Example text
After you have reduced the list of potential causes to just a few (ideally just one), select one of them as your problem hypothesis. Before you start to test your proposal, however, you have to reassess whether the proposed problem cause is within your area of responsibilities. Figure 2-8 shows the steps that you take to reach a hypothesis followed by escalating it to another group, or by testing your hypothesis. Figure 2-8. Formulating a Hypothesis Is Followed by Escalation or Testing the Hypothesis If you decide to escalate the problem, ask yourself if this ends your involvement in the process.
You must determine whether this problem is your responsibility or if it needs to be escalated to another department or person. For example, assume the reported problem is this: “When user Y tries to access the corporate directory on the company intranet, she gets a message that says permission is denied. ” You are a network engineer, and you do not have access to the servers. A separate department in your company manages the intranet servers. Therefore, you must know what to do when this type of problem is reported to you as a network problem.
It might be clear that this method is most effective if the problem is on one of the higher OSI layers. This approach is also one of the most straightforward troubleshooting methods, because problems reported by users are typically defined as application layer problems, so starting the troubleshooting process at that layer is an obvious thing to do. A drawback or impediment to this method is that you need to have access to the client’s application layer software to initiate the troubleshooting process, and if the software is only installed on a small number of machines, your troubleshooting options might be limited.
