In today's world, there is an increasing number of individuals who aspire to start their own business. In order to successfully achieve this, it is necessary to have a good business idea and a business plan. A business plan is a document that outlines the goals, strategies, and operational guidelines for conducting a business venture. It is a crucial tool for planning, organizing, and managing business activities, serving as the foundation for successful operations. A business plan helps entrepreneurs clearly define their objectives, identify target markets, analyze the industry and competition, develop marketing strategies, plan financial resources, and assess potential risks and challenges. The business plan consists of eight chapters: executive summary, description of the entrepreneurial idea, market and industry analysis, technological determinants of the project, management, marketing, financial data, and performance evaluation.
