Performance engineering internal group(team) responsibility

Here is a draft of internal performance group(team) responsibility chart in my mind, so much things to do, we need to prioritize each section better to maximum its value :

Responsibility	Tasks	Role	Delivery
Capacity planning	1. Current user pattern/distribution 2. Gap analysis 3. Predict trend of usage 4. Top slow transactions 5. Top usage of transactions	QA lead, Performance QA(owner) PM, OPS(supportive) SDM, TL(consultant)	Access log analysis result RFP distribution pattern
Performance Environment Setup	1. Setup Performance environment 2. Data preparation 3. Server configuration	SCM/Dev (owner) Performance QA (supportive)	Testable performance environment
Performance test planning and design	1. Performance test strategy design 2. Performance testing scripts/scenario design 3. Keep performance test scripts/ load distribution update to date	Performance QA(owner) Performance Dev(supportive) SDM, TL, QA lead(consultant)	Performance test scripts/ scenarios
Code review and design inspection	1. code review and Performance inspection checklist	Performance Dev , TL(owner) Performance QA(supportive) Arch(consultant)	Code review retro
Performance testing Execution	1. User-story based performance test 2. Weekly performance test 3. Release performance testing 4. End-end performance test 5. Performance initiatives 6. Performance test report	Performance QA(owner) Performance Dev(supportive)	Performance test result report
Performance result analysis	1. Server log issues analysis 2. Performance test result analysis 3. Conclusion of performance Grade and suggestion of further investigation	Performance Dev(owner) Performance QA(supportive)	Identify any potential Performance bottlenecks Escalate Performance issues to the team
Performance improvement planning	1. making follow up plan for escalated performance issues	SDM, TL, QA lead(owner) Performance QA/Dev(supportive)	Create tech user stories for each performance issue Triage the priority of each performance user story
Performance tuning	1. Java back-end performance tuning 2. DB tuning 3. Front-end performance tuning 4. Performance Validation	SDM, TL, Dev (owner) Performance QA(supportive)	Tuning analysis summary Performance improvement comparison result Code review Check-in code into new release
Production Performance issues Follow up	1. Log performance issue in Rally 2. Server log analysis 3. Reproduce performance issue on local 4. Find the root cause of bottleneck	Performance Dev(owner) Performance QA(supportive)	Performance issue analysis result Reproduce suggestions
