SummaryStandardized methods for data collection and reporting and minimize collection biases. This approach is more likely to facilitate data and knowledge sharing, which is critical to manage complex human activities in response to similarly-complex natural systems. General Information about this IndicatorWhat is it?: A common problem in synthesizing data to measure performance of complex systems is the lack of data format and data collection standardization among entities, even for common metrics. There is a similar lack in data sharing, sometimes within entities. A large agency, group of agencies, or more diverse partnership is more likely to understand, predict changes, and be able to sustain complex systems if basic data standardization and sharing protocols are developed and followed.
