InnovFin, a rapidly expanding fintech company specializing in mobile payment solutions, has experienced significant growth in its user base over the past year. However, this rapid expansion has exposed weaknesses in its software development processes, resulting in increased software defects, delayed feature releases, and a noticeable decline in customer satisfaction. The founders, primarily focused on technological innovation, have not yet implemented a formal Quality Management System (QMS). Customer complaints related to software glitches and security vulnerabilities are escalating, impacting the company\'s reputation. Internal audits are infrequent and lack a structured approach, leading to inconsistent identification and resolution of quality issues. The development teams operate in silos, with limited communication and coordination, resulting in duplicated efforts and conflicting priorities. Top management recognizes the urgent need to address these quality challenges and establish a robust QMS based on ISO 9001:2015 principles. Considering InnovFin\'s current state and the need to align with ISO 9001:2015, what is the most crucial initial step the company should take to begin the QMS implementation process effectively?
