Cheers for the replies. After further reading I found it apparently can be used to plan individual duties.
However, in the Individual Performances Standards - Delivery Office found at http://www.cwu-e4.co.uk/individual_perf ... idence.pdf
"Below is an example of the process management are using to calculate office throughputs, sorting hours, sorting rates and preparation times for performance and planning purposes.
Mail Vol. / IP Standard = Estimated Sorting Hours
Work Area Hrs * 60 * IP Standard = Estimated Sorting Throughput
Mail Vol. / Work Hrs = Sort Rate
Prep Vol. / No. Walks = Estimated Prep Time
IP Std (For Frame)
We wish to make it clear to representatives that the above process is not agreed with the CWU, and disagreement should be registered immediately and your Divisional rep informed if management adopt this approach to performance and planning."
Is the above different to IWT then?
