摘要:Highly intensive internalization of the world economy requires the business sector to have different view of strategic management and decision making, together with the quality and content of business processes. Changes in the environment of enterprises significantly influence their function and behaviour, causing a need to significantly change enterprise architecture, including the design of development strategies. The paper focuses on analysing the processes of industrial enterprises, dealing with their importance and profit, classified by size. The result revealed that process activities, such as input logistics and marketing, are dominant in micro-enterprises, and such activities are important in profitable enterprises. In middle-sized enterprises, there is a more significant difference between marketing/sales and services without any relations to profit. However, there is a requirement to intensify these activities in non-profitable enterprises. Large enterprises revealed a significant influence of the scientific and technological development and also, to a lesser extent, of marketing, sales and purchase. Non-profitable enterprises should also focus on improving the quality of such processes.
