V (Visual Studio ALM Glossary)

This glossary defines key terms that are used in the Visual Studio Application Lifecycle Management (ALM) Help.

• validation
  Custom code that you can write to check a model for valid data and consistency between its elements. The domain-specific language framework also uses built-in constraints to validate models.

• validation test
  A test that ensures that the functionality called for in a scenario or quality of service requirement is working.

• velocity
  A measure of the work accomplished per unit of time, for example, iteration.

• velocity report
  A report that provides a measure of the rate of work accomplished per iteration unit of time, for example, iteration.

• version
  The status of an item in source control that reflects one or more changes from a previous form. The greater the version number, the more recent the version.

• version control
  The establishment and maintenance of baselines and the identification of changes to baselines that make it possible to return to the previous baseline.

• virtual environment
  An environment composed entirely of virtual machines.

• virtual machine
  A computer within a computer, implemented in software. A virtual machine emulates a complete hardware system, from processor to network card, in a self-contained, isolated software environment, enabling the simultaneous operation of otherwise incompatible operating systems. Each operating system runs in its own isolated software partition.

• Virtual Machine Manager
  Virtual Machine Manager (VMM) enables enterprise-wide management of virtual machines.

• Virtual Machine Manager agent
  Software that is installed on either a virtual machine host or a library server, which enables Virtual Machine Manager to monitor and manage hosts, virtual machines, and library resources. An agent is also installed on the source machine during a physical-to-virtual machine conversion.

• vision statement
  A short statement outlining the project vision, describing the value proposition, the stakeholders, and the driving factors.

• VMM
  See Virtual Machine Manager

• vulnerability
  Any weakness, administrative process or act, or physical exposure that makes a computer susceptible to exploit by a threat.
