Tom DeMarco (born 20 August 1940) is a well-known author, teacher, and speaker on software engineering topics. He was the 1986 recipient of the Warnier Prize for "lifetime contribution to the field of computing," and the 1999 recipient of the Stevens Award for "contribution to the methods of software development".


  • You can't control what you can't measure

  • The business of software building isn't really high-tech at all. It's most of all a business of talking to each other and writing things down. Those who were making major contributions to the field were more likely to be its best communicators than its best technicians.

  • It's not what you don't know that kills you but what you know that isn't so.

  • A day lost at the beginning of project hurts just as much as a day lost at the end.

Quotes about Tom DeMarco[edit]

  • Systems engineering as an approach and methodology grew in response to the increase size and complexity of systems and projects... This engineering approach to the management of complexity by modularization was re-deployed in the software engineering discipline in the 1960s and 1970s with a proliferation of structured methodologies that enabled the the analysis, design and development of information systems by using techniques for modularized description, design and development of system components. Yourdon and DeMarco's Structured Analysis and Design, SSADM, James Martin's Information Engineering, and Jackson's Structured Design and Programming are examples from this era. They all exploited modularization to enable the parallel development of data, process, functionality and performance components of large software systems. The development of object orientation in the 1990s exploited modularization to develop reusable software. The idea was to develop modules that could be mixed and matched like Lego bricks to deliver to a variety of whole system specifications. The modularization and reusability principles have stood the test of time and are at the heart of modern software development.
