Implementation Challenges and Solutions

The project faced several significant challenges:

Legacy System Integration

Challenge: NDS's 15-year-old ERP system had limited integration capabilities and customized business logic. Solution: We developed a custom middleware layer with extensive data validation and error handling, enabling reliable bidirectional communication while preserving critical customizations.

Change Management Resistance

Challenge: Long-tenured warehouse staff expressed concern about job security and learning new technologies. Solution: We implemented a comprehensive change management program including:

• Early involvement of floor supervisors in system design
• Hands-on training programs adapted to various learning styles
• Creation of "automation champion" roles for respected team members
• Clear communication about new career paths in the automated environment

Physical Space Constraints

Challenge: Existing warehouse layouts were not designed for automation systems. Solution: We developed a phased implementation approach that allowed for:

• Sectional renovation without operational shutdown
• Modular automation components adaptable to space constraints
• Weekend installations for critical infrastructure components
• Temporary workflow adjustments during transition periods

Data Quality Issues

Challenge: Historical inventory and location data contained significant inaccuracies. Solution: We created a data remediation workstream that included:

• Automated data cleansing algorithms for common issues
• Physical inventory verification of high-value and high-volume SKUs
• Dual-running period with both systems to validate data accuracy
• Progressive data migration approach prioritizing critical elements

Key Learnings and Best Practices

The project yielded valuable insights applicable to similar automation initiatives:

Phased Implementation Approach
