How does the Lean Startup's approach of "testing your vision continuously with your customers and making constant adjustments" fundamentally differ in practice from a more traditional "elaborate business plan and a product-centric approach"? What are the key trade-offs of each?

Synthesized answer

The Lean Startup's approach differs from a more traditional one by prioritizing continuous customer feedback and adjustments over an elaborate business plan and a product-centric approach [1]. Lean Startup prizes testing the vision continuously with customers and making constant adjustments [1]. In contrast, a traditional approach involves creating an elaborate business plan and focusing on the product itself [1].

The passages state that Lean Startup's methodology aims to prevent failure by finding out what customers will buy through "validated learning" about the customer, which involves getting continuous feedback to shift directions or alter plans [1]. The passages do not explicitly detail the key trade-offs of each approach, beyond implying that the traditional method, which leads to building something nobody wants, is a path to failure [1].
