In the modern world of computer networks there are many moving parts that must be carefully controlled in order to get the most out of it. One of the methods that can be used to provide this is by following a network lifecycle; these lifecycles define an approach that can be followed for each stage of the network’s life (Thus lifecycle). Cisco’s version of this is the PPDIOO lifecycle or Prepare, Plan, Design, Implement, Operate and Optimize. This article gives an overview of the PPDIOO lifecycle, what happens at each stage, and what potential deliverables would be expected at each stage.
