Due to internal and external requirements, business processes in all organizational systems are subject to changes and necessary improvements. In particular, it applies to organisational and business systems that are in the early stages of their growth and development. The subject of this paper is an analysis of business processes with the aim of detecting bottlenecks and shortcomings of business processes and proposals for their improvement. The immediate aim of the paper was to conduct an analysis of business processes in a relatively young manufacturing company to conduct an analysis of key business macroprocesses (supply chain and logistics), to determine their strengths and weaknesses and to propose improvements based on selected internal and external criteria. The analysis process was carried out using two groups of process diagrams: EPC diagram and BPMN diagram. EPC notation represents an event-driven process chain, while BPMN denotes a graphical representation for determining business processes in a business process model. The diagrams were used to describe the existing processes with the aim of identifying defects, after which improvements were proposed and improved processes were re-presented. The paper is divided into six chapters, starting with basic theoretical assumptions for managing business processes. Then, business analysis and its purpose, as well as performance and optimization of business processes, are described. After that, processes in supply chains, logistics and distribution were defined. The influence of the supply chain for the company was highlighted because proper management improves its operations. Furthermore, the business of Nutris ™, founded in 2019, which offers a food, innovative and sustainable concept with an emphasis on plant production, using the principles of the circular economy, is described. It includes NUTRIS.farm ™, NUTRIS. tech ™ and NUTRIS.me ™ branches where “farm” is a branch responsible for finding subcontractors and raw materials, and “tech” is a branch responsible for the product business process. Furthermore, the sources of distribution channels and the long-term strategy selected by Nutris ™ in view of the foreseeable strategic future as well as geographical location are presented in theory. After that, using EPC and BPMN notations, the company's business process was analysed. The explanation of the current process uses the “as-is” method, while the “to be” method is used in the improved process. Finally, it emphasises the importanceof self-sustainability and finding alternative sources of plant-based food, as well as reducing the consumption of animal proteins while increasing the production of plant-based protein worldwide. It also stressed the importance of reducing the negative impact on the environment, as well as the importance of preserving the environment for future generations.
