aced with soaring inventory levels and strained service performance across its global operations, Amkor Technology needed more than a system overhaul—it needed a smarter way to run its business. By partnering with Reveal and deploying the oVo® methodology, Amkor re-engineered its use of SAP®, restored trust in data, and embedded new supply chain disciplines across five regions. The results: reduced inventory, improved service levels, higher process efficiency, and lasting operational control.

The Challenge

Despite being a global leader in semiconductor packaging and test services, Amkor Technology struggled with critical inefficiencies:

• Excess inventory clogged the supply network, tying up working capital
• Service levels suffered from manual workarounds and inconsistent processes
• SAP® tools like MRP were underutilized, sidelined by legacy customizations
• Master data was disorganized and lacked governance
• Business decisions were delayed by unreliable data and fragmented visibility

The complexity of a global supply chain, paired with low trust in their SAP system, threatened operational performance and profitability.

The Decision

Amkor chose Reveal for their proven ability to transform SAP from a cost burden into a business asset. With Reveal’s oVo® methodology, the focus would be on business-led change—not just technical fixes. This meant addressing user behavior, reintroducing SAP best practices, and building a sustainable model for governance and performance.

The Transformation

The partnership centered around a phased deployment of oVo® across five global regions. Key actions included:

• Re-implementing standard SAP® processes, particularly MRP, to automate manual tasks
• Educating users and leadership to rebuild trust in SAP data
• Establishing daily disciplines and corporate policies to embed change
• Centralizing and governing master data to support global operations
• Enhancing visibility across the supply chain to support proactive decision-making

Importantly, the project prioritized people and processes as much as the technology—ensuring lasting adoption and business ownership.

The Results

Amkor achieved measurable, strategic business outcomes:

• Inventory Reduction: Target reductions achieved across multiple regions
• Service Level Improvement: Performance exceeded target benchmarks
• Process Efficiency: Exception messages were significantly reduced
• Data Maturity: Improved accuracy, trust, and alignment across functions
• Executive Visibility: Real-time insights enabled faster, better decisions
• Sustainability: Governance structures and business rules embedded globally

For Amkor, success wasn’t just about reducing inventory—it was about gaining control, unlocking SAP’s full potential, and building a supply chain ready for the future. If your SAP system isn’t delivering measurable business value, it’s time to bridge the gap between what it can do and how your teams use it.
