Ramp-up
Ramp-up is the gradual increase of workload or virtual users during a performance test until the desired load level is reached.
“A technique for increasing the load on a system in a measurable and controlled way.”

Gradually increasing load simulates realistic user growth and prevents unrealistic spikes that could distort test results.
Controlled increase: Users are added over time.
Realistic simulation: Better reflects production usage.
Performance measurement: Helps identify capacity limits.
Real World Example
A regulated product team is preparing a release where Ramp-up appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Ramp-up as interchangeable with nearby ISTQB terms. That makes test scope blurry and can lead to weak evidence for the release decision.
The tester anchors the discussion in the official definition, asks where the concept appears in the product, and designs examples that show the difference between Ramp-up and similar ideas.
The page becomes useful in practice because Ramp-up is connected to a specific testing decision, not memorized as a detached definition.
