Harvard Business School

The mission of HBS's Doctoral Programs is to develop outstanding scholars for careers in research and teaching at leading business schools and universities. To ensure a solid foundation in management, all students (without an MBA degree) are required to take at least five courses in the MBA curriculum. A deep knowledge of management practice—not only in general, but also specific to a student's area of specialization—is a critical component of business doctoral education. These courses provide a valuable source of research topics and institutional knowledge that will be important for future research and teaching success in business schools. At the same time, a broad knowledge of business ensures that students fully appreciate the interdependencies and complexity of management problems and may introduce them to the possibility of interdisciplinary research.
All students are admitted for full-time degree programs, beginning in September. Students, however, may begin the program in July, conducting research with an HBS faculty member. A minimum of two years in residence is required, and it is expected that students will complete their program in four to five years. Students typically spend two to two-and-a-half years on course work, and another two years on their dissertation. This is wikipedia info!
