Establish a Theory of Probable Cause
After identifying the problem, the next step is to establish a theory of probable cause. This step involves using your technical knowledge, experience, and analytical skills to determine the most likely causes of the issue based on the information gathered during the problem identification stage. You may need to do research, consult documentation, or engage in discussion with colleagues to develop your theory. It's crucial to prioritize these potential causes to help guide your troubleshooting and save time and effort. Keep in mind, you may need to revise your theory as new information emerges during the troubleshooting process.
Guide on Establish a Theory of Probable Cause in CompTIA A+ Basic Troubleshooting Techniques
The 'Establish a Theory of Probable Cause' step in troubleshooting refers to the process of determining the most likely reason for a particular problem based on available evidence and knowledge.
Importance: It is essentially the key first step in resolving a technical issue. By correctly establishing a theory of probable cause, you can identify the root cause of an issue quickly and accurately, which greatly aids in solving the problem and prevents future occurrences.
How It Works: This process typically involves gathering data about the problem, analyzing it, and then using your technical knowledge to form a theory. This theory should be testable, meaning you can perform actions to confirm if the theory is correct or not.
Exam Tips: When answering questions about this topic in an exam, always remember to focus on the logical process of determining a problem's cause. Think about the steps involved, how you would use your gathered data to form your theory, and how you would then test your theory. Use specific examples if possible, and remember that there's often more than one possible cause for a problem, so your theory should consider all likely possibilities.
