Erp Integration Analysis

Analyze ERP system integration for construction data flows. Map and optimize data flows between ERP modules

# ERP Integration Analysis

## Overview

Based on DDC methodology (Chapter 1.2), this skill analyzes ERP system integration patterns in construction organizations, mapping data flows between modules and identifying optimization opportunities.
