Scaled Agile Framework / SAFe Scrum Master Certification Prep (SSM) 2023 with complete solution

job sequencing the key to economic outcomes WSJF weighted shortest job first How do you calculate WSJF? WSJF = CoD (estimated value) / Duration (time to ship or Job Size) RR risk reduction OE opportunity enablement How to calculate CoD? CoD = User-business value + Time criticality + RR & OE value / Job Size or "Duration" PI program increment NFR non functional requirement 3 Pillars of Scrum transparency, inspection, adaptation Scrum values make these things transparent: process, workflow, progress The 5 SAFe Scrum Values are... courage, focus, openness, commitment, respect SAFe Iteration length 2-4 weeks Team composition does not change during an Iteration, otherwise the ____ is invalid. velocity product owner owns, prioritizes and manages the TEAM backlog team increment a thin vertical slice of functionality Three roles in Agile teams scrum master, product owner, development team Typical development team size in Scrum 3-9 excluding the scrum master and product owner The promise of SAFe Synchronizes alignment, collaboration, and delivery for large numbers of teams 4 core values of SAFe built-in quality, program execution, alignment, transparency 9 SAFe Lean-Agile principles 1. take an economic view 2. apply systems thinking 3. assume variability; preserve options 4. build incrementally with fast, integrated learning cycles 5. base milestones on objective evaluation of working systems 6. visualize and limit WIP, reduce batch sizes, and manage queue lengths 7. apply cadence, synchronize with cross domain planning 8. unlock the intrinsic motivation of knowledge workers 9. decentralize decision making Agile Release Train a virtual organization of 5-12 teams (50-125+) that plans, commits, and executes together program increment duration a fixed timebox with a default of 10 weeks.
