Waterfall Methodology: Analysis and Design Process

PURPOSESCOPEPROCESS DESCRIPTIONPROCESS INPUTS/OUTPUTSSUPPORTING DOCUMENTATIONREVISION HISTORY

Process Owner: Manager, Business Relationship Management

Note: An owner must be a PCES-level manager.

This document establishes standard processes for the Technology Solution Life Cycle (TSLC) Waterfall Analysis and Design phase within the Postal Service Technical Environment.

PURPOSE

The Analysis and Design process translates the Technology Solution Requirements into an implementable design and finalizes the project’s implementation schedule and costs. Technology components are identified and architected to provide a framework in support of the Technology Solution Build phase.

The objectives of the Analysis and Design process are:

SCOPE

This process applies to all:

PROCESS DESCRIPTION

The Technology Solution Analysis and Design process creates a documented design from approved technology solution requirements.

This process is composed of the following subprocesses:

  1. Follow the Certification and Accreditation Process.
  2. The Business Relationship Management Program Manager (BRM PM) coordinates this task.

    For security-related processes and artifacts, follow the Certification and Accreditation Process as described in the Handbook AS-805A, Information Resource Certification and Accreditation Process.

  3. PCI In-Scope Only: Develop and Maintain Secure PCI In-Scope Systems and Applications.
  4. The BRM PM coordinates this task.

    Ensure that all requirements listed and referenced in the Develop and Maintain Secure PCI In-Scope Systems and Applications are met.

  5. Update Technology Solution Design Documents.
  6. The Technology Solution Coordinator (TSC) coordinates this task.

    Host designs, database designs, network designs, application designs, etc., are updated as appropriate based on the approved requirements document. Host designs may use the provided TSLC template. All technology solution designs will encompass those environments that have been defined within the scope of the technology solution requirements.

  7. Design Walkthrough with All Appropriate Technology Service Providers.
  8. The BRM PM coordinates this task.

    All TSPs who have a stake in the technology solution will bring their draft designs to a walkthrough session. The designs will be reviewed against the requirements. The objective of the walkthrough is for all IT Service Providers to agree on the design. Any changes to requirements as a result of the design must go through the Change Control Board (CCB). 

  9. Review the Impact Assessment(s).
  10. The BRM PM reviews the SOX Impact Assessment (SIA) and/or PCI Impact Assessment (PCI-IA) to determine whether changes that have been made impact the assessment. If changes do impact the assessment, update and resubmit the Impact Assessment(s). If the Impact Assessment(s) are updated, they must be submitted to the respective CCB (SIA to SOX CCB and PCI-IA to PCI CCB) at least 30 days prior to implementation. Changes with a planned implementation date within the high-risk period must be submitted at least 45 days prior to the implementation date.

  11. Update the Project Plan.
  12. The BRM PM coordinates this task.

    The project plan is updated with the information from the milestone information from the TSPs. At this point, the project plan has all the tasks to commit and implement the technology solution.

  13. Perform EA Checkpoint 2.
  14. The BRM PM coordinates this task.

    If Checkpoint 1 was performed, submit the final design, with updates from EA Checkpoint 1, to the Enterprise Architecture Committee for approval. Approval must be obtained by the Enterprise Architecture Committee for all projects introducing new or expanded use of IT services, technology solutions, or COTS software. This review process also applies to projects that require upgrades to software previously approved for inclusion.

  15. Tollgate Process Only: Conduct Finalize Release Tollgate.
  16. If the release has been selected for the Tollgate process, the third Tollgate meeting will take place at the end of the Design phase.

    The following documentation must be updated and presented to stakeholders during the Design Tollgate meeting:

    Documented Tollgate Meeting Minutes and Documented Stakeholder Approval to Proceed are outputs of every Tollgate meeting.

  17. Implement Design Document Change Control.
  18. Upon formal approval of the design document(s) by the appropriate TSPs, the Technology Solution Design documents are placed under change control. Any changes to the design documents must go through the CCB process, which is described in the TSLC Policy and the CCB Document Template.

  19. Upload Documents to the TSLC Artifacts Library.
  20. The BRM PM ensures that the following artifacts are uploaded to the TSLC Artifacts Library in the appropriate folders:

    Note: Baseline artifacts are indicated in this document by an asterisk (*).

    Tollgate process only: Tollgate artifacts must be uploaded within 10 business days of the Tollgate meeting.

PROCESS INPUTS/OUTPUTS

Baseline artifacts are mandatory and must be uploaded prior to release to production unless the project is following the Tollgate process. If Tollgate, documents from the Tollgate must be uploaded within 10 business days. Baseline artifacts are indicated in this document by an asterisk (*).
