eWeaver application lifecycle management tools solve the challenges to secure and improve embedded software quality. The OSS-based eWeaver provides a web browser user interface for easy access even by geographically dispersed development teams. eWeaver accelerates practicing the agile scrum methodology and ensuring the traceability that functional safety standards require. It provides comprehensive management for any activities and artifacts throughout the V-model software development lifecycle. The processes that the tool suite covers range from requirements analysis through design, coding, testing, and review. eWeaver semi-automatically manages a series of these processes from top to bottom, and thus ensures traceability. It also contributes to efficient development by saving developers the time and effort of management tasks and reworking due to missing work and duplication of work.
