Workgroup 3 focuses on communication, knowledge management, and learning within the PPP-ISWM project. The group identifies various training and coaching methods like e-learning, face-to-face sessions, and expert exchanges to share project information, training materials, and experiences between candidate PPPs, learning partners, and implementation organizations. Both digital tools like online discussions, document sharing, and a project website as well as print materials will be used to facilitate information flows and networking between stakeholders. The group also outlines concepts for mentoring processes and information flows when coaching organizations and implementing PPPs.
