"One of the best ways to understand a product or device is through reverse engineering—it's a hands-on way to satisfy one's curiosity about what's inside a product and how it works, or to fix a device when instructions are lost or unclear. Reverse engineering is often part of the engineering design process—used to make imitation products or innovate improvements. Reverse engineering cultivates many skills that are important in engineering, including teamwork, tool usage, communication (writing a manual and report, creating graphic images, giving oral presentation), sketching and coming up with design improvements." - From teachengineering.org
