Successful and sustainable projects require a sensible project design which clearly identifies what will be achieved and how it will be achieved. This may appear self-evident, but some well intentioned projects are started without a realistic project structure. The absence of a workable design typically leads to confusion over the roles and responsibilities of each partner, avoidable duplication of effort, misuse of limited resources, indeterminate measures of success, and, worst, a higher possibility of "drift" during implementation away from the original objective of the project.
