1 Verification, Validation & Traceability Nightmares? 5-ways to streamline these processes

2 Make life easier as a test engineer Use Technology to Help with Common Activities 1. Test Coverage 2. Gauge R & R 3. Verification of deployed solution 4. Regulatory compliance 5. Test History: servicing, repairs & returns

3 Quick Background Specialists in automated test solution provision Services Bespoke systems, support, training Products SW Tools for better ATE Dev

4 Test Coverage Have I got coverage of all test requirements? How can I demonstrate this? Test Requirements Test Solution Test results Image Placeholder

5 Test Coverage Ensure compliance from both ends How to ensure from the beginning of a project? Reduce the chance of omissions Create well defined software development program How to verify when complete? Get a measure of coverage Identify non-compliances

6 Verify when complete Requirements Requirements Gateway Test Software

7 At Start of Project Auto-code Generation Requirements Test Software

8 Gauge R+R Gauge R&R a requirement for quality Needed before live production use Requires considerable amounts of results Data Processing

9 Gauge R & R Definition Looking at measurement variation in automated test Repeatability Variation of a measure under the same conditions Reproducibility Variation when some conditions change

10 Gathering Data Item Repeatability Reproducibility Operator SAME SAME/DIFFERENT Instruments SAME SAME/DIFFERENT Test Fixture SAME SAME/DIFFERENT Unit Under Test SAME SAME

11 Measurement Variation Short Term Variation Long Term Variation

12 Automating Data Collection Automated Execution - Workflow

13 Bringing Together Data Manual Spreadsheet Automated Database Warning: Spreadsheet method can be very resource intensive

14 Our Solution with DB

15 Deployment Validation Verification Protection Traceability

16 Deployment Check Post-Deployment Runtime Multi-File Auto-Repair

17 Our Deployment Solution

18 Regulatory Compliance Production Test Stage Completion Data Retention Control of Records Sub Component Tracing Aerospace Medical Rail Automotive

19 Production Test Stage Completion End of Line Burn-in/ESS Completed Unit Sub-Assemblies Components

20 Production Test Stage Completion Manufacturing Process Operation 1 Operation 2 Operation 3 Operation 4 Unit Rework Rework Process

21 Production Test Stage Completion 1. Determine the identity of subcomponents 2. Check they have all successfully passed their required tests 3. Identify subcomponents in completed unit test results

22 Production Test Stage Completion Built Stage 1 Test Built Stage 2 Test Complete Unit Test

23 Retention Period 10-Years+ Paper Vs Electronic File vs Database Data Obsolescence Data Retention

24 Data Obsolescence Media cannot be read Documents of that format cannot be opened Documents wrongly formatted in new software version

25 Control of Test Records Identification Prevent Modification Control Access Controlled and Uncontrolled Versions

26 Test Results Protect against tampering Don t shouldn t need modifying Text, graphical and tabular data Portable

27 Using Technology DO Create report documents in PDF format Protect report archive directories from modification Store data in databases Avoid Text type files which can be easily modified Test reports without adequate identification information

28 Our Solution PDF Reporting

29 Unit Test History What is the testing history of a production unit? Useage: Production Repairs Servicing Compliance Requirements Enabling design improvement

30 PSU Voltage Example Stage Unit 1 Unit 2 Unit 3 Unit 4 Initial Test 23.8V 24.1V 24.3V 23.7V After Burn-in 23.7V 24.0V 24.2V 23.7V 1st Year Service 23.5V 24.0V 24.1V 24.4V 2nd Year Service 23.7V 24.0V 24.2V 23.9V 3rd Year Service 22.5V 24.1V 24.2V 22.8V Repair 24.1V V PSU 24V Voltage Test: Acceptable Limits 23.5V -24.5V

31 Test History Via File Archive Initial Production 14/01/13 After Re-work 20/01/13 Servicing 02/02/14 Returned - Fault Repair 06/05/14 Sub Assembly Replaced 21/05/14

32 Use Results Data Archive Initial Production 14/01/13 After Re-work 20/01/13 Servicing 02/02/14 Returned - Fault Repair 06/05/14 Sub Assembly Replaced 21/05/14
