This paper uses Overseer as an example of a continually developing decision support tool and highlights some of the key scientific and operational challenges in building and maintaining such a tool. These include: maintaining a strong science base to the model; maintaining the correct balance between simplicity and complexity; maintaining and upgrading software to maintain reliability; providing users with support so that the model is applied correctly.
