• Are these “laws” of Belady and Lehman actually

• Could they be overcome with tools, education, discipline,

significant improvements in productivity?
– Within the past two years, Alan Greenspan and others have
claimed that IT has fundamentally changed the productivity of the
economy: “The synergistic effect of new technology is an
important factor underlying improvements in productivity.”
