Further, there is a monetary cost associated with finding and fixing bugs in your software and
infrastructure code, and that cost goes up the further out in the development cycle you dis-
cover issues.
Figure 16-3
shows the relative cost of fixing a software bug as development
progresses. Your infrastructure code is no different than application code in this respect:
▪ Requirements
▪ Design
▪ Coding
▪ Development testing
▪ Acceptance testing
▪ Operations/production
