A pair of geographically diverse projects will determine whether Starbucks can fix a slowdown that's eroding its reputation as a master of mobile technology.

It is seeing some momentum from mobile ordering, which accounts for 10% of all Starbucks transactions, but it still has a lot of work ahead of it.
