How to Perform Data Quality Assurance

This guide provides a step by step walkthrough of conducting Data Quality Assurance in the Collect Module of the ECO-OS platform.


  1. Identify Missing Data

On the collect dashboard, see the number of missing data entries for each category in orange.

The total missing count for the selected year appears at the top.

A completeness bar and due date marker indicate the progress in each category.


  1. Select a Category

Click on the desired category you want to inspect (e.g. Energy).


  1. Select a Specific Asset

Within the chosen category, select the asset you’d like to inspect (e.g., Facility A).
(Note that some parent assets, such as ABC Company, may not contain any data points)


  1. Select and Expand Data Sub-Category

Click the “+” icon next to the sub-category name to view the data points.


  1. Open Data Point Toolbar

Click the double downward arrow to expand the data point toolbar.


  1. View Chart and Detailed Data

Select the “Chart” icon. This displays the values over a 3-year time period.

Hover over each point to see more details and spot any irregular trends. In this case, the 2025 data is significantly lower than previous years.


  1. Verify Data Accuracy

To ensure that data has been entered correctly, conduct the following actions:

Review monthly data against data source to ensure there are no errors.

Check that the units are entered in their original value. In this example, the last reported data was entered in MMBTU, and the recent data was incorrectly entered in m³.

Select the correct unit from the drop-down menu.

Note: Non-whole numbers must be represented using a decimal point [e.g. 100.55] and not using a comma [100,55]


  1. Save Changes

Click the blinking yellow disc icon to save your changes.


  1. Refresh the Chart to View Updated Data

Click on the “Chart” icon or refresh the internet browser to see the chart updated with the new data.
