We tend to blame the physical media for most of our implementation difficulties; for the media are not "ours" in the way the ideas are, and our pride colors our judgement.

I am more convinced than ever. Conceptual integrity is central to product quality.

When a task cannot be partitioned because of sequential constraints, the application of more effort has no effect on the schedule. The bearing of a child takes nine months, no matter how many women are assigned.

How does a project get to be a year behind schedule? One day at a time.

Predictability and great design are not friends.

A scientist builds in order to learn; an engineer learns in order to build.

Successful software always gets changed.
