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.
The PPDIOO lifecycle is a valuable tool that can be used in a variety of different situations. As with any process, it does require a certain amount of training to ensure that everyone involved is aware of how the approach works. The cost of this training is, however, minimal compared with the advantages that a company gets from following an optimized process. Take a look through the references for a more detailed explanation of the various phases; there are also a number of different case studies that have been made available by Cisco on their web site.
