The paper discusses risk management and analysis of a small enterprise. A particular enterprise-oriented analysis approach is developed and performed using such research methods as descriptive modeling, business process modeling, ABC analysis, risk identification and classification, qualitative and quantitative risk analysis. The customer service level is used as a performance indicator of quality. The paper introduces the statistical approach to the analysis of the dependence of quality from an inventory management strategy under uncertainty of demand in different scenarios. The analysis of simulation results shows how a certain approach can be applied to reveal sensitive spots and gaps in the business process.
