A student builds a model bridge that collapses during a weight test. According to the iterative design cycle, what is the most logical next step?

Build an identical bridge, hoping for a different result.

Analyze the collapse to identify design weaknesses.

Abandon the project and start something completely new.

Conclude that the materials are unsuitable for bridge building.

An engineering team is designing a new drone. After the first test flight, they find its battery life is too short. What part of the iterative design process would involve changing the battery type or reducing the drone's weight?

The initial planning phase before any prototype is built.

The modification step that follows analysis of test results.

The final testing phase just before manufacturing.

The data analysis phase where the problem is first identified.

A chef follows a recipe exactly and serves a dish without ever tasting it.

An author writes a book, publishes it, and never revises it for future editions.

A car company gathers feedback on a new model to design an improved version for the following year.

A construction crew builds a house strictly following a blueprint that cannot be altered once work begins.

The process focuses on creating a single, final product without any testing.

Achieving a perfect solution on the very first attempt is the primary goal.

Solutions are improved through repeated cycles of building, testing, and analysis.

The initial plan is the most critical part and must be followed without changes.
