Project management combines people skills, general management skills, ethical standards, logical sequencing, and problem solving. It is a dynamic profession. It differs across industries. The difficulty for both the learner and the instructor is that each brings their professional experiences into the learning environment.
The only way to mitigate this fact is to champion the fundamentals, to believe that the fundamentals, when properly executed, will work across industries. This requires the learner and the instructor to check their experiences at the door so that learning about the fundamentals can occur. This approach levels the playing field by making the focus theoretical based.
This takes the focus away from defending or attacking theories and instead directs the learning towards how best to utilize these fundamental concepts in the daily application of project management. I have taught many boot camps, collegiate courses, and conducted numerous corporate training engagements. Learning always occurs when we embrace the fundamentals.
