## 🔍 Use Case Analysis & Gap Discovery

**Analysis Based On**: Issue #63 use case brainstorming
**Method**: Practical examples with real-world business scenarios
**Examples Created**: Invoice templates, design patterns, compliance documents

### **MarkiTect Foundation Strengths** ✅
- **Document Structure & Metadata**: Complete frontmatter/contentmatter/tailmatter support
- **Quality Assurance**: QA checklists, editorial workflows, validation systems
- **Analysis Capabilities**: AST parsing, schema generation, comprehensive statistics
- **CLI Maturity**: 740 passing tests, robust command interface
- **Multi-format Support**: YAML/JSON/TOML parsing, flexible output formats

### **Critical Gaps Identified** 🎯

#### **Gap 1: Template Engine & Dynamic Generation**
**Problem**: Cannot generate documents from templates + data
**Business Impact**: Unable to create invoices, letters, reports from templates
**Example**: `{{customer.name}}` stays literal, no rendering to "Acme Corporation"

#### **Gap 2: Calculation & Business Logic**
**Problem**: No mathematical operations or formula evaluation
**Business Impact**: Cannot compute totals, taxes, derived values
**Example**: Cannot calculate `{{sum line_items 'total'}}` or `{{multiply subtotal tax_rate}}`

#### **Gap 3: Batch Processing & Automation**
**Problem**: No multi-document operations or workflow automation
**Business Impact**: Cannot scale to mass generation, batch validation
**Example**: Cannot process 100 invoices from customer database

#### **Gap 4: External Data Integration**
**Problem**: No connectivity to databases, APIs, external sources
**Business Impact**: Manual data preparation, no business system integration
**Example**: Cannot import customer data from CRM or ERP systems

#### **Gap 5: Cross-Document Relationships**
**Problem**: No document linking or reference validation
**Business Impact**: Cannot maintain document hierarchies or dependencies
**Example**: Cannot validate that referenced specifications actually exist

#### **Gap 6: Advanced Output Formats**
**Problem**: Limited professional output capabilities
**Business Impact**: Cannot generate PDFs, styled documents for business use
**Example**: Cannot create professional invoices or compliance reports
