If one does an internet search, many more hits are returned relating to project lifecycle management vs. project lifecycle governance, and added in for additional confusion and overlap are hits related to PPM and ALM. Why is this? A few reasons come to mind. Big software companies with big marketing tend to drive the software category names. They have chosen to associate their products with the "Management" linkage to projects, applications and portfolios. Governance sometimes has a negative connotation of "Big brother" looking over the IT organizations shoulder with a bureaucratic stigma attached.
