The application teams on the right focuses on business functionality, viewing the network as a dependable system that they just need a socket to plug into. Once complete, the application is “thrown over the wall” to the network staff, often with little prep or communication. On the network side, the application package comes over the wall only to discover a myriad of issues unfold as it’s unwrapped and deployed in the real world. The real challenge is that networks aren’t adaptable enough to handle the application level challenges that often drop in their lap. And when the application surprise is discovered the IT fire alarm sounds organizations as organizations wrestle with out to best solve the issue.
