2 Program Development Life Cycle
►Set of phases and steps that are followed by
developers to design, create, and maintain a
computer program
• Gather and Analyze the Program
Requirements
• Design the User Interface
• Design the Program Processing Objects
• Code the Program
• Test the Program
• Document the Program/System
• Maintain the Program/System

Phase I: Gather and Analyze the
2 Program Requirements
►Gather project requirements by interviewing
users, reviewing current procedures, and
completing other fact-gathering tasks
►Two types of requirements documentation
• Requirements document
• Use Case Definition


2 Phase 2: Design the User Interface

►Developers sometimes spend 25% to 40% of the
program design time on the user interface
• Presentation layer
►Use Visual Studio to create the user interface
►Interface designs are often called mock-ups



►Principles of User Interface Design
• The GUI should be easy to use and follow
►Users will not be satisfied with the application if the
user interface is not easy to use
• Three primary means of interacting in a user
interface are the keyboard, a pointing
device, and voice input
• Use of the interface should feel natural and
normal
• Provide the most appropriate object for each
requirement


• Once an object is used for a particular
purpose, then that object should be used for
the same purpose throughout the program
interface
• Arrange objects in the sequence in which they
are used
• The interface should be kept as simple as
possible, while maintaining functionality
• The user interface should be intuitive
