Requirements Analysis

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

6
Coding/Implementation

• Involves writing the code for the application
  using the chosen programming language and
  software platform from the design phase.

7
Testing

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

Deployment/Maintenance

• Release the application to users and manage any
  problems that might occur when the users are
  using the software.

• If youre testing the requirements process
• Ad-hoc
• If you dont have a test plan
• Performance
• If youre testing how the application responds

12
Testing Types (Cont)
