# PERF05-BP03 - Define a process to improve workload performance

Best practice: PERF05-BP03
Pillar: Performance Efficiency
Source: https://wellarchitected.cloudvisor.eu/docs/performance-efficiency/perf05-bp03.html

## Implementation Guidance

"Define a process to improve workload performance" should be delivered as a standard operating capability with explicit scope, controls, and validation checkpoints. Embed it into day-to-day engineering and operations workflows.

For the question "How do you monitor your resources to ensure they are performing?", define measurable outcomes, assign owners, and review execution regularly. Integrate this practice into delivery and operations processes so improvements persist as workloads and requirements evolve.

### Key Steps

1. **Define implementation scope and outcomes**:
   - Set explicit success criteria for "Define a process to improve workload performance"
   - Identify dependencies, prerequisites, and sequencing constraints
   - Assign accountable owners for execution and maintenance

2. **Implement with standards and validation**:
   - Use reusable templates and runbooks for consistent execution
   - Validate implementation with tests, checks, or controlled rollouts
   - Capture telemetry to confirm adoption and effectiveness

3. **Operate and iterate**:
   - Review outcomes against KPIs on a recurring schedule
   - Fix recurring failure modes and process bottlenecks
   - Update implementation guidance based on operational learning

## Risk / Impact

**Level of risk if not implemented**: Medium

**Impact**: Without this best practice, workloads typically accumulate inefficiencies and execution drift that increase failure probability over time. Problems often surface during traffic spikes, major releases, or dependency failures.

**Benefits of implementation**:
- More predictable operational and engineering outcomes
- Better alignment between architecture decisions and business goals
- Continuous improvement through measurable feedback loops
