What development methodology includes adaptive planning, early delivery of partial solution pieces, continuous improvement, and delivering products with the minimum amount of work?

Options

• ASpiral model
• BWaterfall model
• CPrototyping with strict enforcement of corporate standards for consistency
• DAgile development model

Explanation

Agile development (D) is defined by exactly these four traits: adaptive (not fixed) planning, incremental early delivery, continuous improvement through retrospectives, and a "minimum viable" mindset that avoids unnecessary work - making it the only choice that matches all four criteria simultaneously.

Why the distractors fail:

• A. Spiral model focuses on iterative risk analysis and uses repeated cycles, but its planning is not inherently adaptive and it doesn't emphasize minimum work.
• B. Waterfall is the opposite of adaptive - it requires all requirements upfront, delivers the full product only at the end, and discourages changes mid-process.
• C. Prototyping with strict corporate standards contradicts "minimum amount of work" and "adaptive planning," since enforcing rigid standards adds overhead and reduces flexibility.

Memory tip: Think of the word AGILE itself - Adaptive, Gradual delivery, Iterative improvement, Lean (minimum work), Early release. If a question lists those concepts together, Agile is almost always the answer.
