中文摘要：

将异地分布和SCRUM方法相结合,分析产品Backlog分解过程,提出分解过程的几种重要影响因素：优先级设置、团队地理位置、任务稳定性、团队间差异、任务工作量估算。采用问卷调查的方法收集数据,然后用SPSS软件进行数据分析,研究各因素对产品Backlog分解过程的影响。研究结果表明,优先级和任务的稳定性以及工作量估算对产品Backlog分解过程有显著影响,而团队的地理位置和团队差异则没有显著影响。研究结果有助于SCRUM开发团队更好地完成产品Backlog的工作。

英文摘要：

Combining geographically distributed and SCRUM methodology,analyze the decomposition process of product backlog,take out several vital factors：priority setting,team location,task stability,team difference and task workload estimation.Taking the method of questionnaire survey to collect data,and making regression analysis with SPSS to find the influence of factors to product backlog.It finds out that priority setting,task stability and task workload estimation have significant effect to the decomposition process of product backlog,as for team location and team difference,there aren＇t obvious influence.And this research can help SCRUM team accomplish product backlog more efficient.
