Cisco Lifecycle Services
Cisco Lifecycle Services is designed to support evolving networks. Cisco Lifecycle Services is a six-phase approach to deploying and operating Cisco technologies.

The six phases of the Cisco Lifecycle Services are:
• The Preparation Phase
• The Plan Phase
• The Design Phase
• The Implement Phase
• The Operate Phase -maintenance
• The Optimize Phase -maintenance

• In the Prepare phase, the business goals of the project are identified and a business case is created to justify the installation of the network upgrade.
• During the Plan phase, the network designer performs a comprehensive site and operations assessment of the current network. A project plan is created that includes the tasks, time-lines, risks, responsibilities and the resources required to complete the network design project.
• In the Design Phase, the designer creates a flexible design that can integrate new technologies into the current operations and existing network infrastructure.
• During the Implement phase, the network is built according to the approved designs and specifications and tested to ensure it meets the business goals and requirements.
• The Operate and Optimize phases of the network lifecycle are ongoing and represent the day-to-day operations of the network. Optimizing a network is a continuous process that identifies and resolves potential weaknesses before they become problems for network operations.

The proposal typically contains the following sections:

A. Executive Summary
B. Network Requirements (planning stage)
C. Current Network Environment (planning stage)
D. Proposed Physical Design
E. Proposed Logical Design
F. Implementation Plan
G. Cost Estimate
