Like any significant change to a service provider's operational support system (OSS), technology migration can be a significant challenge. Success requires in-depth understanding and systematic planning.
To help you meet your business objectives, the IP NGN Expertise Center follows a methodology for structured program delivery based on the PPDIOO model: prepare, plan, design, implement, operate, and optimize:
The approach is based on Cisco research and development efforts, as well as knowledge gathered from successful solution engagements.
Cisco promotes it across its service-delivery organization as well as its partner ecosystem, and supports it through Web-based delivery.
Because it has standardize on a common approach, Cisco can assemble project teams with members from different geographic areas and with different areas of expertise, and ensure they collaborate effectively.
Benefits include faster time to market, reduced cost, and high quality service delivery.
By using the structured PPDIOO process and IP NGN Program Central, a Web-based management system, Cisco effectively manages highly distributed workforces and systems to provide you with the best return on your investment.

Site Requirements Specifications (SRS)
Solutions Test Plan (STP)
Site Survey Form (SSF)
Customer Requirements Document Response (CRDR)
During the Plan phase, Cisco refines the preliminary strategy developed during the Prepare phase to establish high-level requirements and functionality needed for use test and validation testing-but not yet for specific tests. To add detail, Cisco verifies the customer requirements document, conducts planning workshops, and administers more detailed surveys. Verification of the customer requirements document is recorded with a formal CRD Response Document (CRDR). Depending on the details of the engagement, other deliverable might include a Site Requirements Specifications (SRS), or a Fault Management Test Plan (FMTP). The final deliverable of this phase, a high-level STP, documents the testing teams and their responsibilities, testing tasks, types of tests, and a schedule or process for test execution. It provides the detail that supporting staff need to properly schedule and staff for testing.
