From this data we can derive the information:
• Required transfer rate (pages left / time left)
• Actual transfer rate (pages transferred/ time spent)
As the project progresses, we should gradually get a more and more accurate idea of the estimate of pages
If the transfer rate goes down, it could be because staff have been taken away to work on other tasks. A record of the actual hours spent on the transfer project by each member of staff is therefore needed. As there is a fixed budget for the hiring temporary staff a careful record of the actual hours and costs of temporary staff would also be required.
