A business first approach to quality assurance.

At TDK Technologies, the goals of quality assurance (QA) are to increase efficiency, make effective decisions and ensure high quality services are provided to your business.

Quality assurance requires high levels of interaction and an ability to understand the needs of the multiple people, groups and stakeholders involved in the project. It also requires enforcing your standard processes and measurable procedures that are put in place and providing corrective action or follow up as necessary.

QA specialists are involved at every stage of the software development lifecycle, from concept inception to completion of the project. They work with the team to analyze and provide input to business and software requirements and develop plans on what to test and how. QA specialists verify that the software developed for the project meets all of the requirements and performs as expected.

Engineering

Quality engineering creates and implements strategies for quality assurance in software development. It integrates methods and tools from enterprise architecture management, software product management, IT service management, software engineering and systems engineering, and from software quality management and information security management. This means that quality engineering goes beyond the classic disciplines of software engineering, information security management or software product management since it integrates management issues, design considerations and operative considerations.

Methodology

As software development methodologies have evolved, so too have the QA processes that support them. Test-driven development (TDD), for example, is a software development process that relies on the repetition of a very short development cycle: requirements are turned into very specific test cases, then the code is improved so that the tests pass. This is opposed to software development that allows code to be added that is not proven to meet requirements. TDD encourages simple designs and inspires confidence.

Testing

QA specialists perform many varieties of testing and use many tools to perform them. Testing may be done manually by creating test data and using the application as the end user would. Automated testing uses software products to mimic the actions of the user, allowing tests to be repeated or to replicate large numbers of concurrent users.

QA specialists document any anomalies they uncover and turn the information back to the development team for remediation. Testing cycles continue until the software is defect-free.
