VVSG Use Cases

READ-ONLY SITE MATERIALS: Historical voting TWiki site (2015-2020) ARCHIVED from


This topic is for the discussion and development of the scope (use cases) for the Next Generation VVSG.

  • An initial document capturing preliminary thoughts on scope and structure is located here in PDF formats.
  • The scope section of the VVSG Scope and Structure Document contains use case scenarios for the Next Generation VVSG.


This document provides a summary of the focus areas for development of the Next Generation VVSG by the NIST Voting Public Working Groups. These focus areas were identified during the February, 2016 TGDC meeting. For each area, we highlight the typical use case scenario as well as common variations. They represent starting points for discussion, not necessarily areas to be included in the standard in totality. As such, we need to determine which areas or subareas are in scope for this ongoing work.

Specifically, we are requesting your feedback regarding which use case scenarios should be included in the development of the Next Generation VVSG.

Request for Feedback

For each use case scenario, please address these questions:

  1. Is the use case scenario in scope for the Next Generation VVSG for development of requirements that will undergo testing and certification? or

  2. Is the use case scenario in scope to develop as guidelines for election officials and voting system manufacturers? or

  3. Is the use case scenario not in scope for this work?

  4. If different parts of the use case scenario fall in 1., 2., and/or 3. Please identify as such.

  5. Is anything missing?

Overview of Focus Areas

Each area is defined by the processes and functions it supports. The set of identified use-cases are also, in some cases, highly interdependent. Thus, a given function may occasionally be reused in more than one case.

The current set of use case scenarios include:

The following diagram visualizes the use-cases in the context of a typical election process. The accompanying table describes the meaning of each abbreviation used throughout this document.

Voting TWiki Archive (2015-2020): read-only, archived wiki site, National Institute of Standards and Technology (NIST)


This page, and related pages, represent archived materials (pages, documents, links, and content) that were produced and/or provided by members of public working groups engaged in collaborative activities to support the development of the Voluntary Voting System Guidelines (VVSG) 2.0. These TWiki activities began in 2015 and continued until early 2020. During that time period, this content was hosted on a Voting TWiki site. That TWiki site was decommissioned in 2020 due to technology migration needs. The TWiki activities that generated this content ceased to operate actively through the TWiki at the time the draft VVSG 2.0 was released, in February of 2020. The historical pages and documents produced there have been archived now in read-only, static form.

  • The archived materials of this TWiki (including pages, documents, links, content) are provided for historical purposes only.
  • They are not actively maintained.
  • They are provided "as is" as a public service.
  • They represent the "work in progress" efforts of a community of volunteer members of public working groups collaborating from late 2015 to February of 2020.
  • These archived materials do not necessarily represent official or peer-reviewed NIST documents nor do they necessarily represent official views or statements of NIST.
  • Unless otherwise stated these materials should be treated as historical, pre-decisional, artifacts of public working group activities only.
