Platform Maintenance Process for Software Quality Assurance in Product Line

As software products increase and continuously evolve, the improvement of software quality and increase of productivity are becoming crucial in consumer electronics. The software product line method, which develops software products by reusing software architecture and source code of product families rather than making separate software products, is gaining importance to achieve rapid responsiveness to market demand. As the software product line method becomes a core technology in consumer electronics, an issue that inevitably arises due to the reuse of software architecture is the management of platform quality through defect removal and continuous maintenance. This paper presents the details of the Platform Maintenance Process established to achieve such purpose, and validates the process through application in a business division which resulted in an approximate of 30% reduction in average defect fix time.
