Second, Continuous Testing establishes a safety net that allows software developers to bring new features to market faster. With a trusted test suite ensuring the integrity of the related application components and functionality, developers can immediately assess the impact of code changes. This not only accelerates the rate of change, but also mitigates the risk of software defects reaching your customers.
Third, Continuous Testing allows managers to make better tradeoff decisions. From the business’ perspective, achieving a differentiable competitive advantage by being first to market with innovative software drives shareholder value. Yet, software development is a complex endeavor. As a result, managers are constantly faced with tradeoff decisions in order to meet the stated business objective. By providing a holistic understanding of the risk of release, Continuous Testing helps to optimize the business outcome.
Fourth, when teams are continuously executing a broad set of tests via “sensors” placed throughout the SDLC, they collect metrics regarding the quality of the process as well as the state of the software. The resulting metrics can be used to reexamine and optimize the process itself, including the effectiveness of the tests. This information can be used to establish a feedback loop that helps teams incrementally improve the process. Frequent measurement, tight feedback loops and continuous improvement are all key DevOps principles.
To explore how Continuous Testing accelerates the SDLC, promotes innovation and helps mitigate business risks, we recently published “Continuous Testing for IT Leaders.” This book is written for senior development managers and business executives who need to achieve the optimal balance between speed and quality with software applications that are the primary interface with customers… and ultimately revenue.
