My principles in problem-solving

• 50+% is done when understanding the problem well.
• Every problem-solving SHOULD be a one-way journey.

Application to troubleshooting

• 50+% is done when understanding the trouble well.
• Every troubleshooting SHOULD be a one-way journey to identify what to be corrected.
