  • 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. © 2006 Cisco Systems, Inc.
