# KPI Implementation Workflow

Implementing KPIs in Pay-i follows this recommended workflow:

## 1. Define KPIs During Use Case Planning

Define your KPIs as part of your use case design process, before implementation begins:

```python
# Create KPI definitions for your use case type
client.use_cases.definitions.kpis.create(
    use_case_name="Content-Generator",
    kpi_name="Clickthrough Rate",
    description="Measures user engagement with generated content",
    kpi_type="boolean",
    goal=0.05  # 5% target
)
```

## 2. Instrument Your Application

Add instrumentation at key points in your application to record KPI values:

```python
# When a user interacts with generated content
if user_clicked_on_content:
    client.use_cases.kpis.create(
        kpi_name="Clickthrough Rate",
        use_case_id=content_generation_id,
        score=1.0  # True for clicked
    )
else:
    client.use_cases.kpis.create(
        kpi_name="Clickthrough Rate",
        use_case_id=content_generation_id,
        score=0.0  # False for not clicked
    )
```

## 3. Review KPI Data Regularly

Schedule regular reviews of your KPI data in the Pay-i dashboard:

- Daily for operational metrics
- Weekly for tactical improvements
- Monthly for strategic decision-making

## 4. Refine KPIs Based on Learnings

As you learn more about your application's performance, refine your KPIs:

- Adjust thresholds to reflect achievable targets
- Add new KPIs to measure emerging aspects
- Retire KPIs that no longer provide value

# Tracking Improvement Across Versions

One of the most powerful uses of KPIs is tracking improvement across different versions of your use case:

### Consistent KPI Names

Maintain the same KPI names across all versions of your application to enable direct comparison:

```python
# For version 1
client.use_cases.definitions.kpis.create(
    use_case_name="Content-Generator-v1",
    kpi_name="Clickthrough Rate",
    description="Measures user engagement with generated content",
    kpi_type="boolean",
    goal=0.05
)

# For version 2 (same KPI name, higher goal)
client.use_cases.definitions.kpis.create(
    use_case_name="Content-Generator-v2",
    kpi_name="Clickthrough Rate",
    description="Measures user engagement with generated content",
    kpi_type="boolean",
    goal=0.07  # Increased target
)
```

## Version-Specific Goals

Set progressively more ambitious goals for newer versions of your application:

1. **Version 1**: Focus on basic functionality and adoption
2. **Version 2**: Optimize for core performance metrics
3. **Version 3+**: Maximize business impact and ROI

## Version Comparison Analysis

In the Pay-i dashboard, compare KPIs across versions to:

- Validate improvements from new features
- Identify regressions that need addressing
- Quantify the ROI of development efforts

## A/B Testing with KPIs

KPIs provide an ideal framework for conducting A/B tests of different GenAI implementations:

### KPI-Based A/B Testing Workflow

1. **Define Test Versions**: Create distinct use case types for each variant
2. **Establish Identical KPIs**: Define the same KPIs across all variants
3. **Distribute Traffic**: Send users to different variants randomly
4. **Measure Performance**: Compare KPI values between variants
5. **Analyze Results**: Determine which variant performs best

## Example Implementation

```python
# Define identical KPIs for both test variants
for variant in ["Content-Generator-A", "Content-Generator-B"]:
    client.use_cases.definitions.kpis.create(
        use_case_name=variant,
        kpi_name="Conversion Rate",
        description="Percentage of users who make a purchase",
        kpi_type="boolean",
        goal=0.02  # 2% target
    )

# In application code, record KPIs for the assigned variant
variant = get_assigned_variant(user_id)  # Your A/B test assignment logic
use_case = client.use_cases.create(use_case_name=variant)

# Later, record conversion
if user_purchased:
    client.use_cases.kpis.create(
        kpi_name="Conversion Rate",
        use_case_id=use_case.use_case_id,
        score=1.0  # True for converted
    )
```

# Long-Term KPI Maintenance

KPIs should evolve with your application and business needs:

### Regular KPI Review

Schedule quarterly reviews of your KPI framework to:

1. **Assess Relevance**: Determine if existing KPIs still align with business goals
2. **Measure Goal Appropriateness**: Check if goals are still challenging but achievable
3. **Identify Gaps**: Determine if new KPIs are needed to measure emerging concerns
4. **Prune Redundancies**: Remove KPIs that provide duplicate insights

## KPI Governance

Establish clear governance for your KPIs:

- **Documentation**: Maintain detailed documentation of KPI definitions and calculations
- **Ownership**: Assign clear ownership for each KPI
- **Change Management**: Define a process for proposing and approving KPI changes
- **Historical Tracking**: Preserve historical KPI data for long-term trend analysis

# Value-Focused KPIs

The most effective KPIs directly connect to business value:

### Time and Cost Savings

Implement consistent time and cost saving KPIs across all use case types:

```python
# Define time savings KPI for all use case types
for use_case_type in ["Chatbot", "Content-Generator", "Document-Processor"]:
    client.use_cases.definitions.kpis.create(
        use_case_name=use_case_type,
        kpi_name="Time Saved",
        description="Minutes saved compared to manual process",
        kpi_type="number",
        goal=2.0  # 2 minutes target
    )
```

## Revenue Impact

Track direct revenue impact whenever possible:

```python
client.use_cases.definitions.kpis.create(
    use_case_name="Product-Recommender",
    kpi_name="Revenue Generated",
    description="Additional revenue from AI recommendations",
    kpi_type="number",
    goal=15.0  # $15 per recommendation
)
```

## Customer Experience

Balance efficiency metrics with customer experience measures:

```python
client.use_cases.definitions.kpis.create(
    use_case_name="Chatbot",
    kpi_name="Customer Satisfaction",
    description="User rating of interaction quality",
    kpi_type="likert5",
    goal=4.2  # 4.2/5 target
)
```
