@PeteS I've had my PMP since 2007. It's a must have for certain jobs/industries. For example, I am a program manager for US Gov't defense programs. It's a HUGE deal for this kind of work. In general, if your customers don't strongly desire the certification or if it's not required for advancing in your line of work, I wouldn't recommend it. It takes a considerable amount of time, money, and energy investment to get the certification. The reward has to be worth the investment, if you know what I mean.
Did this help, or was your question regarding how to get the certification?
