An improved inspection technique

Software reviews are not a new idea. They have been around almost as long as software has. One ofthe most natural ways to check if something is correct is to look at it. Babbage and von Neumann regularly asked colleagues to examine their programs [6]. In the 1950s and 1960s, large software projects often included some sort of software review. By the 1970s, various review methods had emerged with different names: software reviews, technical reviews, formal reviews, walkthroughs, structured walkthroughs, and code inspections. Each review method had different forms to fill out, different review team sizes and makeup, and so on, but none suggested any approach for reviewing the software or other work product other than just looking at it and discussing it
