This article describes the process of strategy formulation and implementation as observed in entrepreneurial new ventures formed in the Republic of Ireland. It analyses these processes, and especially the strategy implementation processes, in the context of some traditional themes of research on new venture management and strategic management. Special attention is paid to the relationships between the entrepreneur and organisational stages of development, on the one hand, and strategy implementation, on the other. In addition, the impact of the type of entry strategy adopted on the implementation process is explored, as too is the manner in which learning takes place through strategy implementation. Finally, some implications of the findings for popular concepts of strategy formulation and implementation are outlined and discussed.
