The DQO Process is a seven-step planning approach based on the scientific method that is used to prepare for data collection activities such as environmental monitoring efforts and research. It provides the criteria that a data collection design should satisfy, including when, where, and how to collect samples; tolerable decision error rates; and the number of samples to collect.

The DQO Process is a strategic planning approach based on the Scientific Method to prepare for a data collection activity. DQOs provide a systematic procedure for defining the criteria that a data collection design should satisfy, including when to collect samples, where to collect samples, the tolerable level of decision error for a study, and how many samples to collect, balancing risk and cost in an acceptable manner.
