Hello everyone! 👋 If you’ve been in project management for a while, you probably remember the 10 knowledge areas from the PMBOK Guide 6th Edition: integration, scope, schedule, cost, quality, resources, communications, risks, procurement, and stakeholders. Now with the PMBOK Guide 8th Edition, the Project Management Institute streamlined that model into 7 performance domains. And I know what some people immediately think when they see that change: “Wait… where did the other areas go?” They didn’t disappear. They were simply restructured and integrated differently. PMI didn’t remove the knowledge. They reorganized it to better reflect something we already experience in real projects: everything is connected. If you want to understand how the performance domains evolved from the old knowledge areas, I explain it in my YouTube video: 🎥 English: https://youtu.be/TZMum9cuoJY 🎥 Portuguese: https://youtu.be/zuOtcz0QuBI Ricardo #ProjectManagement #PMBOK8 #PMI #ProjectLeadership #DeliveringValue
