Inspections were first proposed by Fagan in 1976. These inspections are called Formal Inspection or Fagan Inspection (or sometimes just Inspection).Compared to other inspection techniques Formal Inspections follow a stricter or formal (well-defined) process.The following classification of inspection techniques with respect to their degree of formality was proposed by Wiegers [1]. Formal Inspections are the most formal technique while Ad hoc Review is the least formal one. Team review, Walkthrough, Peer Deskcheck and Passaround are between these two extremes. For practical use these techniques often have to be adapted.
