Final answer:
The Lean startup methodology favors Experimentation and Iteration, and Customer feedback, using a spiral design process for continual improvement. So the correct answer is C, D.
Step-by-step explanation:
The attributes favored by the Lean startup methodology are C. Experimentation and Iteration and D. Customer feedback. The Lean startup approach emphasizes the need to build a minimum viable product, test it with real customers, and use their feedback to make improvements.
This cycle of building, measuring, and learning is faster and more cost effective than traditional waterfall development methods which rely on elaborate upfront planning. Testing and evaluation of a prototype are crucial in the Lean startup, as they reveal the strengths and weaknesses of a product design.
This process necessitates iterating on the design based on the customer feedback received and the lessons learned from each test. Unlike the waterfall process, the Lean startup method supports a spiral design process that emphasizes ongoing refinement and optimization of the product.
