What pitfalls did the client face? 

Legacy System Integration

 

Existing systems were not designed for AI integration. Historical data was stored in various formats and locations. Manual processes were deeply embedded in operations.

Data Quality & Standardization

 

Inconsistent data formats across different sources. Missing or incomplete historical data. Lack of standardized documentation processes.

Staff Resistance

 

Concerns about job security. Reluctance to adopt new technologies. Learning curve for new systems

Regulatory Compliance

 

Need for explainable AI decisions. Ensuring fair lending practices. Meeting data privacy requirements.
