Some Questions on laws related to Software Engineering Ques1: Describe each law in your own words. Illustrate with a practical example. Ans1: Glass’ Law: “Requirement deficiencies are the prime source of project failures” Lack of requirements is the major root cause of unsuccessful projects. The major reason of project failure is lack of requirements. Requirements are usually defined in first phase of project development and if not defined properly may cause problems in further stages and ultimately
