PMI-SP case studies
PMI-SP · Put your knowledge to work in context.
The PMI Scheduling Professional (PMI-SP)® is one of the specialized certifications offered by the Project Management Institute, listed by PMI alongside its risk, business analysis, agile, construction, and PMO credentials. It is aimed at practitioners whose core responsibility is building, maintaining, and defending project schedules rather than at general project managers: schedulers, planners, schedule analysts, cost/schedule integrators, and project controls specialists who work inside earned value or critical-path-driven environments. The PMI-SP case studies are 5 cases and about 3,886 words.
