The Secret to Effective Network Management

Like a lot of you, I've made a career out of getting supposedly easy-to-use technology to work. But breaking my head over a router misconfiguration or a VPN that won't connect isn't what bothers me. What bothers me are the engineers who just don't get what really matters about our work: helping users solve their business problems.

Whether we're talking about external customers who directly pay our salary or internal customers who indirectly pay our salary, customers don't hire us to implement VPNs or light up fiber or install VoIP systems. Customers pay us to solve problems. They couldn't care less if we pinged stuff all day long. At the end of the day, all they want to know is, does the application work? We do them a gross disservice when we walk away with things working from our perspective, without first checking to see if things work from their perspective. Yet I see this happen all the time.


A couple of years ago, I received a call to troubleshoot a critical health care application at one of our customer's sites. Apparently, this application failed to work properly after the underlying frame relay network was replaced with an Internet-based VPN. I planned to go onsite to fix the problem, but when the engineer of record heard this, he became irate. "It pings fine," he insisted, not quite using colorful language, but obviously upset that his professional acumen was being called into question. He just couldn't get over why I would even bother going to the site. After all, the site answered to a ping, so in his opinion clearly all was well.

Upon arriving at the site, I could see the problem. The VPN was up so ping did work, but the host-level configuration hadn't been completed. In other words, the operation--changing over to a cheaper transport--was a success, but the patient--our application--died.
