According to version 1.6 of the BABOK, Enterprise Analysis is the strategic part of the project life cycle. It includes
- developing strategic goals and a strategic plan to get there,
- understanding and developing the business architecture,
- selecting the right solution approaches for projects and developing their business cases, and
- initiating projects and making sure they deliver value to the sponsor
All of these things are strategic activities that bookend the project life cycle.
Chapter 2 of the BABOK (v1.6) describes these activities in more detail and you should go check it out today. It’s a fascinating topic and I commend the IIBA for including it in the practitioners’ guide.
