Mutual Relationship amongst Change Management, Project Management and Business Analysis

Let me establish the relation amongst Project Management, rather I would say Organizational Project Management (which includes Projects, Programs and Portfolios), and Organizational Change Management and Business Analysis. I agree that these are all separate specializations but in heart of their hearts, they are all related and connected. A project manager has a right to be exposed to all of them and be able to make the best decisions based on this knowledge. Organizational Project Management is all about change and is governed under the same Organizational Strategy which germinates Organizational Change Management. Business Analysis is the instrument connecting these two. If there is a change required at organizational level to satisfy the strategic needs, business analyst creates the business case and establishes the requirements. Once the change is justified through a feasibility and is agreed to be acted upon, that is the time the organizational project management comes into action. The programs realize benefits and projects deliver product, service or result, all in alignment with organizational strategy and objectives.

I do agree there are different scope and processes for Organizational Change Management, Business Analysis and Organizational Project Management, but the difference is not that wide as they all intersect each other at some point.

If only to avoid any confusion, I may agree to study all of these separately but otherwise we cannot ignore the mutual relationship of three concepts.
