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.
RTE role
acts as chief scrum master for the train
product manager
owns, defines, and prioritizes the PROGRAM backlog
system architect/engineer
provides architectural guidance and technical enablement to the teams on the train
business owners
key stakeholders on the agile release train
4 program events
PI planning
ART sync
System Demo
Inspect and Adapt event
PI planning timebox
2 days
art sync timebox
1 hour
system demo timebox
2 hours
inspect and adapt event
the train reviews and improves its process before the next PI
pdca
plan, do, check, act
PI planning cadence
2 days every 8-12 weeks (10 is typical)
Product Management role in PI
owns feature priorities
Development teams role in PI
own story planning and high level estimations
Two things every feature has
benefit hypothesis and
acceptance criteria
benefit hypothesis
justifies feature implementation cost and provides business perspective when
making scope decisions
When is acceptance criteria typically defined?
during program backlog refinement
What are the 3 C's of user stories?
