Deployment

Definition

Deployment: the activity consisting of the cohesive collection of all tasks that are primarily performed to deliver, install, and configure all or part of a completed system, application, or component (e.g., database) to its production environments

As illustrated in the preceding figure, deployment is part of the following inheritance hierarchy:

The typical responsibilities of the deployment activity are to:

Formally transfer the completed system, application, or component from the development organization to the customer organization.
Prepare the system, application, or component for use by its user organization(s).
Deliver the final version of all deliverable work products to the customer organization.
Deploy the system, application, or component to its production environments.
Deploy the hardware components to their production environments.
Notify the user organizations regarding the readiness of the system, application, or component for use.
Ensure that user training occurs (see the training activity).
Ensure that the business procedures involving the new system, application, or component are updated to support it.

Deployment may typically begin when the following preconditions hold:

The system, application, data component, hardware component, or software component has passed system testing.
The delivery phase has started.
The project management Team is adequately staffed and trained in its deployment tasks.
The deployment team is adequately staffed and trained in its deployment tasks.

Deployment is typically complete when the following postconditions hold:

The system, application, data components, hardware components, or software components have been officially accepted by the customer organization.
The system, application, data components, hardware components, or software components are in use by the user organizations.
The delivery phase is complete.

The deployment activity typically involves the following producers performing the following deployment tasks:

The following diagram illustrates the temporal relationships between the deployment tasks.

The deployment activity typically involves the following environments:

The deployment activity typically results in the production deployment work products:

The deployment activity typically involves the following phases:

This activity is documented using the typical configuration for large projects. It is intended to be configured (i.e., instantiated, extended, and tailored) to meet the needs of specific projects.
The preconditions of this activity should be the union of the preconditions of its constituent tasks.
The completion criteria for this activity should be the union of the postconditions of its constituent tasks.
