Optimize Phases
Key
To p i c
Cisco has formalized a network's life cycle into six phases: Prepare, Plan, Design,
Implement, Operate, and Optimize. These phases are collectively known as PPDIOO.
The PPDIOO life cycle provides four main benefits:
It lowers the total cost of ownership by validating technology requirements and plan-
ning for infrastructure changes and resource requirements.
■
It increases network availability by producing a sound network design and validating
the network operation.
■
It improves business agility by establishing business requirements and technology
strategies.
■
It speeds access to applications and services by improving availability, reliability, se-
curity, scalability, and performance.
