Companies encounter various challenges in ensuring software quality, including maintaining consistency across updates, managing complex codebases, and balancing speed with thorough testing. Rapid release cycles often lead to insufficient testing, which can result in software bugs and decreased user satisfaction. Moreover, the integration of different technologies and platforms complicates quality assurance processes. Establishing a comprehensive testing framework and adhering to quality standards are crucial in addressing these challenges. Continuous monitoring and feedback mechanisms also play a vital role in improving software quality over time.
