Examples

Always create the simplest project configuration possible. If you are not sure that your project requires a feature, do not enable the feature as most features can be enabled later. Once a feature is enabled and data is entered, it may not be able to be disabled. However, Randomization and Screening cannot be enabled once subjects are enrolled in the project.
