Q
SAFEe Lean-Agile Principles
A
MISMOVED WC
- Base milestones on objective evaluation of working systems - PI demos orchestrated to deliver objective progress, product, and process metrics
- Build Incrementally with fast, integrated learning cycles - facilitated by small batch sizes, requires increased investment in development environment, integration points reduce risk
- Apply systems thinking - system can evolve no faster than its slowest integration point, optimize value stream
- Unlock intrinsic motivation of knowledge workers
- Organize around value - not silos
- Assume variability, preseve options
- Take an economic view - deliver early and often, apply an economic framework
- Decentralize decision-making
- Visualize and limit WIP, reduce batch sizes, manage queue lengths
- Apply cadence, synchronize with cross-domain planning
11
Q
Elements of applying an economic framework (part of principle #1)
A
- Operating within lean budgets and guardrails
- Understanding solution economic trade-offs (lead time, product cost, value, development expense, risk)
- Leveraging suppliers
- Sequencing jobs for the maximum benefit
12
Q
Primary aspects of systems thinking (part of principle #2)
A
- Solution itself is a system
- Enterprise building the system is a system too
- Optimize the full value stream
13
Q
Why limit WIP? (related to principle #6)
A
Confuses priorities, causes frequent context switching, and increases overhead. It overloads people, scatters focus on immediate tasks, reduces productivity, and throughput, and increases wait times for new functionality.
14
Q
Basic building block when organizing around value (part of principle #10)
A
Agile teams are cross-functional, which enables them to define, build, test, and where applicable deploy elements of value quickly with a minimum of handoffs and dependencies.

48
Difference between feature and capability
Feature - fulfills a stakeholder need. Each feature includes a benefit hypothesis and acceptance criteria, and is sized or split as necessary to be delivered by a single ART
Capability - higher-level solution behavior that typically spans multiple ARTs. Capabilities are sized and split into multiple features to facilitate their implementation in a single PI
49

3. Built-in Quality – All Agile teams apply defined Agile practices to create high-quality, well-designed solutions that support current and future business needs.
55
Refactoring
Activity of improving the internal structure or operation of a code or component without changing its external behavior
56
Spikes
Type of exploration Enabler Story. Represent activities such as research, design, investigation, exploration, and prototyping. Purpose is to gain the knowledge necessary to reduce the risk of a technical approach, better understand a requirement, or increase the reliability of a story estimate. Demonstrated at the end of an iteration. Do not directly deliver user value
57
Two types of spikes
Functional - How to break it down, organize the work, where risk and complexity exist, how to use instights to influence implementation decisions
Technical - Determine build vs buy, evaluate potential performance or load impact, evaluate specific tech implementation approaches, develop confidence about desired path

- Approve significant activities
- Continuous business owner engagement
64
What is a set-based design approach? (part of principle #3 - assume variability / preserving options)
Considering multiple design options up front instead of single option up front and then adjusting. Keeping design options flexible for as long as possible instead of choosing a single point solution upfront
65
Problem with traditional milestones (related to principle #5 - based milestones on objective evaluation of working systems)
Delays critical learning points until it's too late
- Centralizing requirements and design decisions in siloed functions that do not actually build the system.
- Forcing too-early design decisions and false-positive feasibility.
- Assuming a point solution exists and can be built correctly the first time. This ignores the variability inherent in the process and provides no legitimate outlet for it. Variability will find a way to express itself.
- Making up-front decisions creates large batches of requirements, code, and tests, and long queues. This leads to large-batch handoffs and delayed feedback.
66
Benefits of Cadence (related to principle #7)
- Converts unpredictable events into predictable ones and lowers cost
- Makes waiting times for new work predictable
- Supports regular planning and cross-functional coordination
- Limits batch sizes to single interval

- Occurs every Program Increment (PI)
- Acts as estimating buffer for meeting PI Objectives
91
Type of activities during IP Iteration
- Time for innovation and exploration, beyond the iterations dedicated to delivery
- Work on technical infrastructure, tooling, and other impediments to delivery
- Education to support continuous learning and improvement
- Cross training to develop skills in new domains, development languages, and systems
- Dedicated time for the I&A event, backlog refinement, including final prioritization of Features using Weighted Shortest Job First (WSJF), and PI planning
- Final integration of the solution, including verification and validation, if releasing on the PI boundary
- Final user acceptance testing and documentation, and any other readiness activities that are not feasible or economical to perform every iteration
