THE OLD WAY AND THE NEW • Conventional software engineering has numerous well-established principles. Many are still valid; others are obsolete. • A modern software management process will incorporate many conventional principles but will also transition to some substantially new approaches.

• Many of the conventional management and technical practices have been replaced by

• Many of the conventional management and technical practices have been replaced by new approaches that combine recurring themes of successful project experience with advances in software engineering technology. • This transition was motivated by the insatiable demand for more software features produced more rapidly under more competitive pressure to reduce cost.
