26. 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
of qualified support personnel.
