In the DevOps philosophy, one critical item to focus on is the co-relation of a software delivery functions that need to be performed to the tools that are being used. Tools are nothing but a constrained codification of a process so the actual tooling is always secondary to the function that needs to be satisfied. So as long as a function is satisfied when it comes to delivery (like code analysis or monitoring); what tool you use or do not, really does not matter.
One very precise way to look and think about DevOps is using this Service Delivery quadrant. For all enterprises that think about DevOps, a key question to ask – are all of these functions full filled at all steps of delivery?
The tools can substitute each of the functions above in blue but make sure, the function is given importance and is being full-filled with the tools being optional or secondary.
