As early as 1986 Fred Brooks brought forward the famous theory about" No Silver Bullet" in his distinguished discourse named No Silver Bullet: Essence and Accidents of Software Engineering ,considering there was no software method to solve the software crisis. Meanwhile,Mr. Brooks' bookmaking was regarded as the Bible of the domain of software engineering.

早在1986年，Fred Brooks先生在其著名的论文《No Silver Bullet： Essence and Accidents of Software Engineering》中就提出了著名的"没有银弹"的理论，认为在当时的10年之内不存在一种单纯的软件方法学可以解决出现的软件危机，而Brooks先生的《人月神话》更是成为了软件工程界圣经一般的读物。
