Feasibility of pyside2 to be integrated with the current CPD framework (amount of work, architectural impact, amount and design of code, etc.), Whether the same look-and-feel can be achieved using Qt (pyside2) as with the Tcl/Tk, Compare the performance of the Qt-based UI against the original Tcl/Tk with regards to UI build-up, responsiveness, etc. What is the software impact of migrating the UI technology (how many source code need to be touched), Feasibility of using squish to do automatic UI testing once the application is migrated to use Qt (pyside2), The study should take the form of Proof-of-Concept by migrating (at least) one of the CPD application to the new UI technology; When proven feasible, present the amount of work spent, and use this information to estimate impact and amount of work to perform total migration. These should be welly documented with technical details.
