In quality management, what is the purpose of a 'control chart'?

A PM discovers that 30% of newly shipped features have bugs found by customers rather than QA. What does this indicate?
Answer: High defect escape rate
Defect escape rate measures how many defects pass through internal quality checks and reach customers, with a high rate signaling weak QA processes.
Which technique involves systematically releasing a product to a small percentage of users first to limit quality risk?
Answer: Canary release
A canary release deploys a new version to a small subset of users first, allowing teams to detect quality issues before full rollout.
What is 'technical debt' in the context of product quality?
Answer: Shortcuts taken in development that increase future maintenance cost
Technical debt refers to the implied future rework caused by choosing expedient solutions now instead of better, more time-consuming approaches.
A PM wants to ensure a feature works correctly under extreme load before launch. Which type of testing is MOST appropriate?
