Issues experienced during user acceptance testing may delay implementation of the new Personal Properties Securities Register beyond October 31, the Attorney-General's Department confirmed on Friday.On Friday afternoon, the department advised stakeholders, via email, of a need for "further internal testing" of "the issues recently experienced during the user acceptance testing of the PPSR."As reported by Banking Day last Monday, department officials told a seminar two Fridays ago that the register could not go live if the software wasn't properly tested or the industry wasn't ready.According to Friday's advisory: "This delay in successfully completing user acceptance testing has clearly put pressure on the schedule for delivery on 31 October 2011.  "Until we are certain that the system issues have been resolved we are not able to fully assess the impact" on the planned commencement date for the register in two months time.The Attorney-General, Robert McClelland, has until the first week of September to certify the system is ready to implement, assuming his department and key stakeholders regard the present timetable as viable. However, a decision to defer implementation seems likely, based on the flow of cautionary advice from departmental officials over the last two weeks.
