feel the 2nd option makes sense, what's your point of view!
