As opposed to the traditional software development lifecycle (aka waterfall), today’s Agile and DevOps-based software development process is more outcome-oriented. The unrelenting pace of the changing market landscape has made the hybrid, Agile plus DevOps way of software development absolutely critical in addressing customer demands and staying competitive.
The focus on Agile and DevOps is necessary due to the high failure rates of traditional software development methodologies. These failure rates are mainly attributed to the glitch-infested, low-quality applications churned out by following legacy methodologies.
The failure rates had left many companies to bite the dust and brought the key role played by quality in ensuring customer satisfaction and ROI for the business into sharp focus. Also, the IT landscape is witnessing developments such as mergers and acquisitions, increased focus on risk and compliance, data and analytics, the fast rollout of apps and mobile commerce, among others. These have necessitated the software development process to become increasingly agile, streamlined, collaborative and flexible. The reshaping of customer expectations is letting organizations to go beyond shift-left testing or DevOps testing by transforming the QA process into one driven by quality engineering.
To meet the growing demand for quality software applications in double quick time, a mere tweaking of the software development process is not enough. What is needed is the adoption of software quality engineering process comprising optimal quality assurance, predictive analytics and monitoring of QA elements to reduce glitches to negligible levels. The process would involve a continuous cycle of feedback and quality improvement based on the same. The quality engineering process offers maximum test coverage in the shift-left scheme of things and ensures outcomes like functionality, security, accessibility, usability, performance and reliability of the software application. It complements Agile and DevOps methodologies and ensures their outcomes to remain consistent with the desired business objectives. Quality engineering, instead of identifying the inherent glitches in the SDLC, focuses more on preventing them altogether.
