Procedures can be created with two different types of columns that allow users to be responsible for specific tasks. A person column is the simplified way of assigning a user to a row in a group. The role column abstract the users and makes it easy for people with corresponding roles to be responsible for specific tasks.
Users associated with tasks in instances are notified of their responsibilities. Other users associated with running instances have visibility into everyone's responsibility to ensure the procedure is completed on-time and successfully.
