DESCRIPTION
秦之远，诺基亚西门子持续集成Product Owner，敏捷过程改进执行者。秦之远目前负责诺基亚西门子两个大型WCDMA 3G通信平台的持续集成和交付。 2007~2011年，秦之远主导了下一代WCDMA 3G通信平台持续集成和交付转型，产品发布后，质量问题仅为同类产品的30%~40%，他因此赢得了2011年诺基亚西门子Service Excellence Award冠军。 秦之远于2006年加入诺基亚第一个敏捷团队（当时团队主要成员有:吕毅，窦涵之，李程远，徐毅），他先后担任了测试驱动开发教练（TDD Coach）、Scrum Master、持续集成technical leader、产品缺陷管理经理、持续集成Product Owner。 秦之远毕业于北京邮电大学，曾就职于华为、诺基亚和诺基亚西门子。 话题介绍： 2008~2009年,我们和研发团队一起，用了1年时间把诺基亚西门子下一代WCDMA 3G通信平台转型为每日发布(SCM，过程改进，测试自动化， CI)。2009~2012,我们经历了平台扩张，人员扩招，客户增长，时至今日我们仍然具备每日发布的能力。在此过程中，持续集成如何不断深入改进？我们一起回顾这段历史: 1.2007 30人研发团队持续集成: 失败案例 2.2008~2009 80人以下研发团队的持续集成: CI 1.0 3.2009~2011 80~200人研发团队的持续集成: CI 2.0 4.2011~未来 500以上研发团队的持续集成: CI 3.0
