SE450: Incremental/Iterative Development [6/18]

When doing OO development, it has become clear over the years that the old style of waterfall life-cycle development consisting of analysis, design, and construction doesn't work (but companies companies continue to use it anyway).

This doesn't mean uncontrolled development with no planning

Instead, each increment of the system builds a subset of the entire system. An increment includes

• Conceptualization
• OO Analysis and Modeling
• OO Design
• Implementation (Coding, Testing, Integration)
• Packaging, optimization, etc (if delivered to an end user)
• Maintenance

Before the first increment is executed, an exploration phase is entered. This phase consists of

• Finding Use Cases
• Developing a model of the problem domain
• Developing an architecture
