PMP Certification is popular and requires 35 hours of project management training before you can sit for the PMP Exam.
PMP certification doesn't make sense for every person who leads a project. It is best for people who have committed to a career in project management. And even organizations that are strongly project-driven have opted not to value the PMP certification, choosing instead to promote project management training that builds skills and is aligned with their own processes.
The PMO should be an active participant in this ongoing discussion about the value and proper place the PMP certification holds in an organization. This video from www.pmi.org adds a personal perspective.
