The correct responses are:
- Document accurately
- Break down to the smallest level
- Use a systematic approach
Step-by-step explanation:
The three steps that are necessary to perform reverse engineering correctly are:
1. Document accurately: It is essential to document the existing product accurately to avoid missing any details that could affect the final design.
2. Break down to the smallest level: The existing product should be broken down into its smallest components to understand how they work and how they are interconnected.
3. Use a systematic approach: A systematic approach should be used to analyze the product, identify its components, and understand how they work together. This can help to ensure that the final design is accurate and functional.
Therefore, the correct responses are:
- Document accurately
- Break down to the smallest level
- Use a systematic approach
