From the Google Nonprofit Blog:
"Google Maps Coordinate is a workforce management tool that allows organizations to quickly and easily assign jobs to field workers, improving operational efficiency and communication. Coordinate lets a dispatcher team have real-time visibility into the locations of the field workers, and they can send job assignments directly to their mobile devices. In the field, mobile workers can accept jobs, add relevant information to each job assignment, keep their dispatchers updated, and work more efficiently knowing where all the other field workers are."
