The document discusses barriers to wider participation in OpenStreetMap (OSM) and strategies for overcoming them. It analyzes OSM tasks like inputting data, accessing data for use in GIS or mobile apps, and updating data. OSM currently relies mainly on computer-literate users, but to grow it must engage less technical groups. Usability engineering principles can help make OSM's tools and processes more learnable, efficient and satisfying for diverse users as the project matures and technical complexity increases. Developing applications tailored for different user types at various skill levels can help newcomers gradually build skills and contribute long-term.
