What pitfalls did the client face? 

The client encountered several challenges with their existing systems: 

Manual Processes


High reliance on manual data entry and task execution led to inefficiencies. 

Complexity


The complexity of the Liferay platform made it difficult for users to perform tasks without extensive knowledge. 

Limited Automation


Lack of automated tools for common tasks resulted in higher operational costs and time consumption. 

User Experience


The existing user interface was not intuitive, leading to user frustration and low adoption rates. 

What pitfalls did the client face? 

1) 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

2) Data Quality and Standardization  

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

3) Regulatory Compliance

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

4) Staff Resistance

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