Adding metrics is an important step in creating a good Project. Metrics have their own tab in Projects. Navigate there to manage your Project's Metrics:
- To add a new metric from your organization's already-created metrics, use the search bar to find the metric by name. When you see it in the search results, click on it, and you will be able to configure the metric specifically for this Project.
- Click the blue 'Create New Metric' button to create an additional metric for your entire organization. Be sure to check for a duplicate by using the search box before adding a new metric.
Note that if you choose your Metric Format as a Percentage, you should enter your metric's value as a decimal (.5 would be 50%).
