I'm working on trying to teach others in my group (usually less-experienced, but not always) how to improve their large-network troubleshooting skills (the techniques of isolating a problem, etc).
It's been so long since I learned network troubleshooting techniques I can't remember how I learned them or even how I used to do it (so poorly). Does anyone have experience with developing a skills-improvement program on this topic? If you've tried such a thing, what worked/didn't work for you? Outside training? Books? Mentoring? Motivational posters? I'm particularly sensitive to the "I got my CCNA, therefore I know everything there is to know about troubleshooting" perspective, and how to encourage improving troubleshooting skills without making it insultingly basic. Thanks for your help. Pete.
