Watson remarks that Holmes always baffles him with these deductions, even though his eyesight is just as good as Holmes. Sherlock replies, "You see, but you do not observe. " Detecting and debugging differ in the extent to which we can create additional evidence. Detectives can take things from a crime scene and have them analyzed and identified. All forensic analysis, however, is after the fact. When we debug software, we can repeat the defective behavior and observe what we want to see. For a detective, it would be the equivalent of going back in time and planting a video camera at the scene of the crime.

They each produce a tangible result. Coding produces source code. Designing produces design documents. Analysis produces a variety of documents, depending on the methodology used. Testing produces test cases and reports on the success or failure of tests. In contrast, debugging is primarily a cognitive activity. The end result is knowledge of why there is a problem and what must be done to correct it. There will be a source change, but it may only involve adding or deleting a single character or word.
