QA-What were your roles and responsibilities and how was your time divided between tasks in a project?

Normally a test lead works on the project just the way the other team members do. Only 10 %( industry standard, might differ from project to project) of the time is spent on coordination activities.

You can further break this down into saying:

• 50%- Testing activities- depending on the stage the project is in, this might be test planning, design or execution
• 20%- review
• 10%- coordination
• 20%- client communication and delivery management
