Quality Management with Digital Tools: Why Switch to Digital?

Digital Quality Management in Industry: An Overview

The digital transformation of quality management represents a significant turning point for the manufacturing industry. While 65% of companies still rely on paper-based manual systems or basic Excel spreadsheets, the implementation of a digital quality management system offers unprecedented opportunities to optimize quality tracking, improve data accuracy, and facilitate decision-making. In the industrial quality sector, companies that have digitized their processes experience a 75% reduction in the time taken to process non-conformities. This article delves deeply into the advantages and implications of transitioning to digital in manufacturing quality management.

Current Challenges in Traditional Quality Management

The Issue with Manual Systems

Manual systems generate an average of 4.4 errors per 100 data entries, with key limitations including:

15% of paper forms are misplaced or misfiled
3.5 hours per week are lost searching for documents
25% of data entered contain transcription errors
40% of quality managers' time is spent on administrative tasks
Traceability takes an average of 4 times longer than with a digital system
Physical archiving costs approximately $2,500 per year for a manufacturing SME

The Specific Case of OEE/OEE in Industrial Quality

In the context of Overall Equipment Effectiveness (OEE), it is observed that:

Only 45% of companies systematically collect quality data
30% of quality data is not correlated with production data
The average time to identify a quality issue is 2.7 hours
60% of companies cannot calculate their OEE in real-time

The shift to a digital quality management system can address these fundamental issues.

Advantages of Digitization

Simplification of Quality Data Entry

Modern digital solutions enable:

An 82% reduction in data entry time
A 95% decrease in transcription errors

A 45% decrease in non-quality costs
Direct savings on archiving and document management costs

Implementing Digital Transformation

Quality Digitization Solutions

Available solutions include:

MES systems with integrated quality modules
Cloud platforms dedicated to quality
Mobile apps for data collection
Real-time visualization interfaces

Tools and Technologies for Digital Quality Management

Technical investment requires:

MES systems with integrated quality modules
Machine connectivity via various solutions: OPC-UA/MQTT protocols, IoT, or other communication protocols depending on existing infrastructure
An appropriate backup system (automatic for on-premise solutions, continuous for cloud solutions)

Transformation of Quality Processes

Successful implementation necessitates:

A deployment plan lasting 12 to 16 weeks
A 4-week pilot phase on a production line
Weekly checkpoints
Detailed technical documentation of processes
Backup and disaster recovery procedures

Optimizing Quality Processes

Automation vs. Manual Entry

Balancing automation and human intervention is crucial:

Automation Possible (80% of Cases):

Dimensional measurements via sensors, trained cameras, or CMM machines
Visual inspections through artificial vision
Automatic weighings
Barcode/QR code readings
Process data acquisition

Need for Manual Entry (20% of Cases):

Subjective evaluations (appearance, texture)
Sensory analyses
Expert validations
Qualitative comments
Complex decision-making

Analysis and Continuous Improvement

Digital tools allow for:

Real-time analysis with updates every 30 seconds
Automated daily, weekly, and monthly reports
Identification of trends over periods of 1 to 12 months
Full traceability achieved in less than 3 minutes

Performance and Digital Quality Indicators

Measuring Key Indicators

Digitization significantly improves KPIs:

A 65% reduction in non-conformity rates
A 45% decrease in non-quality costs
Reaction time to issues reduced by 75% (from 2.7 hours to 40 minutes)
A 35% increase in the effectiveness of corrective actions
A 25% improvement in First Time Right rates
A 50% reduction in customer complaints

Organizational Benefits

Measurable impact on the organization:

An 82% reduction in administrative errors
A gain of 15 hours per week for quality teams
A 60% increase in responsiveness to non-conformities
A 30% improvement in customer satisfaction

Conclusion

The digital transformation of quality in the manufacturing industry yields significant quantifiable gains. Implementing a digital quality management system typically results in a 65% reduction in non-conformities and a 40% improvement in operational efficiency.

Large manufacturing companies demonstrate that a balanced approach between automation and human expertise is key to success. The initial investment is more than compensated by an average ROI of 267% over 3 years. The user-friendliness of digital tools and their seamless integration into existing processes not only optimizes quality but also significantly enhances the overall performance of the manufacturing enterprise.
