Case Study: Readiness for a Modern ERP Conversion

Initial Situation

A manufacturing company was operating an ERP landscape with over a decade of accumulated custom code. A conversion path had not been decided, but the program deadline was already fixed in the executive board plan.

Challenge

Without a factual basis, two camps opposed each other: a new build versus converting the existing landscape. Neither position could be substantiated with hard numbers.

What OXORY Did

In a four-week readiness assessment, we analyzed the impact of core system modernization, compared conversion paths, and created a target sizing. This included a custom code analysis, an evaluation of interfaces, and a schedule model for each path.

Result

• Decision in favor of the brownfield path, substantiated by an effort and risk comparison
• Custom code scope reduced by **35%** (decommissioning of unused developments)
• Around **five months** of planning time saved by bringing the fundamental debate to an end

Applicable to

Organizations with a high share of custom developments facing a modernization decision that need a robust proposal for executive management.
