This book has been designed as a tool for the persons forming and nurturing Self-Help Groups, to enable them to train members and office bearers of the groups in the concepts, processes and procedures of group functioning. It has been written in very simple language for easy understanding by grassroots level functionaries. The book is divided into 14 chapters. The first four modules are devoted to explaining the concept of Self-Help and the principles of group functioning and points that need to be attended to while forming groups. The field worker can use these modules at the stage of group formation. This is followed by different topics that a group should understand for management of the collective effort. The field worker can use each of these modules when attending the group meetings.
