Business Environment weight jumps from 8% to 26%
MajorThe single biggest weight shift. Previously a small slice, Business Environment now covers about a quarter of the exam — strategy alignment, compliance, benefits realization, organizational change, and external business factors all get more questions.
Candidates whose prep materials were tuned to the 2021 ECO (8% Business Environment). That includes Rita Mulcahy 10th edition, older Andrew Ramdayal Udemy versions, and PMI Authorized Training Partner content from before July 2026.
Verify your prep materials are calibrated to the 2026 ECO. Add a dedicated 1–2 week block on Business Environment topics if your source under-covers it.
