Two Systems?
? would need two systems for distribution of data.
1. Using Excel to chart TATs for Monthly QA meetings. Tables containing daily and weekly TATs are generated and then graphs built from these tables.
2. Web display of data could do as above but on the fly. However as data is unlikely to change on a regular basis (monthly) then tables could be generated as per 1. New data could trigger generation of new tables of statistical data.
