CCDA Study: What is PPDIOO?

Studying for CCDA: What is PPDIOO?

I’ve been studying for the Cisco Certified Design Associate (CCDA) to give me a better insight and view of the Cisco design methodology. I’m trying to be well rounded overall and this is one of weaker areas. It’s been interesting and I’m learning a lot in the way of how Cisco sees the building blocks for a network design.

I came across the acronym PPDIOO which stands for Prepare, Plan, Design, Implement, Operate, and Optimize.

This is the network lifecyle. Each phase builds up to the next phase and provides a roadmap of how a network should be implemented, designed and upgraded.

PPDIOO Phase Description
Prepare Establishes organizational and business requirements, develops a network strategy, and proposes a high-level architecture
Plan Identifies the network requirements by characterizing and assessing the network, performing a gap analysis
Design Provides high availability, reliability, security, scalability, and performance
Implement Installation and configuration of new equipment
Operate Day-to-day network operations
Optimize Proactive network management; modifications to the design

These different phases sound very familiar and match up to other design frameworks, ontologies or methodologies. But they all have a central focus on logically breaking down each step to provide a repeatable process in which all points are thought out.
