Information systems have the capacity to support all levels of decision making within an organization from operational through tactical (managerial) to strategic decision-making. It is the additional capacity to provide a competitive edge that has driven many organisations to make heavy investments both in information systems and the information technology to run them on. It was this realisation that drove Parliament of Zimbabwe (PoZ) to develop an information system that addressed the needs of the users, Members of Parliament and Civil Society Organisations.
