Although there is general agreement about the importance of assessing publicly supported entrepreneurship programmes, the design and implementation of reliable evaluations of such public interventions deserve further theoretical and empirical attention (Audretsch, Grilo and Thurik, 2007), especially in the case of those directed at early stage innovative ventures (Norrman and Bager-Sjogren, 2010). Moreover, although studies of new venture creation have shown that no single pattern of events is common to all new ventures (Carter, Gartner and Reynolds, 1996) our understanding of the venturing process remains highly fragmented (Moroz and Hindle, 2012). Therefore some scholars have argued that we have prematurely measured the impact of entrepreneurship policy initiatives without a good understanding of the actual venturing processes. In this paper we investigate how the design, implementation and evaluation of public initiatives that aim to improve entrepreneurial activity interact with the venturing processes in a specific system.
