QA/QC Engineering Courses

QA/QC is the combination of quality assurance, the process or set of processes used to measure and assure the quality of a product, and quality control, the process of meeting products and services to consumer expectations. Quality Assurance is a process oriented and focuses on defect prevention, while quality control is product oriented and focuses on defect identification.

EFFECTIVE TESTING & QA IMPLEMENTATION

Process: It is critical that the organization defines a process that is robust and certified by experts in order to initiate the software assurance quality culture. The process will serve as a guideline that may evolve over time. Most importantly, it should be made official and should be followed through. Improvements will be made until a mature process is established.

 Managerial Commitment: Managerial commitment should stem from the CIO to ensure alignment from each of the development managers, as well as from the development areas of each country. Everyone must be aware of the value that is added by testing & QA to the business. The process, therefore, must account for the value of the solutions that it offers to the organization.

 Personal Experience: Hiring someone as a tester that lacks necessary experience is a common mistake. It is vital to acknowledge that the position requires experience in both the business and in software development in general.

 Deliverables: As part of the software development and testing processes, it is necessary to define deliverables, such as requirements, a testing plan, and testing cases. These will guarantee that testers can effectively follow-up throughout the project from the software quality perspective.

Tool Usage: Both the use of tools for tracking and managing defects, as well as the creation of test cases and execution, are essential for increasing the maturity of the testing & QA process. The process may begin without tools, but they are a requisite for increasing execution maturity.

 Metrics: Developing and creating metrics to track the software quality in its current state, as well as to compare the improvement with previous versions, will help increase the value and maturity of the testing process (e.g. the number of components with errors in the software/the total number of components in the software; or the number of errors detected in the testing phase/total number of errors detected).

Testing Environment: Implementation of appropriate testing environments that allow developers to reproduce the system execution in production environments is crucial to the creation and execution of the corresponding test cases.

Test Data: The testing environment required for day-to-day operation should provide or ensure availability of the necessary data to enable the corresponding test execution. Even if you have developed the appropriate testing environments, developers need to access specific data required to execute the associated test cases.

Change Management: Like any other production environment, the testing environment should properly track changes in configuration, ensuring not only controlled results, but that the tests are run in environments that closely resemble those of the real production environment.

 Developer Awareness: It is critical to have an awareness process that includes management commitment at each and every business unit and for associated developers. The goal is to demonstrate that testing activities add value to their daily work.

QC Process

The quality control process is divided into three separate processes, ensuring that specialized expertise is applied to each stage of our operation. This system also provides the redundancy necessary to prevent any quality problem from evading detection.

Incoming Quality Control

• Perform approved vendor list check.

• Evaluate supplier quality records.

• Perform sampling of incoming materials based on the MIL-STD-105E standard.

• Perform dimension, visual and functional inspection of material samples.

• Monitor quality control chart of inspected properties and alert engineering staff of significant deviations.

• Continuously enhance the IQC process.

 Inprocess Quality Control

• Perform inspections on assembled and in-process materials according to IPC-A-610D standards;
• Conduct in-line automated and manual inspections
• Apply first-article inspection after process setup;
• Utilize statistical control techniques and watch for significant deviations;
• Perform in-process audits to ensure processes are up to standard, and to identify factors needing improvement.

Outgoing Quality Assurance

• Perform visual and functional inspection;
• Verify first-article inspection;
• Repeat approved vendor list check;
• Apply sampling based on the MIL-STD-105E standard
• Conduct reliability testing;
• Submit failure analysis reports and alert engineering staff.
