Application Development Cycle
An
application development cycle is the
cycle consisting of all
phases during which a single
application is produced and delivered.
The typical goals of the application development cycle are
to:
- Develop a single application that meets the needs of its
customer organization.
- Deliver the application to the customer
organization.
The typical objectives of the application development cycle
are to:
- Provide an overview to the development project as a whole
in terms of its phases.
- Provide overall organization to its activities and
milestones.
- Support top-level scheduling of activities, personnel,
and resource acquisition.
The application development cycle typically includes the
following phases:
-
Initiation, which is the first application life cycle phase during
which the application's initial vision, major requirements,
and partial architecture are captured so that the
application's scope can be estimated.
-
Construction, which is the second application life cycle phase during
which the
complete version of the application is
developed.
-
Delivery, which is the third application life cycle phase during
which the new version of the application is delivered to the
customer organization and placed into use by the user
organizations.
The following figure illustrates the application development
cycle including its phases and position within the overall
business engineering cycle:
- Different cycles contain different phases, depending on
the mission of the endeavor.
- Cycles and phases can be combined or decomposed depending
on the need for these stages to better map to engagements and
contracts between the various organizations.
