This document provides an overview of developing a behaviour change communication (BCC) strategy in multiple chapters. It discusses that a successful BCC strategy follows a systematic process including analysis, budgeting, strategic design, developing and pre-testing messages, implementation, and monitoring and evaluation. It also summarizes the "Goli ki Hamjoli" campaign in India as an example of an effective BCC intervention that addressed myths around oral contraceptives through formative research, direct and interpersonal communication, and a mass media campaign targeting different audience stages.
