The meaning of "senior" in "Senior Project Manager"

A senior project manager may be someone who does not even have a PMP certificate, and I truly and honestly do not believe that any certification scheme including the PMP/PMI thing is an alternative to knowledge, experience and wisdom in this regard.

A senior project manager may be someone with real-life successful experience, good personal communications skills, negotiation skills, conflict and crisis management/resolution, overall maturity/exposure in the field.

Personally, I have a Certified Project Manager (CPM) and Certified Project Director (CPD) from IAPPM, but I count on my own professional experience and successful project delivery since I was with IBM more than I count on certifications.

You also know that I have my Advanced Project Management Topics" (APMT) with its 2000+ members and focus on such topics as project portfolio management (PPM), program management, project/program management office (PMO), project management maturity model (PMMM), project manager capacity assessment (PMCA), organizational project management maturity model (OPM3), and so on so forth.

Lastly, the word "senior" in "senior project manager" does not and should not relate to professional certifications like PMP, and it should not relate (positively or negatively) to the age of the candidate. The word senior is more related to experience, exposure, capability, maturity and wisdom of the individua
