The spread of COVID-19 has disrupted firm operations on a global scale. Using a comprehensive data set that observes over 3,000 firms in 16 countries, including several developing countries, shortly before and after the pandemic, we relate firms' structured management practices to post- COIVD-19 outcomes, and report four main findings. First, structured management practices are associated with more limited downside impacts of the crisis on firm sales and survival in manufacturing but not in services. Better managed manufacturing firms, on average, experience a smaller reduction in sales. Second, in both manufacturing and services, structured management practice scores are correlated with a firm's ability to adjust or convert product mix and shift to online work arrangements. Third, management scores are not correlated with firm's ability to adjust on employment margins. Fourth, the resilience of better managed firms is related primarily to incentive practices and is uncorrelated with operations or targeting practices. Monitoring practice scores show a modest correlation with a firm's ability to switch to remote work arrangements.
