Deployment of the network must start with a plan and a schedule. Deployment planning starts in the PDIOO Design phase and continues into the Implement phase.
The deployment plan must include details of what is to be done and how it is to be done. For example, if new cabling is required, the procedure to run the cable and the location where it is needed must be fully documented. Scheduling is important, not only to identify when things will be done but also to determine who will do them, and what impact the deployment will have on the existing network. For example, if current applications must still work while the new network is being implemented, the schedule must show any times during which the applications will be unavailable.
Contingency plans, that is, plans for what happens if a problem occurs during the implementation, should also be included. These contingency plans should address how the network will be returned to a known working state, if possible. Testing should be incorporated into the deployment plan to ensure that the functions are working as they are implemented.
Any training required for personnel should be planned during this time. For example, if you are deploying a Voice over IP (VoIP) solution, the network administrators might require some instruction on the technology before they can implement and maintain it.
Any contracts required should be negotiated during this time. Examples include outsourcing, Internet connectivity, maintenance, and so forth.
When the plans, schedules, contracts, and so on are in place, the network can be implemented. Any problems found in the design during this phase must be corrected and documented.
