Quality & Test Engineering
Building confidence in product quality through effective engineering and testing
Quality is strongest when it is engineered into the product and process rather than inspected at the end.
Sable Logic provides quality and test engineering solutions that help manufacturers understand product performance, strengthen production controls and establish reliable methods of verification and validation.
Our approach brings together engineering, measurement, testing, manufacturing and data to ensure that quality decisions are based on meaningful technical evidence.
From test strategy and validation through process capability, failure investigation and production controls, we help customers improve confidence in both the product and the process used to manufacture it.
Quality Begins With the Requirement
Reliable quality decisions start with a clear understanding of what the product or process must achieve.
A test result only has value if the requirement behind it is understood, the test method is appropriate and the measurement system is capable of distinguishing acceptable from unacceptable performance.
Sable Logic works with customers to connect technical requirements with practical verification, validation and production controls.
Depending on the application, this may involve:
- Product and process requirements
- Critical quality characteristics
- Acceptance criteria
- Test coverage
- Measurement capability
- Verification and validation
- Process controls
- Traceability
- Data and evidence
- Risk and failure modes
The objective is to ensure that quality controls are technically meaningful and aligned with the performance expected from the product.
Test Strategy & Coverage
Testing the characteristics that matter
More testing does not automatically mean better quality.
The right test strategy identifies the characteristics that are critical to product performance and determines how, when and where they should be verified.
Sable Logic can support the development and improvement of production and validation test strategies, including:
- Test requirement definition
- Identification of critical parameters
- Test coverage assessment
- Test sequence development
- Acceptance criteria
- Pass/fail logic
- Test-limit definition
- Production versus laboratory testing
- Automated versus manual test selection
- Risk-based testing
- Data and traceability requirements
A well-designed test strategy reduces unnecessary testing while improving confidence that significant failures will be detected.
Verification & Validation
Demonstrating that the product and process perform as intended
Verification and validation provide structured evidence that requirements have been met.
Sable Logic can support verification and validation activities across product development, industrialisation, manufacturing and system implementation.
This may include:
- Verification planning
- Validation planning
- Requirements traceability
- Test method development
- Test protocol development
- Acceptance criteria
- Test execution support
- Data analysis
- Result interpretation
- Technical reporting
- Design or process change validation
- Equipment and system validation
The objective is to establish clear, objective evidence rather than relying on assumption or informal confirmation.
Production Test Engineering
Turning engineering requirements into reliable production decisions
Production testing must operate differently from development testing.
The production environment requires speed, repeatability, maintainability and clear decision-making while still providing sufficient technical confidence.
Sable Logic can help develop and improve production test processes by considering:
- Test cycle time
- Test coverage
- Equipment capability
- Product variation
- Measurement accuracy
- Fixtures and interfaces
- Operator interaction
- Automated sequencing
- Error handling
- Pass/fail criteria
- Test data and traceability
- Maintenance and calibration requirements
Where existing test processes are inadequate, we can also support the development of new or upgraded test systems through our Test Systems Development capability.
Process Capability & Manufacturing Quality
Ensuring the process can consistently produce the required result
A product may pass inspection while the manufacturing process remains unstable or incapable.
Sable Logic can support manufacturers in assessing and improving process capability by examining the relationship between process variation, product requirements and measurement performance.
This may include:
- Process performance assessment
- Identification of critical process parameters
- Variation analysis
- Quality-control points
- Production test performance
- Process monitoring
- Defect trends
- Quality data review
- Corrective-action effectiveness
- Manufacturing risk assessment
The objective is to move quality control upstream, thereby reducing dependence on final inspection and creating greater confidence in the manufacturing process itself.
Measurement & Test-System Capability
Reliable quality decisions depend on reliable measurements
A quality decision is only as good as the test or measurement system behind it.
Sable Logic brings metrology and test-system expertise into quality engineering to help determine whether the measurement process is capable of supporting the required decision.
This may include consideration of:
- Measurement accuracy and resolution
- Calibration status
- Measurement traceability
- Measurement uncertainty
- Repeatability and reproducibility
- Reference standards
- Test-system correlation
- Measurement drift
- Test limits
- Acceptance margins
Where the measurement process is not sufficiently capable, we can support improvement of the existing method or development of a new test solution.
Root Cause & Failure Analysis
Understanding why failures occur, not just where they are detected
A failed product does not necessarily indicate the point at which the failure originated.
The cause may lie in the design, material, manufacturing process, test method, configuration, software, equipment or measurement system.
Sable Logic can support structured engineering investigations that bring together technical evidence from multiple sources.
Depending on the problem, this may include:
- Measurement accuracy and resolution
- Calibration status
- Measurement traceability
- Measurement uncertainty
- Repeatability and reproducibility
- Reference standards
- Test-system correlation
- Measurement drift
- Test limits
- Acceptance margins
Where additional evidence is needed, we can develop test methods, software tools or data analysis to support the investigation.
Test Data & Quality Insight
Turning test results into information that improves the process
Production test data can provide much more value than a pass/fail result.
When properly structured and analysed, test data can reveal trends, recurring failure modes, process drift and differences between products, materials or production equipment.
Sable Logic can support the use of quality and test data for:
- Yield analysis
- Failure trends
- Defect Pareto analysis
- Process monitoring
- Test-result correlation
- Product history
- Quality containment
- Engineering investigations
- Equipment performance
- Continuous improvement
Where required, these capabilities can be integrated with our Manufacturing Data & Traceability solutions to create a stronger connection between test results, product genealogy and manufacturing history.
Quality Engineering Across the Product Lifecycle
Quality controls should evolve with the product
The testing and quality activities required during development are not always the same as those needed during production.
Sable Logic can support quality and test engineering across the full product lifecycle:
Development
Requirements, verification planning, validation and test-method development.
Industrialisation
Production test strategy, process controls, equipment readiness and manufacturing validation.
Production
Routine testing, process monitoring, measurement capability and quality improvement.
Field & Support
Failure investigation, product history, containment and corrective action.
This lifecycle approach helps ensure continuity between product development and long-term manufacturing performance.
Improving Existing Test & Quality Processes
Existing processes often contain significant improvement potential
A quality or test process does not always require complete replacement.
In many cases, meaningful improvement can be achieved through better test coverage, improved measurement capability, automation, clearer acceptance criteria or more effective use of data.
Sable Logic can assess existing systems and identify opportunities to improve:
- Test effectiveness
- Measurement capability
- Production throughput
- Repeatability
- Automation
- Traceability
- Operator interaction
- Result interpretation
- Data availability
- Maintainability
This allows customers to improve quality capability while retaining equipment and processes that continue to provide value.
From Quality Problem to Engineering Solution
Quality challenges frequently reveal a wider technical requirement.
A recurring failure may require improved process controls. Inadequate test coverage may require a new test system. Poor traceability may require better production data. Measurement uncertainty may require improved metrology capability.
Sable Logic brings together quality engineering, test-system development, metrology, automation, software and manufacturing expertise to address the problem at the appropriate technical level.
The aim is not simply to identify a defect, but to strengthen the engineering system that determines whether the product consistently meets its requirements.
