Summary

 The six phases of the network lifecycle include prepare,

plan, design, implement, operate, and optimize.

 A project plan includes tasks, timelines, risks,

responsibilities, and resources required to complete a network design project.

 Following the required format and schedule is critical to

submitting a successful proposal.

 All members of the networking contractor staff must

demonstrate effective interpersonal skills.

 Top-down network design strategies have the best

chance to succeed.

 A primary requirement for any network is the availability
