Usage Phase
- Usage Phase
- the application life cycle
phase during which the latest version of the
application
is used by members of the
user organizations
The typical goals of the usage phase of an application
life project include:
- Keep the application functioning successfully until the
next major upgrade or retirement:
- Eliminate the endeavor’s highest risks.
To meet these goals, the typical objectives of the usage
phase include:
- Perform Content Management tasks.
- Perform Operations tasks.
- Perform Maintenance (defect fixes and minor enhancements)
tasks.
- Perform User Support tasks.
The following preconditions should typically be satisfied
before the usage phase can successfully begin:
- The data center is created.
- The production environment is installed and configured in
the data center.
- The application software is deployed to and configured in
the production environment.
- Transition testing has been passed.
- The customer organization and maintenance organization
have been trained in the application.
- The customer organization has transitioned to the new
business model.
- The user organizations have begun using the
application.
- The delivery phase has completed.
The following are the postconditions of the usage phase:
The usage phase is decomposed into the following builds and
milestones:
During the usage phase, the following work products are
typically produced:
The following aengineering activities and associated tasks
are typically performed during the usage phase in an iterative,
incremental, parallel, and timeboxed manner:
Administrative Activities and Associated Tasks
The following administrative activities and associated tasks
are typically performed during the usage phase in an iterative,
incremental, parallel, and timeboxed manner:
General Engineering Activities and Associated Tasks
The following general engineering activities and associated
tasks are typically performed during the usage phase in an
iterative, incremental, parallel, and timeboxed manner:
- If a new version of the application with major updates
are required, then these occur during the next development
cycle during which the initiation, construction, and delivery
phases are repeated.
