The course work for a business degree at Ohio State eventually required specialization. Specialization coursework involved about 25 hours of three and four hundred level courses in a specific business disciplines like Marketing, Human Resources, Accounting, Logistics, etc; I chose Production and Operations. One of my course books dedicated a 40 page chapter and nearly a whole week to Project Management.
I surmise that many other discipline course works provided a similar introduction to Project Management. Project Management must be introduced to other disciplines like Engineering, Computer Science, Health Care, and most other fields. Every functional area and discipline has projects. I saved my College books when a new edition was published and the book had no resale value. My career matured and I used that 40 page PM chapter college book as a blueprint for the projects that I ran as a functional manager.
