Graphical methods were compared and contrasted with more rigorous statistical techniques. It was found that the graphical methods could give a useful insight of possible trends and also helped identify and track the influence of external shocks to the system. The application of regression analysis was less successful with no statistically significant relationships detected. It is concluded that the flexibility and adaptability of the graphical methods are likely to be more useful to project managers. %I Loughborough University
