The OOPP is a planning tool which has been one of the subject courses in Master
Training Program in Community Nutrition at our institution. It has been associated with
GTZ, as one of the user and as the first organization to have introduced it into our
curriculum within more than a decade ago.  With this handbook, OOPP is positioned
more appropriately as a planning tool for a project, rather than, a program.  By this,
readers and users may benefit the usefulness of the tool in the application of project in
nutrition, health and other related sectors.   

I would like to sincerely thank to the team who worked so diligently to bring this
handbook to completion.  I also thank the team of the second edition who has made
significant editing and updates to improve the consistency, and thus, the clarity of the
handbook content.
