Product Quality, Continuous Integration, Testing, and Continuous Improvement
Delivery questions test definition of done, verification, validation, CI, exploratory testing, usability, and sustained improvement.
How to study for PMI-ACP
Use the PMI-ACP ECO as the map: build agile mindset and leadership judgment, then practice product and delivery scenarios under full-exam pacing.
Core concepts
Concept 1
Definition of done creates a shared quality baseline; acceptance criteria add item-specific product behavior.
Exam cue: Match scripted, exploratory, usability, performance, security, accessibility, and contract tests to the risk being examined.
Concept 2
Verification asks whether the product was built correctly; validation asks whether it solves the right user problem.
Exam cue: Treat flaky or slow pipelines as feedback-system problems rather than normalizing ignored failures.
Concept 3
Continuous integration combines frequent small merges with fast, trustworthy automated feedback.
Exam cue: Use baselines, hypotheses, guardrails, control limits, and review points for continuous-improvement experiments.
Risk pitfalls and guardrails
Weakening done at iteration end to count unfinished quality work as complete.
Guardrail: Avoid command-and-control shortcuts, ceremony compliance without outcomes, unbounded WIP, late feedback, and choices that trade away quality, safety, privacy, or required governance.
Assuming high code coverage or requirements conformance proves customer usefulness.
Guardrail: Avoid command-and-control shortcuts, ceremony compliance without outcomes, unbounded WIP, late feedback, and choices that trade away quality, safety, privacy, or required governance.
Reacting to every normal fluctuation or scaling one local process improvement without context testing.

Memory anchors
Definition Of Done
Definition of done states the quality conditions required before work is complete.
Verification
Verification checks whether the product was built according to requirements or standards.
Validation
Validation checks whether the product solves the intended customer or user problem.
Continuous Integration
Continuous integration frequently merges and tests work to expose defects early.
Exploratory Testing
Exploratory testing uses investigation and learning to find unexpected product risks.
Usability Testing
Usability testing checks whether real users can complete intended tasks effectively.
Continuous Improvement
Continuous improvement uses evidence to make product, process, and people systems better.
Control Limit
A control limit helps distinguish normal process variation from a signal that needs attention.
Test Charter
A test charter gives exploratory testing a mission, risk focus, timebox, and evidence goal without scripting every step.
Contract Test
A contract test verifies that services honor a shared interface and catches boundary changes early.
Flaky Test
A flaky test passes and fails without a relevant product change, weakening trust in automated feedback.
Specification Limit
A specification limit expresses required performance, while a control limit describes observed process variation.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
