Laws of Software Engineering

The Brooks cluster

One author whose work shapes most of the field.

Why these together

Four entries from The Mythical Man-Month (and No Silver Bullet), each a distinct claim. Brooks's Law covers adding people. No Silver Bullet covers essential and accidental complexity. Conceptual Integrity covers design coherence. The Surgical Team covers small expert teams. Together they make Brooks the most-cited author in the index, and half a century after publication the reasons still hold.

• Pattern Brooks's Law Adding people to a late project makes it later.
• N Principle No Silver Bullet There is no single technique that will produce a ten-fold improvement in productivity within a decade. The hard part is the essential complexity of the problem itself.
• C Principle Conceptual Integrity A system designed by one mind, or by a few minds in close agreement, will be easier to use and understand than one designed by committee.
• T Pattern The Surgical Team A small team of high-talent specialists, organised around a chief programmer, outperforms a larger mixed team on coherent work.
