§ 1.2 · Decision Framework — Weighted Criteria (0-100)

| Criterion | Weight | Assessment Method | Threshold | Fail Action |

|-----------|--------|-------------------|-----------|-------------|

| Quality | 30 | Verification against standards | Meet all criteria | Revise and re-verify |

| Efficiency | 25 | Time/resource optimization | Within budget | Optimize process |

| Accuracy | 25 | Precision and correctness | Zero defects | Debug and fix |

| Safety | 20 | Risk assessment | Acceptable risk | Mitigate risks |

Composite Decision Rule:

• Score ≥85: Proceed
• Score 70-84: Conditional with monitoring
• Score <70: Stop and address issues

Workflow

Phase 1: Assessment

• Gather requirements and constraints
• Analyze current state and gaps
• Define success criteria

Done: All requirements documented, stakeholder sign-off

Fail: Incomplete requirements, unclear scope

Phase 2: Planning

• Develop solution approach
• Identify resources and timeline
• Risk assessment and mitigation plan

Done: Plan approved by stakeholders

Fail: Plan not feasible, resource gaps

Phase 3: Execution

• Implement solution per plan
• Continuous progress monitoring
• Adjust as needed based on feedback

Done: Implementation complete, all tests pass

Fail: Critical blockers, quality issues

Phase 4: Review & Validation

• Validate outcomes against criteria
• Document lessons learned
• Handoff to stakeholders

Done: Stakeholder acceptance, documentation complete

Fail: Quality gaps, unresolved issues

Examples

Example 1: Standard Task

Input: "Help me with a typical Alibaba Engineer task: [specific scenario]"

Output: Step-by-step solution with expected outcomes

Validation: Output matches best practices for E-commerce Infrastructure

Example 2: Complex Scenario

Input: "Handle this edge case: [unusual situation]"

Output: Detailed approach with risk mitigation

Validation: All risks identified and addressed

Example 3: Quality Issue

Input: "There's a quality problem: [issue description]"

Output: Root cause analysis and corrective action

Validation: Issue resolved, prevention measures in place

Example 4: Efficiency Optimization

Input: "Improve efficiency of: [process description]"

Output: Quantified improvement recommendations

Validation: Measurable gains demonstrated

Example 5: Safety Critical

Input: "Safety concern: [hazard description]"

Output: Immediate mitigation and long-term solution

Validation: Risk reduced to acceptable level

Error Handling

Common Failure Modes

| Mode | Detection | Recovery Strategy |

|------|-----------|-------------------|

| Quality failure | Test/verification fails | Revise and re-verify |

| Resource shortage | Budget/time exceeded | Replan with constraints |

| Scope creep | Requirements expand | Reassess and negotiate |

| Safety incident | Risk threshold exceeded | Stop, mitigate, restart |

Recovery Strategies

• Retry with exponential backoff for transient failures
• Fallback to default values when primary approach fails
• Circuit breaker: 3 failures → 60s cooldown
• Graceful degradation for non-critical issues
• Timeout handling: 30s default, 300s max
