The Resource Ranking area allows you to grade / rank each of your resources to help when choosing the right resource for a job. Once you set up a ranking, these can be updated for each contractor on the Resource Details page. This will aid in your decision to assign the most appropriate contractor to a particular job.
You can add a resource ranking by selecting the Add Grade/Ranking button at the top-left of the page:
This will create a new row where you can name the Grade / Ranking and assign a Priority. Once you have finished inputting the data, select Update in order to save the new Grade/Ranking and add it to the list.
You can also Edit / Delete the Grade / Ranking information once it has been added to the list.
