Answer:
Step 1: identify the problem
In this step we need identify what is the actual problem that is occurring and where the problem is occurring. Information is gathered, problem symptoms are analyzed to identify the underlying issue.
Step 2: Establish a theory of probable cause.
In this step all the possible causes of the problem are compiled in a list.
This list of possible causes should then be divided into three ranked sections.
Step 3: Test the theory to determine cause.
In this step, we use the the list of potential causes obtained in the above test to test the theory for that particular cause. If proved/confirmed, then we should move to the next step otherwise( in case proved incorrect) the established theory of probable causes needs to be remade/re-established.
Step 4: Establish a plan of action to resolve the problem and identify potential effects.
In this step a plan of action is established and potential effects of the same are identified. For example a particular course of action can have critical/serious repercussion, so all the effects of executing a particular plan must be identified.
Step 5: Implement the plan/solution or escalate as necessary.
The established plan must be implemented if sufficient authority otherwise it should be escalated to the higher authority along with all the documents, findings and plans to account for efficient and fast resolution.
Step 6: Verify full system functionality.
Once solution implemented, check if the original problem is resolved. Apart from original problem check if no other problem is induced in the system due to the steps/plan taken to solve the original problem. So verify full system functionality/operation.
Step 7: Document findings, actions, and outcomes.
