Who determines the parameters of load testing?

Load testing parameters are usually determined collaboratively by a team including:

• System Analyst: formulates load requirements based on business goals and expected user behavior.
• Technical specialists (developers, load testing engineers): assess the technical capabilities of the system and help define realistic parameters.
• Customer or business representatives: set the target performance indicators.

Ultimately, parameters (such as the number of concurrent users, types of scenarios, test duration) are formed based on analysis of requirements, system architecture, and testing objectives.
