Corporate growth is a key for the development of the economy, job creation and the well-being of the society. Previous research (e.g. GEM - Global Entrepreneurship Monitor) shows that Slovenia's corporate potential has a lot of room for improvement. A similar conclusion was reached in the field of timber industry, because many opportunities have been lost. Our research was performed in small timber firms: from total 410 questionnaires 41 were correctly filled. On their basis a SWOT analysis was performed, and proposal of a strategic model of entrepreneurship development in the timber industry prepared. An important tool for achieving this was the corporate plan for which several key points were developed. Our research shows that few entrepreneurs have such a plan and fewer still use it.
