EXMP case studies
EXMP · Put your knowledge to work in context.
EXMP is a professional certification exam structured around seven domains that together describe the full lifecycle of a technical project: fundamentals and core concepts, planning and requirements analysis, design and architecture, implementation and configuration, testing and quality assurance, operations and troubleshooting, and security, compliance, and risk management. The credential is intended for practitioners who both plan and build working systems, and who are expected to reason across domain boundaries rather than specialize narrowly. The EXMP case studies are 5 cases and about 2,752 words.
