What is the role of a tester in the development process before the project implementation begins?

The role of a tester before starting the project implementation includes:

• Participating in requirements analysis and specifications to identify potential problems and ambiguities.
• Assisting in formulating acceptance criteria and test scenarios based on requirements.
• Planning testing: selecting appropriate types of testing, preparing test documentation.
• Risk assessment and preparing a testing strategy.

Thus, the tester helps ensure product quality from the very beginning, preventing errors and misunderstandings during the development process.
