The concept of this study was to explicitly define the characteristics of Process Documentation (PD), a unique type of record keeping system. The PD is a process of lessons learned-centric piloting approach which is a neologism in Social Science research. The PD moves forward “anti-clock-wise” direction and generally applies to humanitarian agencies in support, care and emergency relief programs to deliver basic services to needy people. The PD was first used in the Philippines in 1978, but applied in Nepal after peace accord 2007 to unite, reconcile and integrate the society through interfaith peacebuilding (IP) initiatives. The objectives were to document the process of the IP and analyze change perceptions contributing to transforming the ongoing conflict. The method led to interviews, storytelling, FGDs, observation and participation. The PD of IP generally functions through End-to-End Lifecycle that is organically similar to an ecosystem. Interfaith is not a religion, but a glorious art of symphony that makes a passage for peace, harmony, co-existence and friendship (for more, either visit in https://www.transcend.org/tms/2018/08/process-documentation-of-interfaith-peacebuilding-cycle-a-case-study-from-nepal/) or find attachment.
