Factors contributing to business recovery 6–8 months after Hurricane Katrina were examined. Managers from 183 surviving organizations in the Greater New Orleans area rated the levels of storm preparation, amount of storm damage, severity of storm-related problems and organizational performance. Factors under management's control such as having an emergency response plan, storm preparation and effective staff communication had no real impact on organizational performance. Significant predictors with a negative impact on organizational performance included variables such as storm damage and post-disaster problems. Complications arising from extreme population dislocation, specifically loss of customer base and staffing issues, had the greatest impact on organizational performance. The implications for disaster preparation and management are discussed.
