# Business-as-Code Implementation

## Overview

The `business-as-code` package provides primitives for expressing business logic and processes as code. It includes comprehensive TypeScript types and functions for defining:

- Business entities and organizational structures
- Vision statements and strategic goals
- Products and services with pricing models
- Business processes and workflows
- Key Performance Indicators (KPIs)
- Objectives and Key Results (OKRs)
- Financial metrics and calculations
- Business operations helper ($)

## Implementation Details

### Core Types (types.ts)

Defines comprehensive TypeScript interfaces for:
- `BusinessDefinition` - Complete business entity structure
- `GoalDefinition` - Strategic and operational goals
- `ProductDefinition` - Product specifications with roadmap
- `ServiceDefinition` - Service offerings with SLA
- `ProcessDefinition` - Business process steps and metrics
- `WorkflowDefinition` - Automated workflow sequences
- `KPIDefinition` - Key performance indicators
- `OKRDefinition` - Objectives and key results
- `FinancialMetrics` - Financial statements and calculations
- `BusinessOperations` - $ helper interface

### Main Functions

1. **Business()** - Define business entity
   - Organizational structure with departments and teams
   - Mission, values, and metadata
   - Budget and team size tracking

2. **Vision()** - Define vision statement
   - Strategic direction
   - Success indicators
   - Timeframe tracking

3. **Goals()** - Define and track goals
   - Goal categories (strategic, operational, financial, etc.)
   - Progress tracking (0-100%)
   - Dependency management
   - Status tracking (not-started, in-progress, at-risk, completed)

4. **Product()** - Define products
   - Pricing models (one-time, subscription, usage-based, freemium, tiered)
   - Cost of goods sold (COGS)
   - Product roadmap
   - Gross margin calculations

5. **Service()** - Define services
   - Pricing models (hourly, fixed, retainer, value-based)
   - Service level agreements (SLA)
   - Delivery time estimation

6. **Process()** - Define business processes
   - Process steps with automation levels
   - Duration calculations
   - Automation percentage tracking
   - Process metrics

7. **Workflow()** - Define automated workflows
   - Event, schedule, webhook, and manual triggers
   - Action sequences (send, create, update, delete, notify, call, wait)
   - Conditional execution
   - Template variable substitution

8. **kpis()** - Track key performance indicators
   - Categories (financial, customer, operations, people, growth)
   - Target vs. current value tracking
   - Achievement calculations
   - Health score aggregation

9. **okrs()** - Define OKRs
   - Objective statements
   - Key results with progress tracking
   - Confidence scoring
   - Status management

10. **financials()** - Calculate financial metrics
    - Gross profit and margin
    - Operating income and margin
    - Net income and margin
    - EBITDA and margin
    - Burn rate and runway
    - Customer acquisition cost (CAC)
    - Customer lifetime value (LTV)
    - Return on investment (ROI)

11. **$** - Business operations helper
    - Currency formatting
    - Percentage calculations
    - Growth rate calculations
    - Margin calculations
    - ROI calculations
    - LTV/CAC calculations
    - Burn rate and runway
    - Business context management

## Key Features

### Type Safety
- Comprehensive TypeScript types
- Full IntelliSense support
- Compile-time validation

### Validation
- Input validation for all functions
- Error messages for invalid data
- Circular dependency detection (goals)
- Constraint checking (budgets, progress, etc.)

### Calculations
- Financial metrics (margins, ROI, etc.)
- Progress tracking (goals, OKRs)
- Time-based calculations (duration, runway)
- Achievement percentages

### Flexibility
- Optional fields with sensible defaults
- Metadata support on all entities
- Extensible interfaces
- Multiple pricing models

## Test Coverage

27 comprehensive tests covering:
- Business entity creation and validation
- Vision statement validation
- Goal progress tracking and dependencies
- Product gross margin calculations
- Service pricing models
- Process automation tracking
- Workflow trigger validation
- KPI target achievement
- OKR progress calculations
- Financial metric calculations
- $ helper utility functions

All tests passing ✓

## Build Output

Successfully compiled to:
- JavaScript (ES modules)
- TypeScript declarations (.d.ts)
- Source maps (.js.map, .d.ts.map)

Total: 52 files in dist/ directory

## Dependencies

- `ai-functions` (workspace:*) - For AI integrations

## Next Steps

The package is fully implemented and ready for use. Potential enhancements:

1. Add more financial calculations (DCF, NPV, IRR)
2. Add forecasting functions
3. Add data visualization helpers
4. Add export functions (CSV, Excel, PDF)
5. Add time-series analysis for KPIs and financials
6. Add goal/OKR templates for common scenarios
7. Integration with actual data sources
8. Reporting and dashboard generation

## Usage Example

See `examples/basic-usage.ts` for a complete working example demonstrating all features.

```typescript
import { Business, Goals, Product, kpis, okrs, financials, $ } from 'business-as-code'

// Define business
const company = Business({ name: 'Acme Corp', ... })

// Track goals
const goals = Goals([...])

// Define products
const product = Product({ name: 'Widget Pro', price: 99, ... })

// Track KPIs
const kpiList = kpis([...])

// Define OKRs
const okrList = okrs([...])

// Calculate financials
const metrics = financials({ revenue: 1000000, ... })

// Use $ helper
console.log($.format(1234.56)) // "$1,234.56"
console.log($.growth(120, 100)) // 20
```
