Professional Certifications (PMP/ITIL/Scrum/Six Sigma)
Four standalone, widely-recognized professional certifications — project management (PMP), IT service management (ITIL), Agile delivery (Scrum), and process quality (Six Sigma) — each valuable independently, not a single linear curriculum.
Unlike most roadmaps on this platform, these four certifications aren't sequential steps toward one role — they're four separate, real credentials a professional picks based on their actual career direction (delivery/PM, IT operations, Agile teams, or process improvement). This roadmap surveys all four at overview + fundamentals depth so you can compare and pick the one relevant to your role before going deeper.
Each certification has its own independent exam and eligibility path (PMP requires documented project-management experience hours; ITIL/Scrum have shorter, more accessible entry certifications) — pick one based on your actual career direction rather than pursuing all four.
