The document discusses the four stages of environmental analysis: scanning, monitoring, forecasting, and assessment. Environmental scanning involves ongoing tracking of internal and external trends and occurrences that could impact an organization's success. Monitoring involves deeper analysis of relevant environmental forces identified through scanning using techniques like reviewing company records. Forecasting estimates future events based on past and present analysis using techniques like time series analysis. Environmental factors are assessed for their impact on the organization as opportunities or threats using techniques like SWOT analysis.
