The key feature of a research programme is that it attempts to provide conclusive answers to a significant issue, or a set of closely interconnected questions, rather than one small piece of the jigsaw puzzle fitted into place. When completed, it should provide a significant addition to knowledge and understanding of the topic - a watershed or milestone. A successful research programme constitutes a major step forward at the very least, and may potentially completely re-shape the definition of the issue and public understanding of it. A research programme involves great expectations and hence a great deal more thought and care in its design (but not necessarily more money) than a single project, however large.
