Not that it's the best or only methodology to project planning in a given scenario, company, or industry, but I do think there's significant value in PMP training. I completed the PMP exam in 2012 after being encouraged by a coworker, and I see it as both useful and cheap enough to suggest it to most software/hardware developers.

Learning and applying "how to plan a project" has pretty universal career relevance. I suggest 30-40 hours of study time, and it's around ~$600 to buy the book, take the exam, etc.
