Case Study: Simplifying a Legacy Integration Landscape

Initial Situation

A retail enterprise operated more than 120 point-to-point interfaces between ERP, e-commerce shop, warehouse, and marketplaces. Documentation only existed in fragments, and crucial knowledge was confined to individual experts.

Challenge

Every change triggered ripple effects elsewhere, and identifying the root cause of an incident routinely took longer than fixing it.

What OXORY Did

We built a comprehensive interface inventory, designed a target integration architecture, and defined an API-led connectivity pattern — including a sound middleware recommendation and governance framework for new interfaces.

Result

• **40%** fewer interfaces to maintain through consolidation and decommissioning
• Incident resolution time **cut in half** thanks to traceable error paths
• New connections follow a standardized reference pattern instead of ad-hoc custom solutions

Applicable To

Landscapes that have grown organically around isolated projects over years, where every change is perceived as a high risk.
