We examine a mechanism for internal corporate planning that accounts for changes in the external environment. Factors influencing the external environment are described in terms of capital, labor, and materials. The relationship between external factors and indicators and their impact on the company’s internal environment is examined. Based on these relationships, an optimal operating strategy is developed. The model is illustrated using the example of a manufacturing company. To obtain initial industry data, financial statements from approximately 2 million Russian organizations were processed. From this dataset, information on industry development was extracted using big data processing.
