Lean Six Sigma Analysis of Employment Verification Issues at Dumfries and Galloway Council

CHECKS to ensure people have a legal right to work here are not always being carried out by Dumfries and Galloway Council.

Despite being the largest employer in the region, with around 6500 staff members, an internal audit found that the local authority sometimes slipped up when recruiting new workers.

Let me analyze this situation using Lean Six Sigma methodology, which focuses on process improvement through waste elimination and defect reduction.

DMAIC Framework Analysis

Define

- **Problem Statement**: Dumfries and Galloway Council is experiencing failures in employment verification processes, creating legal compliance risks and potential financial penalties of up to £60,000 per illegal worker.

- **Scope**: Employee verification process from recruitment through documentation storage.

- **Critical to Quality (CTQ)**: 100% compliance with UK right-to-work verification requirements.

Measure

- **Current Performance**: 

  - 10% defect rate (3 out of 30 samples) where incorrect documentation was accepted

  - 70% of recruiting managers lack required training

  - Unknown number of missing historical verification documents

Analyze

- **Root Causes**:

  1. **Process Variation**: Inconsistent application of verification standards

  2. **Knowledge Deficit**: Managers unfamiliar with proper documentation requirements

  3. **Training Gap**: 70% of managers haven't completed mandatory training

  4. **No Refresher Requirements**: No cyclical training for managers who recruit infrequently

  5. **Documentation System Failures**: Inadequate storage/retrieval system for verification documents

  6. **Lack of Process Controls**: No verification checkpoints to catch errors

Improve

- **Recommended Solutions**:

  1. **Standardized Work**: Create simple, visual process checklists for verification (poka-yoke)

  2. **Training Kaizen**: Implement regular mandatory training cycles (not just one-time)

  3. **Visual Management**: Develop clear visual guides showing acceptable vs. unacceptable documents

  4. **Process Automation**: Implement digital document verification with built-in error checking

  5. **Pull System**: Create verification triggers that prevent hiring completion without proper documentation

  6. **Error-Proofing**: Add second-level verification for all right-to-work documents

Control

- **Sustainability Plan**:

  1. **Process Audits**: Regular random sampling of verification documents (with defined control limits)

  2. **Dashboard Metrics**: Monthly tracking of verification compliance rates

  3. **Standard Work Audits**: Regular observation of managers performing verification process

  4. **Training Compliance Tracking**: System alerts for managers with expired or missing training

  5. **PDCA Cycles**: Quarterly reviews to identify and address new process variations

Value Stream Analysis

The current process contains significant muda (waste):

- **Defects**: Incorrect document acceptance

- **Skills**: Underutilized staff capabilities due to lack of training

- **Waiting**: Potential delays from document retrieval issues

- **Non-Utilized Talent**: Managers operating without proper knowledge

This analysis suggests the council would benefit from standardizing the verification process, implementing error-proofing mechanisms, and creating a robust control system to ensure sustainability of improvements. The goal should be to achieve Six Sigma quality levels (3.4 defects per million opportunities) in verification compliance.
