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.
