The aim of this paper is to explore the creation and importance of marketing strategies in engineering companies. At the very beginning of the paper, marketing will be defined, and its significance will be explained through the history of marketing and sales, from its inception to today's digital marketing. Furthermore, the paper will address the topics of engineering companies, their importance, and their classification. By synthesizing the previous chapters, the process of creating a marketing plan will be defined, which includes marketing analysis, marketing environment, and other elements with the goal of gaining a deeper understanding of the creation of marketing strategies and their application in engineering companies. Examples in the paper will demonstrate how engineering companies, that is, companies engaged in the development and production of technological products or services, can successfully create marketing strategies for better and more stable long-term operations. By combining high-quality marketing strategies with stable engineering operations, we arrive at an interdisciplinary field that will be explored in this paper using methods of analysis, synthesis, induction and deduction, and others.
