COMPOSITE KEY ELEMENTS ESSENTIAL FOR DEVELOPMENT AND DELIVERY OF DEFECTLESS BANKING PAYMENT SOFTWARE’S

Abstract
Payments technology has seen tremendouschanges in the last 2 decades, Themanual processing to click of a functionin this digital transformation has led to huge shift in the software development and the gamut of Banking Industry. In an intensely competitive digital economy, especially within the real-time payments landscape, quality has become a decisive factor for organizational survival and growth. Leading firms now recognize that it is not sufficient to deliver high-quality products alone—superior service quality is equally vital to sustaining customer trust and brand equity. In a sector where trust is currency, even minor service lapses can trigger customer attrition and reputational damage through rapid word-of-mouth or digital feedback loops. Empirical evidence consistently shows that poor quality—whether in the form of software bugs, system downtime, or operational inefficiencies—translates into higher costs from defect resolution, rework, regulatory penalties, and loss of goodwill. As *Kenett and Baker (1999) aptly observed, software quality remains one of the most overlooked dimensions in development, often viewed as abstract or intangible. This misperception is especially risky in mission-critical environments such as payment systems, where quality lapses may compromise financial accuracy, compliance, or service continuity. To that end, payment products must embed a culture of 'built-in quality' throughout the lifecycle—from design to deployment—backed by disciplined quality engineering, continuous monitoring, and strong leadership commitment. Only then can organizations reliably deliver on the strategic imperative of zero-defect software at scale. The Primary objective of this study is to investigate and provide the Management Strategy for the Development and Delivery of Defectless Banking Payment Softwares. Also identify the key elements and barriers which stops the quality of software in the Payment Banking industry. The outcome of the research will help the practitioners mitigate the defects and ensure the quality delivery is focussed right from the incubation of the software. Complying to the regulatory standards and customer centric which aims for defect less product. Keywords – Payment software, Quality, Management Strategy, Compliance, Composite Key
