Study Notes
Introduction to Rapid Application Development (RAD)
- Rapid Application Development emerged in the 1980s as a response to traditional waterfall development practices.
- RAD conceptualizes software development as a flexible process, likening software to clay rather than steel, emphasizing adjustability.
Characteristics of RAD
- RAD promotes rapid prototyping over extensive planning, allowing projects to adapt as they evolve.
- Unlike traditional engineering, where designs are fixed, software can be modified and updated throughout the development process.
Historical Context of Software Development
- In the 1970s, software development required extensive planning and time-consuming development phases akin to physical engineering projects.
- Initial practices involved drafting functional requirements, resulting in lengthy timelines before stakeholders saw any product.
Waterfall Model
- The traditional waterfall model entails a linear approach: starting with requirements, then moving to design, development, and ending with user delivery.
- Changing requirements mid-project in waterfall methodology can be prohibitively expensive, akin to modifying physical resources like wood or cement.
Evolution of RAD
- In the 1980s, innovators like Barry Boehm and James Martin recognized the flexibility of software and developed models like the Spiral Model and Martin's RAD model.
- These models laid the groundwork for later methodologies, influencing the creation of Agile.
RAD vs. Agile
- RAD is often confused with agile methodologies but they are fundamentally different: RAD is a specific methodology while Agile represents a broader philosophy.
- RAD focuses on delivering projects quickly with adaptive processes, while Agile encompasses additional principles beyond just development tactics.
Core Principles of RAD
- A key principle of RAD is the importance of customer satisfaction through early and continuous delivery of valuable software.
