Performance Test Analyst

Responsibilities:

• Explain the performance test methodology to all the stakeholders.
• Provide Guidance to the application team /stakeholder to complete the performance testing approach/requirements document.
• Provide initial assessment of performance testing needs (whether application is right candidate for performance testing )
• Document all the performance testing requirements, scope & objectives.
• Provide the estimates on various phases of Performance testing.
