Which sequence correctly lists the three steps of reverse engineering?

• A. Structural Analysis, Visual Analysis, Functional Analysis
• B. Visual Analysis, Functional Analysis, Structural Analysis
• C. Functional Analysis, Visual Analysis, Structural Analysis
• D. Visual Analysis, Structural Analysis, Functional Analysis

Answer: (B)

Reverse engineering follows a logical progression from external observation to function to internal structure. Start with Visual Analysis: look at the object’s appearance, features, size, markings, materials as you can observe without taking anything apart. This builds a clear, non-destructive picture of what you’re dealing with and helps you plan the next steps. Next is Functional Analysis: determine how the device operates, what inputs it accepts, what outputs it produces, how energy or motion flows, and how the user interacts with it. Understanding these functions tells you what the design must achieve and guides you to what subsystems and components are likely involved. Finally, Structural Analysis examines the internal arrangement: components, layout, materials, and manufacturing methods that enable the identified functions. With a defined purpose from the functional analysis, you can map each internal part to a function and see how the design achieves the overall performance. This order is effective because knowing the intended function directs your inquiry into the internal structure, and starting with visual cues helps avoid unnecessary disassembly or misinterpretation. Other sequences that skip steps or reorder them can lead to overlooking how the device is meant to work or misidentifying internal components.
