This study reports on the results of a nationwide survey of public procurement in Ireland, carried out against a backdrop of central government reform initiatives. The survey was designed to address a knowledge deficit among academics, policy makers and practitioners on the form and functioning of public procurement in Ireland. Thus, a mapping of public procurement was undertaken in 2011 in conjunction with the National Procurement Service (NPS) of Ireland. The population of suppliers and public sector procurers registered on Ireland’s national e-procurement portal was requested to participate in this exercise by completing an online questionnaire. This yielded an extensive dataset relevant to understanding the Irish public procurement market. That data was obtained from both suppliers and public sector procurers allows for comparisons to be made across a range of variables, which is a novel addition to research in the public procurement field. The significance of the research and its findings go beyond Ireland. Contemporary issues of international concern, such as the marketplace impacts of migration to e-procurement, initiatives to create a “level playing field” for small and medium-sized (SMEs) enterprises, and the effects of European Union directives, are analysed and their importance discussed. In the next section the policy environment as it pertains to public procurement in Ireland is described. The design of the research is explained in section three and the survey findings are detailed in section four. These findings are subject to further examination and contextualisation in section five.
