Which term describes a program design methodology that allows the system developer to define the system software in convenient stages?

• A. Spiral Development
• B. Readability
• C. Incremental Development
• D. Programming Style

Answer: (C)

Building software in convenient stages by adding functionality in increments is a common approach for managing complexity and embracing change. In incremental development, the system is divided into small, workable pieces that can be planned, implemented, tested, and delivered one after another. Each increment delivers a usable subset of features, allowing early feedback and adjustments before the next set of features is added. This makes it easier to plan and manage the project, integrate components, and verify the system step by step.

Spiral development also involves iterations, but it centers on risk assessment and refining prototypes through repeated cycles, rather than primarily focusing on delivering features in stages. Readability and programming style describe code quality aspects rather than a methodology for structuring the system’s development over time.
