Lessons from great leaders, Lovell, Kranz and Liebergot #failureisnotanoption

Image
"Failure is not an option" and "Houston, we have a problem" are phrases from the movie Apollo 13 (one of my greatest movies ever, review it here). Lovell, Kranz and Liebergot have a close association to the Apollo programme, especially Apollo 13, and these great leaders are central to the story of "Failure is not an option."

It's not about the uptime - time to throw away the RAGs

Image
All network management products miss the point. Their primary focus is on monitoring uptime. This is often referred to as a RAG tool. Red, Amber, Green where Red signifies down,Amber signifies intermittent connectivity problems and Green signifies good connectivity. This serves no business purpose and cannot justify any return on investment. All the development is in looking at when the situation is acceptable but none when you are in dire straits. How is this monitoring? All it does is give you a comfortable feeling. With this approach there is no difference in the value proposition of 'ping' or a network management framework product worth a million bucks. What is required is to monitor downtime. Outages require a special view that is serialized and has the outage time.

The expanded incident life cycle is not enforced and as a result trending and problem management is not possible. Read the article over at LinkedIn: Flawed "ITIL aligned"​ Incident Management

Why Madge Networks, the token-ring company, went titsup

Image
There I was shooting the breeze with an old mate. The conversation turned to why Madge Networks which I wrote about here went titsup. My analysis is that Madge Networks had a solution and decided to go out and find a problem. They deferred to more incorrect strategic technology choices. The truth of the matter is that when something goes titsup, its not because of one reason only, but a myriad of them all contributing to the negative consequence. There are the immediate or visual ones, which are underpinned by intermediate ones and finally after digging right down, there are the root causes. There is never a singular root cause for anything but I'll present my opinion and encourage everyone else to chip in. All of them together are more likely the reason the company went titsup.
