What we LearntWhat we Learnt

Requirement for “shakeout” period• Integration “not easy”• Real user testing required, not just automated tools

GUIs with C++ not quick fixes - maybe Java would have been easier??

CORBA Servers need to be VERY robust in a high use environment

Customers are usually BIG organisations, which affects the turnaround time for problems

Future WorkFuture Work

Additional user functionality• CSV export• Enhanced sorting and filtering

Web based reporting for CSRs• how many customers accessing certain• usage of functions

Improve ability to change GUI characteristics quickly• for enhancement• for new clients!
