In this course, you will learn how to quickly identify problems, establish a cause, test theories, determine a plan of action, and recognize potential effects of the treatment. Begin by finding out how to implement an appropriate solution or escalate it, if required. Next, verify that things work after the solution. This involves documenting findings, actions, and outcomes.
