Case Study: Readiness for Modern ERP Conversion

Background

A manufacturing company operated an ERP landscape with over a decade of accumulated custom code. A conversion path had not yet been decided, yet the program milestone was already locked in the board schedule.

Challenge

Without a solid factual foundation, two camps were in conflict: a greenfield rebuild versus conversion of the existing system. Neither position could be backed by hard numbers.

What OXORY Did

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

Results

• Decision in favor of the brownfield path, backed by effort and risk comparisons
• Custom code footprint reduced by **35%** (decommissioning unused developments)
• Around **five months** of planning time saved by putting an end to fundamental debates

Applicable to

Organizations with a high proportion of custom developments facing a modernization decision and needing a reliable business case for executive management.
