What is the first Agile Manifesto Principle?
Our highest priority is to satisfy the customer through early and continuous delivery of variable software.
Slide: 58
What is the second Agile Manifesto Principle?
Welcoming changing requirements, even late in development. Agile processes harness change for the customer’s competitive advantage
Slide: 58
What is the third Agile Manifesto Principle?
Deliver working software frequently, from a couple of weeks to a couple of months, with a preference for the shorter timescale.
Slide: 58
What is the fourth Agile Manifesto Principle?
Business people and developers must work together daily through the project.
Slide: 58
What is the fifth Agile Manifesto Principle?
Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.
Slide: 58
What is the sixth Agile Manifesto Principle?
The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
Slide: 58
What is the seventh Agile Manifesto Principle?
Working software is the primary measure of progress
Slide: 59
What is the 8th Agile Manifesto Principle?
Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
Slide: 59
What is the 9th Agile Manifesto Principle?
Continuous attention to technical excellence and good design enhances agility.
Slide: 59
What is the 10th Agile Manifesto Principle?
Simplicity - the art of maximizing the amount of work not done - is essential.
Slide: 59
What is the 11th Agile Manifesto Principle?
The best architectures, requirements, and designs emerge from self-organizing teams.
Slide: 59
What is the 12th Agile Manifesto Principle?
At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behaviour accordingly.
Slide: 59
How many Agile Manifesto Principles are there?
12
Slide: 59
What are the 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 size, and manage queue lengths
7) Apply cadence, synchronize with cross-domain planning
8) Unlock the intrinsic motivation of knowledge workers
9) Decentralize decision making
10) Organize around value

slide 61
what is PDCA?
The iterative learning cycle
Plan Do Check Act
slide 78
What is the iterative learning cycle?
PDCA - Plan Do Check Act
slide 78
What is the problem of phase-gate milestones?
they force design decisions too early, which encourages false-positive feasibility
they assume a point solution exists and can be built correctly the first time
they create huge batches and long queue, and they centralize requirements and design is program management
slide 82
With regards to solution economic trade-offs, if you only quantify one thing, what should it be?
the cost of delay
slide 68
What are the trade-off parameters for the solution economic trade-offs?
lead time
production cost
value
development expense
and risk
slide 68
What should you focus on when optimizing the full value stream?
the delays
slide 72
In order to preserve options, what approach should you use?
Set based approach
slide 78
Explain Program Increment (PI) System Demos
are orchestrated to deliver objective progress, product, and process metrics
slide 84
What do objective milestones facilitate?
learning and allow for continuous, cost-effective adjustments towards an optimum Solution
slide 85
List some of the reasons it is important to use small batch sizes.
Large batch sizes increase variability
High utilization increase variability
severe project slippage is the most likely result
small batches go through the system faster with lower variability
the most important batch is the handoff batch
slide 93
How do you find the optimal batch size?
determine the lowest point of the u-curve for holding costs and transaction cost
slide 94
What does reducing batch size do?
increases predictability
accelerates feedback
reduces rework
lowers cost
slide 95
What is the formula for little’s law?
Average wait time = average queue length / average processing rate
slide 98
What does Little’s law state?
faster processing time decreases wait
shorter queue lengths decrease wait
slide 98
Describe cadence
converts unpredictable events into predictable occurrences and lowers cost
slide 100
Describe synchronization
causes multiple events to happen simultaneously
slide 100
Can you have cadence without synchronization?
no
slide 101
How can you limit variability to a single interval?
cadence-based planning
slide 103
Who is the most qualified to make decision about how workers perform their work?
the workers
slide 106
What is autonomy?
the desire to be self-directing and have control over what we work on, how we do our work, and who we work with
slide 107
What is mastery?
the urge to get better at what we do and improve our personal and team skills
slide 107
What is purpose?
the desire to do something that matters and has meaning
slide 107
What is a value stream?
the sequence of steps used to deliver value to the Customer
