►
The gathering of details about what needs
to be done, and how the application should
perform those tasks.
Actors: Business Analysts

Design
► High-level
design of the application to specify
how the application will be created.

Coding/Implementation
► Involves
writing the code for the application
using the chosen programming language and
software platform from the design phase.
► Actors:

Testing
► The
testing phase covers the process of
planning tests that will be run on the
application to examine its functionality.
