- Knowledge - The engineer may be ignorant of that which is necessary to engineer a solution to the problem. This may be due in part to society (engineering organization, etc.) not having built or maintained the required infrastructure -- the schools, universities, and other institutions necessary for knowledge to be created, kept, and taught.
- Creativity - The engineer may not express the imagination/intelligence necessary to engineer a solution. This may be due in part to society (engineering organization, etc.) not creating or maintaining a nurturing artistic environment for the engineer.
