World Vision (go to www.WVI.org) is a global Christian relief, development and advocacy organisation dedicated to working with children, families and communities to overcome poverty and injustice. It is a large complex organization that has produced many tools for facilitating, monitoring and evaluating Transformational Development. Full disclosure: from 1985-2011 I worked as an evaluator in WVI, and was involved at different levels in developing some of the tools in their early versions.
I recommend that you explore the large number of resources that World Vision has made available to anyone involved in some way with community development intended to create opportunities for individual and social transformation as revealed in scripture.

I will highlight some resources from a TE perspective in other posts.
