Chapter 6
Designing and Staging Projects
Simple changes--such as opening a new port in a firewall--are fairly simple. Although they still
need to go through a complete peer review and risk analysis, those steps can go by quickly for
such a straightforward change, and you don't generally need a dedicated tool to help you design
and plan the change.
More complex projects, such as deploying a new router or changing your network's IP
addressing scheme, definitely require design and planning. Although these steps can be easily
performed without the benefit of tools (indeed, most administrators probably design their
changes manually), tools with the right features can offer significant benefits.
Contribution to the Configuration Management Process
One benefit I've discussed at length in previous chapters is the use of templates to develop
changes. Another is the ability for a configuration management tool to enforce a workflow for
peer review and approval of changes. Both are critical to a valid configuration management
process; the steps highlighted in Figure 6.1 (shaded in yellow) show how this contribution might
fit into a typical configuration management process.
