# Step 2: Collect and Maintain Data
Establish practices for maintaining data quality and collect data from fact sheet owners.
After importing an initial set of fact sheets into your workspace, the next step is to implement data quality practices and collect additional data from application owners. This lets you ensure the completeness and accuracy of your inventory data.
Follow these steps:
  1. [Identify and assign fact sheet owners](https://help.sap.com/docs/leanix/ea/assign-fact-sheet-owners?locale=en-US&state=PRODUCTION&version=CLOUD "After importing initial data into your workspace, identify and assign application owners to define responsibility for maintaining fact sheet data."): Define application owners to assign responsibility and accountability for maintaining fact sheet data. Add application owners to fact sheets as subscribers.
