An engineer disassembles a lawnmower and notices an unusual wear pattern on a moving part. Following the Reverse Engineering process, the engineer documents the material used and justification for an improved material. Which part of the Reverse Engineering process did the engineer perform in this procedure?

Reverse Engineering is usually performed with the intention to construct a new device, program or parts that does the same thing without actually copying anything from the original. The r esulting knowledge gained can then be applied to the design of similar products and that capitalizing on successes and learning from the shortcomings of existing designs.
