EXAM PREPARATION PACK 2026 KEY
CONCEPTS AND REVISION NOTES
◉ Transparency.
Answer: visualize relevant work, admits mistakes, support others.
◉ SAFe House of Lean.
Answer: Illustrates the goal of delivering VALUE through the pillars
of Respect for people and culture, Flow, Innovation, and Relentless
improvement. LEADERSHIP provides the foundation on which
everything else stands.
◉ Respect for people and culture.
Answer: House of Lean. Generative Culture; People do all the work;
Customer is whomever consumes your work; Build long-term
partnerships based on trust; To change the Culture, Change the
Organization.
◉ Flow.
Answer: House of Lean. Optimize sustainable Value delivery; Build in
Quality; Understand, exploit & manage variability; Move from
Projects to Products.
,◉ Innovation.
Answer: House of Lean. Innovative people, provide time & space for
Innovation, Go see; Experimentation & Feedback; Innovation
riptides; Pivot without mercy or guilt.
◉ Relentless improvement.
Answer: House of Lean. Constant sense of danger; Optimize the
whole; problem-solving culture; Base improvements on facts; Reflect
at Key Milestones.
◉ Value.
Answer: House of Lean. Achieve the shortest sustainable lead time
with The best Quality & Value to People & Society; high Morale,
Safety and Customer Delight.
◉ Leadership.
Answer: House of Lean.Lead by example; Adopt growth mindset
(why do it this way?); Exemplify values & principles of Lean-Agile &
SAFe; Develop people; Lead the change; Foster psychological safety.
◉ Lean-Agile Principles.
Answer: SAFe is based on ten immutable, underlying Lean-Agile
principles which inspire and inform the roles and practices of SAFe:
,*Take an economic view; *Apply systems thinking; *Assume
variability; *Build incrementally with fast, integrated learning cycles;
*Base milestones on objective evaluation of working systems;
*Visualize & limit WIP, reduce batch sizes, manage Q lengths; *Apply
cadence, sync with x-domain planning; *Unlock intrinsic motivation
of knowledge workers; * Decentralize decision-making; *Organize
around value.
◉ Take an Economic view.
Answer: Lean-Agile Prin. * Deliver Value early & often. &
incrementally; Solution economic trade-offs.: * Sequence jobs for
maximum benefit; * Do not consider Sunk Costs; * Make economic
choices continuously (pivot relentlessly); *Empower local decision
making; * Quantify the Cost of Delay.
◉ Apply Systems Thinking.
Answer: Lean-Agile Prin. ATTRIBUTES: * Optimizing a component
does not optimize the system; * a higher-level of understanding &
Arch is required; *System value passed through its interconnections;
* System can evolve no faster than its slowest integration point.
◉ Optimize Full Value Stream.
Answer: Lean-Agile Prin., Systems Thinking. * Reducing Delays in
Value Stream is fastest way to reduce time to market.
, ◉ Assume Variability; preserve options.
Answer: Lean-Agile Prin. *Requirements must be flexible to make
economic designs choices. *Design must be flexible to support
changing requirements. *Preservation of options improves economic
options.. Apply a set-based approach.
◉ Build incrementally with fast, integrated learning cycles.
Answer: Lean-Agile Prin. * Apply fast learning cycles - shorter the
cycle, faster the learning. PDCA (Plan, Do, Check, Adjust). Facilitated
by small batch cycles. * Apply fast learning cycles. Integration points
control product development. Dev proceeds no faster than the
slowest learning loop. *Integration points reduce risk.
◉ Base milestones on objective evaluation of working systems.
Answer: Lean-Agile Prin. 1. Apply Objective Milestones: PI system
demos are orchestrated to deliver objective progress, product, and
process Metrics. 2. Iterate to optimum solution (Objective
Milestones). *Problems with Phase-gate milestones: early design
decisions, assume solution can be built correctly first time, create
huge batches and long queues. *Requirements & decisions too early,
adjustments too late & costly as new facts emerge.
◉ Visualize and limit WIP, reduce batch sizes, manage Q lengths.
Answer: Lean-Agile Prin. *Reduce batch sizes for higher
predictability, accelerated feedback, - less rework, lower cost. Most
important is Handoff Batch. *Find optimal batch size. Higher
