Which problem-solving process is commonly used when addressing bugs in software?

• A. Define the problem, brainstorm hypotheses, test, implement fix, and verify
• B. Randomly adjust settings
• C. Ignore the issue
• D. Reboot only

Answer: (A)

Addressing bugs in software is best done with a structured, evidence-driven debugging process. This approach starts by clearly defining the problem and the observed symptoms to avoid chasing irrelevant details. Developers then form hypotheses about possible causes based on data, logs, and recent changes. They test these hypotheses with controlled checks or experiments, such as reproducing the bug, adding or running targeted tests, and instrumenting the code to gather more information. Based on what’s learned, they implement a fix that targets the root cause and then verify the result by re-running tests, performing regression checks, and monitoring to ensure the issue is resolved without introducing new problems. This cycle provides confidence that the bug is truly fixed and won't reappear. The other options don’t fit because they are unsystematic or merely masking the problem: randomly changing settings is guesswork, ignoring the issue leaves it unresolved, and rebooting only hides symptoms without diagnosing or validating a fix.
