Quality assurance is more than just manual testing. Today’s systems are more complex than traditional approaches can handle. New automated test techniques have evolved allowing machines to exhaustively and automatically test themselves for errors. Compared to traditional manual testing techniques, automated testing can save over 80% of the cost and time of manual testing while producing much higher levels of uptime in the initial release of a new or replacement system.
Test verification techniques have evolved to the point where it is now possible to prove that all test scenarios have been thought of and tested ensuring no functional bugs exist in the final version. For replacement, or upgrades to existing systems, automated testing efficiently executes regression tests which demonstrate the new version of the system is no worse than the original (does not generate different output for same input). In fact we have proprietary techniques that score predictive risk of a project at any point in time so that you would know the number of defects and downtime a user is likely to experience before a system is released, with up to 97% certainty.
This risk management process supports identification, measurement and mitigation of project risks. The benefits of a more sophisticated approach to Quality Assurance, besides lowered cost, quicker time to market and higher customer satisfaction are adherence to security and compliance requirements.
Four types of risk must be mitigated in order to successfully release an enterprise system today:
