Object-oriented Analysis and Design
A Short Example 1
Define Use Cases
Play a Dice Game use case:
Player requests to roll the dice. System presents results: If the dice face value totals seven, player wins; otherwise, player loses. Die Game player Roll Dies

Object-oriented Analysis and Design
A Short Example 2
Define a Domain Model creating a description of the domain from the perspective of objects. There is an identification of the concepts, attributes, and associations that are considered noteworthy.
Player name 1 Plays 1 DiceGame 1 Includes 1 Rolls 2 Die faceValue 2

Object-oriented Analysis and Design
A Short Example 3
Assign Object Responsibilities and Draw Interaction Diagrams to illustrate these collaborations is the sequence diagram. It shows the flow of messages between software objects, and the invocation of methods.
