Errors do occur. They occur for a reason. Often those reasons are out of our control. Someone changes an IP Address of a server. Someone changes the password to the back office system. Someone changes the name of a shared .DLL.
Of course in a well-managed and carefully controlled environment those kinds of things shouldn’t happen without the proper authentication, notification and approval. And the infamous “someone” is a responsible professional who calculates the impact of their changes and collaborates with everyone to minimize that impact. In a perfect world.
In the real world change is constant and calculating the consequences of change
Helicopters have been described as “10,000 parts flying together in close formation. It is the mechanic’s job to keep that formation as tight as possible.”
Modern software applications comprise of millions of parts when you consider the huge chunks of code we bind into our applications from the database, security, web server, communications, encryption and authentication vendors. Add to that the seemingly infinite numbers of dependencies on external web services and internal CRM and financial systems.There are 100 million lines of code in the Ford Taurus
But, just like the helicopter’s mechanic, the
“I don’t want to know why it happened: I just want you to fix it!” was what I was told early one morning by the Director of Sales. And she was right: getting the online store back online was the most important thing for the business. Blamestorming would come later.
There is a temptation at 3:00 am to just do whatever it takes to bring the system back on the air even if that means bypassing protocols and procedures designed to protect system integrity. Sales-and-Marketing and Audit-and-Compliance might not see eye-to-eye on this approach.

In the last post we talked about some of the myths about release and deployment. Perhaps the most telling comment there was the belief that “Every deployment is unique.”
Let’s break that apart and see what it really means and why it just doesn’t hold up in reality.
Deploying an application comprises of a number of parts:
It has been pretty hectic here this afternoon at the Serena booth (#418) where we are showcasing the latest version of ChangeMan SSM to the nearly 1,000 attendees.

In this 7-part series we’ll look at some common misconceptions about the process of deploying software in today’s unforgiving world. Over the next few posts we tackle these myths head on and show how there is a better way.
Releasing software into the wild is exciting and terrifying. When it goes well: we party. When it doesn’t: we spend the weekend without sleep, showers, food or sleep. Wait! Did I mention no sleep already?
Too often the reason our deployments fail is because we fall into the same traps
