Kelly, there's a reason why PMI puts statements all throughout the BOK that you have to have some familiarity with your industry as to how you apply project management standards. Even in my own agency we engage in that conversation. For instance, I'll keep project management standards in mind on a small project, but I'm not likely to actively engage in developing a detailed project management plan and implementing stringent controls simply because of cost, and time feasibility issues. Whereas on a larger project that has more inherent risks because it has more players involved, absolutely I'm going to engage in a more detailed model of project management planning. So some of this is knowing when to take it or leave it and that's where experience and guidance from more senior PMs comes in. The credentialing in my opinion just means you understand the standard jargon and can follow along until you develop your own experience and reputation.
