No silver bullets. Really!

Fred Brooks wrote a seminal essay in 1986, “No Silver Bullet — Essence and Accidents of Software Engineering“, a model of clear and cogent thinking that I consider to be required regular reading for anyone involved in information technology.  Despite the essay’s brilliance, and despite its wide promulgation and deserved fame, the phenomenon it describes seems to have only broadened in the last twenty-three years.  Brooks argues as follows (with bolding added):

The familiar software project, at least as seen by the nontechnical manager, has something of this character; it is usually innocent and straightforward, but is capable of becoming a monster of missed schedules, blown budgets, and flawed products. So we hear desperate cries for a silver bullet—something to make software costs drop as rapidly as computer hardware costs do.

There is no single development, in either technology or in management technique, that by itself promises even one order of- magnitude improvement in productivity, in reliability, in simplicity.”

So this basic tenet has been convincingly articulated by a leading IT thinker for almost a quarter century. Yet, the trend continues: new technologies pop up every couple of years and the hype cycle begins. Evidently, hope springs eternal.
