A
As-Built Section (ABS)
(Context: Enterprise Architecture, General, Technology Management)
VITA EA: Architecture Overview Document (AOD) is split into 3 sections to be completed at different times in the lifecycle of service deployment. Each architecture will include a High-Level Section (HLS), Detailed Design Section (DDS), and an As Built Section (ABS). As-Built Section (ABS) - Contains any variances from the Detailed Design Section (DDS) and their configurations. It needs to be completed prior to project closeout. Ideally this section is just a check off of the approved design, but sometimes there is a reason to vary from it. The purpose of this section is to capture variations from the approved architecture and designs so that if there is a need to rebuild this system from scratch, we have the knowledge.
General: A description of the state of an IT system as implemented. Where a Design Document provides the technical specification of a system to be constructed, an As-Built Document outlines the deployed system in detail, including hardware specifications, serial numbers, MAC & WWN addresses, host and domain names, software versions, patch levels, configuration settings, and system resources. It is not a Runbook, which is a procedural guide for how to install and configure a system, and to maintain it at runtime.
