Introduction to Interfaces
There are many areas where P3 management interfaces with other disciplines. Project, programme and portfolio managers need to have an understanding of how disciplines such as law, accounting and HR management impact upon their work.
They do not have to become experts in these disciplines, but they do need to understand them sufficiently in order to look for expert help and to ask the right questions.
The need to understand these disciplines increases with the progression from project to portfolio-level management. Managers of smaller projects will rely on specialist support from within their organisation, whereas managers of portfolios will often need a good understanding of these topics at a strategic level.
