The mHealth Assessment and Planning for Scale (MAPS) Toolkit is a comprehensive self-assessment and planning guide designed to improve the capacity of projects to pursue strategies that increase their potential for scaling up and achieving long-term sustainability. MAPS is designed specifically for project managers and project teams who are already deploying an mHealth product, and who are aiming to increase the scale of impact. External parties seeking to understand the maturity and value of mHealth projects may also find value in using the Toolkit jointly with projects. --from the World Health Organization publications website, 2015
