Do organizations need a PMO or a project management department?

In this post, I am sharing a video from the Applied Project Management by SUKAD YouTube channel. This video is from the first project management forum organized in Dubai; the Dubai International Project Management Forum (DIPMF).
The video is about PMO, Project Management Office and makes the case to elevate the status of PMO and Project Management in organizations from an “office” to a formal “department”. In other words, is there a need to transform from PMO to project management department?
The video is via this link. It is 27 minutes but because it was a live event; the sound quality is not best.
