To me DevOps is a cost cutting measure whereby an organization can save a few hundred thousand dollars by having one individual not only do the development but also handle the deployment and the testing.

In theory that will eliminate the need for an additional tester and a second individual to do the change control.

But those short term gains expose the organization to the massive risks that the one and only one individual will make a mistake, with no second individual available to do a double check.

The reality is people make mistakes and by eliminating people from that double checking process may well save money in the short term, but in the long run it greatly adds to the of risk failure.

While there are short term gains, the risks to the organization can be massive:
